(Article Updated - August 2024) Overview A blocklist is a database of IP addresses or domains that have been associated with the sending of unsolicited commercial email or spam. Internet Service Providers (ISPs) and business email networks use information from blocklists to filter out unwanted email. As a result there can be a drop to inbox delivery rates if the IPs or domains involved with sending email are listed on a blocklist. Marketo’s Email Delivery and Compliance team monitors blocklist activity on our IPs and domains daily. When an impactful listing occurs, we reach out to the blocklist, attempt to identify the sender that triggered it, and work with the blocklist organization to get the listing resolved. There are thousands of blocklists, most will not have a significant impact on your delivery rates. Below, we have compiled a list of the blocklists that commonly appear across our sender ecosystem. Each blocklist has been grouped into a top tier (Tier I) by most impactful, to the bottom least impactful tier (Tier III). These may have little to no impact across our sender network. Tier I Blocklist Spamhaus (SBL) Impact: Spamhaus is the only blocklist that we categorize as a Tier I for a reason: it has by far the greatest impact on delivery. It is the most well-respected and widely used blocklist in the world. A listing at Spamhaus will have a negative effect on your ability to deliver emails to your customer’s inbox and can cause bounce rates of over 50%. Evidence suggests that most of the top North American ISPs use Spamhaus to inform blocking decisions. How it works: Unlike many blocklists, Spamhaus lists senders manually. This means they are proactively watching sender activity, collecting data, and base listings on a number of variables. Most commonly senders are listed for mailing to spam trap addresses that Spamhaus owns. Sometimes Spamhaus will list senders based on recipient feedback as well. Next Steps: Please note that every Spamhaus email can be quite different depending on the information provided and the nature of the listing . Because Spamhaus has multiple types of listings, the remediation steps are based on which type of blocklisting has occurred. We have listed the most common types to affect Marketo customers, from most to least impactful. Impact can range from a full block of top severity, to a partial block that is less severe (CSS Data, DBL). If remediation isn’t performed and the problem not addressed, these listings can increase in severity and turn into a full blocklisting. Spamhaus Blocklistings Types SBL (full blocklisting) Considered the most impactful. Remediation steps: Our team monitors closely for Spamhaus listings. Once alerted to the listing, we send an email notifying the customer, and reach out to the Spamhaus contact to start the remediation process. Only a Marketo delivery team member should be in direct correspondence with the Spamhaus contact, to speak on behalf of the customer, and to relay their questions and instructions, ensuring quick resolution and reduced impact. Senders that trigger this listing on a shared IP range will be moved to a more isolated, penalty range (IPB), so as not to impact the other shared senders. Those affected on a Dedicated IP, only impact their own sending and will not be moved. However, depending on the severity of the issue, our team may need to revoke a customer’s ability to send any emails until full resolution. The listing will last until Spamhaus is satisfied that the offending sender has taken the appropriate steps to mitigate the problem. SBL CSS Customers are alerted of the listing with an email containing all the information needed to immediately begin the remediation process. This is part of an automated trigger listing, that allows for a customer to delist directly on the Spamhaus website, after they’ve completed remediation. Remediation steps: Customers will go to the Spamhaus IP lookup website, at https://check.spamhaus.org, where they can check on the status of their IP and continue to monitor it in real time, until it is no longer listed there. Follow the remediation and delisting instructions provided, and check for specific details in the blocklist notification email. DBL (Domain blocklisting) Customers will receive an email notification alerting of the company domain being listed. The email will contain specific information to help narrow down and identify which email source likely triggered it within Marketo. It’s important to note that any email sent from outside of Marketo, that contained the company domain, is suspect. This means, if the sender uses multiple IPs and/multiple email platforms, then any of those could be the source. Remediation steps: Follow the detailed instructions in the email, which will also provide a link to the Spamhaus Domain reputation checker webpage, to check the real time listing status of the affected domain. Once the email source is identified and cause addressed, this customer will follow the online instructions to request to be delisted. Tier II Blocklist SpamCop Impact: SpamCop is not used by any of the major North American ISPs to inform blocking decisions, but it makes it to the Tier II list because it can have a significant impact on B2B email campaigns. SpamCop is considered a Tier I one blocklist for B2B marketers but a Tier II for B2C marketers. SpamCop is a dynamic IP blocklist, that can affect a single IP or a subset of IPs Typically, the block will automatically lift within one business day, but can take longer for relisted IPs. To have triggered a SpamCop listing likely means the sender has a list management problem that should be addressed. How it works: SpamCop lists IPs for one of two reasons: Either the email hit SpamCop spam trap addresses OR A SpamCop user has reported the email unwanted. Most of SpamCop’s spam traps are previously valid addresses that have not been active for 12 months or longer. Remediation steps: If you are seeing a significant number of bouncing emails caused by a SpamCop blocked IP but aren’t sure if your email activity triggered the listing, first identify whether you are sending on a shared sender network or not. If sending from a shared IP range when this occurs, you or any other customer sending from the same network may have contributed to the IP block. This IP block will automatically get dropped within a business day. For those on a Dedicated IP that trigger a listing, refer to the above remediation steps and resources, to address the list management issue. Tier III Blocklist (Low/ No impact ) These are considered the lowest tier and therefore cause the least impact across the Marketo sender ecosystem. Some of these blocklists were more impactful at one time, while others are only impactful based on the sender region (Manitu). Others still can suddenly flare up (Lashback). There are also many blocklists that are ignored (0spam), and are not taken seriously because they do not provide any means to delist once on the list (NoSolicitado) or that they charge money to have the listing removed ( UCEPROTECT ). The pay-to-delist model is not well respected in the email industry. When using blocklist tool checkers, such as MXToolBox, many blocklists will appear, but very few are relevant. Here is our selection of Blocklists you may come across that are least impactful: Project Honey Pot SpamAssassin URIBL/SURBL DrMX PSBL 0spam HostKarma Ascams ZapBL Barracuda Trendmicro Inc. Cloudmark Proofpoint Invaluement ISP Blocklists Some ISPs use internal blocklists to make blocking decisions. Examples include AOL, Yahoo, Gmail, Outlook and Hotmail. If your IP is being blocked by one of these networks, and those networks have a large presence in your lists, a block of this kind could have a noticeable negative impact on delivery. Marketo monitors for significant ISP blocks. Those experiencing deliverability issues with emails not making it to the Inbox and bulking in the spam folder may benefit from additional services with our Email Delivery Consultants. Remediation Steps: Email Delivery Compliance Team works to resolve any ISP blocks. ISP blocks are are usually resolved or lifted within less than 24 hours of a delisting request. Customers experiencing significant blocks for Microsoft domains (outlook.com, live.com, microsoft.com), can submit a request to the delivery team to seek mitigation on their behalf.

Issue You have been sending live emails (non-samples) to yourself or colleagues to test functionality of an upcoming email blast, and even though you may be opening the email, you are not seeing the open email activity on the Lead Activity Log. Solution Note that there may be a slight delay between opening the email, and the activity displaying on the Log. Marketo considers an "open" to be when the images in the email are downloaded, specifically a single-pixel tracking image. The recipient may be receiving the emails and viewing them, but not downloading the images. This would not count as an "open." Please note that since text-only emails have no images, so they will never log an Open activity. If the images are being downloaded, and you are still not seeing the activity after about 5 minutes, check to make sure there are no duplicate leads that are logging the activity instead. If you need further assistance, please contact Marketo Support.

Issue There are two filters available (Acquisition Program and Acquisition Program Name), but only Acquisition Program Name appears in the lead record and is available as a column in the lead views. What is the difference between these? Solution Acquisition Program is a system-managed field. It isn't available in many picklists, nor in certain filters. Acquisition Program Name is a field that allows you to use this data more freely as it is not locked by the system. Acquisition Program = Master naming for programs Acquisition Program Name = Friendly usable name

Overview A triggered campaign launches automatically when a specific action occurs. For example, you can use a triggered campaign to automatically send an email to a lead after she completes a form. Triggered campaigns have at least one trigger in their Smart List. When the lead activates a trigger and passes through the other filters in the Smart List (if you have any), the lead will immediately proceed through the campaign's Flow. In a Smart Campaign, the Smart List palette contains a separate folder with Triggers. These are the events you can use to activate your triggered campaigns. Be careful when using multiple triggers. If you use two or more in a campaign, any single trigger can activate the campaign. Email Triggers Trigger Name Description Clicks Link in Email If someone clicks on a link in an email. This can be a specific link(s) or any link. Email Bounces If an email bounces from an address. Email Bounces Soft If an email bounces due to an auto‐reply, full mailbox, etc. Email is Delivered If an email is delivered to someone. Opens Email If someone opens an email. Unsubscribes from Email If someone opts out of email. Salesforce Specific Triggers Trigger Name Description Activity is Logged If an activity is logged in salesforce.This can include a logged call or task created. Activity is Updated If an activity that is already created is updated. Added to Opportunity If a contact is added to an opportunity. Added to SFDC Campaign If a lead/contact is added to a Salesforce campaign. Clicks Link in Sales Email If someone clicks a link in a sales email (an email sent through Sales Insight). This can be a specific link(s) or any link. Is Sent Sales Email If someone is sent a sales email (an email sent through Sales Insight). Lead is Converted If a lead is converted into a contact in Salesforce. Lead is Deleted from SFDC If a lead is deleted from Salesforce. Lead is Synced to SFDC If a lead is synced to Salesforce from Marketo. Opens Sales Email If someone opens a sales email (an email sent through Sales Insight). Opportunity is Updated If an opportunity is updated. Owner Changes If the owner of a record in Salesforce changes.This can be to a specific user or to any user. Removed from Opportunity If a contact is removed from an opportunity. Removed from SFDC Campaign If a lead/contact is removed from a Salesforce campaign. Sales Email Bounces If an email bounces from an address. Sales Email is Received If an email sent via Sales Insight was delivered. Status is Changed in SFDC Campaign If a lead/contact status changes within a Salesforce campaign. General Triggers Trigger Name Description Added to List If a lead/contact is added to a Marketo static list. Campaign is Requested If a contact/lead is sent into a Marketo campaign. Clicks Link If someone clicks on a link. This can be a specific link(s)or any link that is tracked. Data Value Changes If any data value on a record, includes all fields available for edit/update in Marketo and Salesforce is changed. Fills Out Form If someone fills out a form. Has Interesting Moment If someone has an interesting moment. Lead is Created If a Marketo lead is created. Removed from List If a lead/contact is removed from a Marketo static list. Revenue Stage is Changed If a revenue stage within a revenue cycle model is changed. Score is Changed If a lead score is changed. Send Alert If someone does something, send an email alert. Visits Web Page If someone clicks and visits a web page.This can be a specific page(s) or any web page.

Issue Our organization understands that Marketo has a durable unsubscribe field. Is that the only field that is durable or are other fields like block listed, marketing suspended, etc... durable? The scenario here is if someone is deleted, then later comes back in via SFDC for example -- are other fields durable and thus, carry over to a newly created record with the same email address? Solution The durable unsubscribe is the only field that will persist if the lead re-enters Marketo. This is because we host that data in a separate database, whereas fields such as 'Block Listed' are hosted in your local database. (When the lead is deleted, then all data is wiped for that lead in the local database.)

Issue A lead shows as being a member of a campaign that had a single flow step of 'Change Data Value'. However, the lead doesn't show in the Results tab of the campaign, nor is the CDV activity logged in the activity log for the lead. Solution This can happen if the field to be updated was blank/null, and the new value in the CDV flow step is derived from another field, using a token, and this other field is also blank. Because the value 'changes' from blank to blank, we don't log anything in the activity log, but the lead is a member of the campaign.

Summary This article explains why certain Company fields show up on the Person/Lead Object when you do a describe API call to Marketo. Issue When making the Describe call on the Lead object in Marketo (/rest/v1/leads/describe.json), several Company object fields are returned along with the Lead object fields. Environment Marketo REST API Solution This is expected behavior. Users can utilize the Describe Leads call to retrieve a full list of the fields available for interaction via the REST API. Several areas within Marketo treat custom Company fields as though they were on the Person/Lead object. For example if you were doing a Bulk Import, you can target the Company and Person/Lead fields and you have the ability to update Company field values as if you were changing it manually on a Person record in the UI. Root Cause This is expected behavior, due to how the Describe call retrieves all

Summary Aggregating/summing two score fields Issue You have two new score fields (for example: 'Implicit score' and 'explicit score') and you're wondering if there's a way to sum/aggregate these scores together for all records within Marketo. Solution To aggregate different score values together within Marketo, you should first create a third 'sum' field meant to capture the aggregate of the two scores. (Example: 'sum score') Now, we have 3 scores: Explicit Score, Implicit Score, and a Sum Score SOLUTION First, setup the scoring smart campaigns for implicit and explicit score as you normally would. Once those scoring programs are setup, add the sum score field to the flow of each respective campaign, increasing that score by the same interval that you increase the implicit or explicit score by. This should allow the scores to aggregate over time. Example 1 "Implicit Scoring campaign: Trigger: Visits web page 'x' Flow: 1. Change Score [Implicit score] Change: +5 2. Change Score [Sum score] Change: +5 Explicit Scoring campaign: Trigger: Fills out form 'y' Flow: 1. Change Score [Explicit score] Change +10 2. Change Score [Sum score] Change +10 Final result if a record runs through both campaigns > Implicit score: 5, Explicit score: 10, Sum score: 15" In the above example, the sum score flow step is simply added to each respective explicit/implicit scoring campaign, with the same change interval applied. Once applied to all relevant scoring programs in the instance, the sum score should continue aggregating the two scores into the sum score field. If you're increasing both explicit and implicit scores within one campaign instead of separating out by score type, you could also accomplish this with the same logic and instead adding the summed score interval within that same flow, for example: Example 2 "Scoring campaign: Trigger: Person is created Flow: 1. Change Score [Implicit score] Change: +3 2. Change Score [Explicit score] Change: +4 3. Change Score [Sum score] Change: +7 Result > Implicit: 3, Explicit: 4, Sum: 7" -------------------------------------------------------------------- Potential Alternative solutions: 1. Have your SFDC/CRM Admin create a workflow within the CRM which sums the two fields as they sync. This requires the score fields in question to be synced to the CRM. 2. Call a webhook, which will keep the aggregate in line with the individuals each time it's called. This would be a custom webhook implementation that Support cannot assist with.

Issue You added yourself to the Send Alert To portion of the List Import process and continue to receive unwanted Alert Emails every time a list is imported. Solution During the next List Import process to the problem Static List in Marketo, you'll want to select the Edit Send Notification from the window that pops up in the top right section of your screen after the import process is started. Selecting the Edit Send Notification will cause a new window to open up that shows all of the email addresses who will be sent an Alert Email once the import completes. If you no longer want to receive the Alert Emails for this static list going forward, deleteyour email address and click save.

Issue Person record's Activity Log shows repeat Company Name changes without any Data Value Change being logged. In this example screenshot, we can see that the person had the Company Name set back to the correct value by the CRM sync, but there is no record of the Company Name being changed in the first place. This is a article attached image Environment Person records showing the change are all part of the same Account. One person on that holding Account fills out a form that updates the field "Company Name" to a value that is different from the Account Name CRM sync corrects the Company Name field back to Account Name Solution STEPS TO RESOLVE: 1. Find the lead that change the Company Name field on the account with a Smart List filter: DATA VALUE CHANGED Attribute: Company Name New Value: [Company Name from form fill-out] Previous Value: [Account Name] This is a article attached image 2. Locate the Data Value Change in the Activity Log 3. Check the date and time of the Data Value Change 4. Check that timeframe on other affected records 5. The timeframe of the Data Value Change back to the Account Name will approximately match the timeframe of the logged Data Value Change, showing that the update to the one person was the cause of the update for all others on that account. Root Cause Marketo uses Company Name as the identifier for the Account object. If you have multiple people on the account and one of them changes the Company Name via a form fill-out, the Company Name is changed for all other people on that Account. This change happens on the back end, so you will not see it until the CRM changes it back to the correct value in the next sync cycle.

Issue Lead activity log shows "Change segment" or "Add to Segment" for a segmentation (i.e. "Change Title to "Directors") The named segmentation ("Title") does not show up in the segmentation list in Database Environment Marketo instance with the Target Account Management feature Solution Even though the activity log shows a segment activity, the segment is actually a Persona, which is a feature of Target Account Management.

Issue If a record which is in a Marketo Campaign Wait Step and is merged into another record, does the winner of the merge continue through the flow? Solution Winner of the merge will continue through the Campaign flow and complete the remaining steps. To prevent this behavior, remove the record from Campaign using the 'Remove From Flow' step. Environment Records merged in Marketo Records merged in SFDC

Issue Single Flow Step to send an email to x number of leads failed Solution Create a smart campaign and override the person restriction to send an email to a number of people that is greater than the campaign restriction Root Cause The number of people selected to send an email from a single flow action exceeds the campaign person restriction/limit. The campaign restrictions apply to the single flow action because a background campaign is generally created to process the single flow action. Environment Single Flow Action Send Email Campaign Restrictions Smart List

Summary duplicate records with the same email across lead partitions can be affected by uploaded custom object activity Issue System not separating lead partitions for custom object imports Uploading custom object activity affects duplicate records across partitions Custom Object activity import writing to the most recently updated record regardless of partition Solution Use the following workaround: Run an update on the records that should be affected by the custom object activities import. This will make sure they are the most recently updated records among the duplicates Root Cause Normally when you do a list import, it would import into the one partition, whatever partition the list is located in and only impact the record in that one instance. But when you import a Custom Object, it's able the see ALL the records across ALL the partitions. If there are duplicate records, it just looks to see which one was updated most recently and grabs that one for the list import. So if you have lead record in A with Add to Custom Object already completed and you re-import again but the lead record in B has been updated more recently and has NOT had the custom object added to it, you get the duplicate "Add to Custom Object" activity. Environment Multiple lead partitions with duplicate records across them Custom Object activity import

Issue Leads recently imported cannot be found Solution Check if the example leads exist in the partition the workspace has access to. It is possible that the leads cannot be found because the workspace being checked does not have access to the partition the leads exist in. Check if any of the example leads have been deleted: by using the Campaign Inspector to review all of the smart campaigns that contain a Delete Lead flow action. Then check the run history of each smart campaign to see which recently ran and how many people qualified. If there is a significant amount of smart campaigns that contain a delete lead flow action, contact Marketo Support for additional assistance. by checking the delete lead activities via API Check if the example leads' information was changed. For example, if a lead was imported with email address "john@gmail.com" then create a smart list using "Data Value Changed" filter where "previous value" was "john@gmail.com" Root Cause Leads could exist in a partition that has not been searched, the details could have changed, or the leads could have been deleted.

Summary Estimating the external storage requirements for your Marketo Engage Database Issue I want to extract all of my data from Marketo Engage and store it. How much storage space will I need? Environment Marketo Engage and External Systems Solution Summary There is no repeatable method to accurately estimate the amount of storage you will need to extract and store your Marketo Engage database. Standing in the way of good estimation is data availability, field selection, and storage method. Any accurate estimate will take into account the potential sizes of each type of data and their quantities (known to data scientists as "facts and dimensions"). Determining ranges for these values takes a lot of preparation and may require a high level of skill. IMPORTANT NOTE: Estimating Database size is hard so any estimate used to make business decisions should be made in cooperation with a database or application architect or other qualified professional. Scope Some information won't be extracted. Information about anonymous leads, for example, cannot be extracted. Some of the data that can be extracted may not be needed at all. Selecting the right data for your needs is the best practice as it reduces the required storage and leads to a more efficient extraction process. Field Definitions How the fields are defined in the target system will affect how big the stored data is. Depending on your storage format, padding may play a role in the size of your extracted database. As an example, the "Country" field in Marketo is a string of up to 255 characters. You could chose to store 255 characters for every country value. Or you may choose a format that uses a variable amount of space. You might also know that the longest country name is "the United Kingdom of Great Britain and Northern Ireland" meaning that 199 of those characters will always be extra so you truncate the value from Marketo storing the first 56 characters only. Each choice will have an impact on the size of your extracted database. Estimating 199 unnecessary characters per lead and making similar decisions for other fields will add up to increased storage requirements and slower extraction time. Format Once the desired data is identified, the next step is to extract, transform and load (ETL) the data from Marketo Engage into your storage system. The data returned by Marketo's API is plain old text which is usually formatted as JSON or CSV. For the information to be useful, you will transform it from JSON into the format necessary for your storage system. That format could be an Excel spreadsheet, Microsoft SQL database or a schema-agnostic database like Azure Cosmos DB. How the data is formatted and encoded will make a big difference in the amount of storage needed. Take this simple example: a Microsoft Excel spreadsheet with "Marketo Engage" in cell A1. I saved that same file in four different formats which resulted in files ranging from 1 KB to 25 KB. The format you store you information in may have a bigger impact on your final storage requirement than the data itself. This is a article attached image To help illustrate the impact of the storage system, take a look at this guide for Microsoft SQL Database size estimation: https://docs.microsoft.com/en-us/sql/relational-databases/databases/estimate-the-size-of-a-database Functionalization Once you've extracted your data, what are you going to do with it? Archiving your data (simply storing it) is easiest and comes with the fewest contraints. A compressed archive (Zip file) will save dramatically on storage space at the cost of functionality and ease of use. Functionalizing your data (using it in an application) requires more: at least better speed and searchability: typically a relational database. An application will often require additional data and that will need to be accounted for too. Facts and Dimensions: Do the Math It's a lot of work to get to this stage. Once you've determined how your extracted data will be stored, you can set upper and lower bounds on the sizes for each object type extracted (lead, email, activity, etc). These are your facts. Then multiply those values by the number of each type of record. These are your dimensions. Add to that the overhead of your target storage system and its functional requirements to generate your final estimates.

Summary Unable to update Person Source as expected for records created with the LinkedIn Lead Gen Forms and Facebook Lead Ads integrations. Issue New records created through LinkedIn Lead Gen forms as well as Facebook Lead Ads results in the records not updating the Person Source field as expected. Solution Person Source may be set to block updates to the field as noted in the example for Block Updates to a Field - Marketo Docs - Product Documentation. To resolve the issue ensure the field is not set to block updates for the desired update method. Alternatively the Person Source values populated by the integrations can be kept and expected values can be updated to include these sources. Root Cause The LinkedIn Lead Gen Forms and Facebook Lead Ads integrations automatically update the Person Source to preset values when a new record is created in Marketo through the integrations. Blocking field updates to the field may prevent the value from changing to pre-configured values as a value already exist for the integration created records. Environment LinkedIn Lead Gen Forms Facebook Lead Ads

We have enhanced the behavior of the unsubscribe functionality to make it “durable”. We have added a master email status, which is separate from the unsubscribe flag visible on the lead detail record. If the unsubscribe flag is set from false to true, the master email status is updated, and the change is propagated to other leads with the same email address. Update the Unsubscribe flag from True to False (e.g. Re-subscribe a lead) When a lead is imported, the unsubscribe flag WILL NOT be overwritten by the import. Here are the ways a lead can be re-subscribed: 1. In SFDC, uncheck the Email Opt Out field. This WILL sync to Marketo. 2. Manually update the lead detail record by un-checking the unsubscribe flag 3. Run a Change Data Value Flow Action on one or many leads a. Select the attribute “unsubscribe” and set the value to False 4. Update an existing lead via SOAP API 5. Form Field – set a field on a form to set the unsubscribe flag to “false” and this will unsubscribe the lead a. Best practice would be to have text on the form that says that by filling out this form, they are agreeing to receive email communication Creating a New Lead When a new lead is created, we check it against the master email status table. If the lead was previously unsubscribed, we will update the record to be unsubscribed. Changing an email address If you change the email address of a lead to an unsubscribed email address, the lead will be unsubscribed. This change can occur in either Marketo or SFDC. If you change an unsubscribed email address to one that is subscribed, the lead will be subscribed.

Issue Description: The Activity Log shows "Fill out a form" without a page visit. How users could fill out a form without visiting the page? Issue Resolution: Google Chrome introduced Incognito. Firefox, Safari, Opera and Internet Explorer implemented Private Browsing. Pages that users visit in Private Browsing/Incognito will not leave traces, like cookies, on users' computers after they close all open windows. A normal visit to any page is not tracked during visits, regardless the navigation path. That includes other pages after the form is filled out. The new Do Not Track feature is a contributing factor for apparently incomplete Activity Logs. When users turn on the Do-not-track feature, the browser tells every website they visit (as well as their advertisers and other content providers) that they do not want their browsing behavior tracked. Honoring this setting is voluntary — individual websites are not required to respect it. Websites that do honor this setting should automatically stop tracking your behavior without any further action from users.

Question: Is it possible to assign a lead owner during a list import? Answer: No. The reason for this is because lead ownership is a Salesforce functionality and should be first done from within Salesforce. If you are not able to do the assignment in Salesforce, here is one option that is available to you within Marketo: 1) Upload your leads into Marketo's Lead Database without lead owner information. i.e. your import CSV will not have any lead owner column in it. More information on importing leads can be found here: Import a List of Leads from a Spreadsheet into Marketo (Import List). 2) Once the list import is successfully completed and your leads are in Marketo, you can use the "Sync Person to SFDC" flow action to assign lead ownership. More information on the "Sync Person to SFDC" flow action at Sync Person to SFDC.
