Create a Program to house everything 3. Create a Static List 4. Create two Smart Campaigns Smart Campaign One - Logging Email Bounces with Bounce Details Smart Campaign Two - Remove Leads From the List After Successful Deliveries 5. Create Custom List View Showing Bounce Details Overview Bounce activities carry details for why the email was bounced, but it’s housed within the activity log entry, not in a field on the lead record, so it’s difficult to export that data. This article will show you how to extract that information to create a directory of leads bouncing emails and how to make the list automatically update. This will also create counters for bounces and successful re-deliveries after bounces happen. Data you’ll get from Email Bounces Bounce Categories Email bounces come in different types depending on why the email was bounced; Hard Bounces or Soft Bounces. Hard Bounces Hard Bounces come in two types, Category 1 and Category 2. Category 1 bounces are emails that have been marked as spam by the recipient mail server. Many email servers monitor blacklists or spam traps, so after de-listing with them, leads that have had a Category 1 bounce previously may be able to receive emails again. Category 2 bounces occur due to an email address that is invalid or doesn’t exist. Soft Bounces Soft Bounces come in three different types, Categories 3, 4 or 9. Category 3 bounces are usually temporary, caused by full mailboxes, timeouts, or throttling. Any email with this designation has been retried for up to 24 hours (36 for AOL). Category 4 bounces are caused by technical problems, Transient Failures, Admin Failures, DNS Failures. Any email with this designation has been retried for up to 24 hours (36 for AOL). Category 9 bounces are unknown, undetermined or gibberish details. Any email with this designation has been retried for up to 24 hours (36 for AOL). Bounce Details When an email is bounced, the recipient mail server includes details of why it was bounced. These are created by the admin of the recipient mail server and vary greatly, but most will give some explanation that can give valuable information. Email Bounce Codes Building the Directory 1. Create 6 custom fields You’ll need 6 custom fields, two DateTime fields, two Score fields, and two String fields Name the DateTime fields “Bounce Date” and “Email Delivered After Bounce”. Name the Score fields “Email Bounces” and “Deliveries After Bounces” Name the String fields “Email Bounce Details” and “Email Bounce Category” Directions for creating Custom Fields can be found here: Create a Custom Field in Marketo 2. Create a Program to house everything Use a default program type and name it "Directory of Leads Bouncing Emails". Info on creating programs can be found here: Create a Program 3. Create a Static List This static list will be your actual directory that contains all of the leads that are currently bouncing emails. Name it "Active Bounce List". Info on creating a static list can be found here: Create a Static List 4. Create two Smart Campaigns These two Smart Campaigns are what will be used to add and remove leads from your active bounce list. Info on creating Smart Campaigns can be found here: Create a New Smart Campaign Smart Campaign One - Logging Email Bounces with Bounce Details Your first Smart Campaign will be used to listen for any email bounces that occur. The campaign will populate the “Bounce Date”, “Email Bounce Category” and “Email Bounce Details” fields. It will then add one point to the “Email Bounces” score field which can be used to count how many bounces have occurred per lead. Lastly, the campaign will add the lead to the static list which will be an active directory of leads who are bouncing emails. Campaign Smart List Use the two triggers of “Email Bounces” and “Email Bounces Soft” in the Smart List. Set both triggers to “is any” so that they will fire whenever any email bounces for any reason. Campaign Flow The Flow of the campaign will have 5 flow steps. The flow will use a System Token and some Trigger Tokens, which can be used to pull details out of the action that activated the trigger. In this case, the Trigger Tokens will be pulling out the details on why the emails were bounced. That info is in the bounce message and is logged in the lead's activity log. Normally you'd have to comb through the activity log one at a time to find these details for each individual lead. This method, however, will pull the details out automatically for all leads. Flow Step 1: Change Data Value Attribute: “Bounce Date” New Value: {{system.dateTime}} Flow Step 2: Change Data Value. Attribute: “Email Bounce Category” New Value: {{trigger.category}} Flow Step 3: Change Data Value Attribute: “Email Bounce Details” New Value: {{trigger.details}} Flow Step 4: Change Score Score Name: “Email Bounces” Change: +1 Flow Step 5: Add to List List Name: “Active Bounce List” Smart Campaign Two - Remove Leads From the List After Successful Deliveries Campaign Smart List The Smart List of the campaign will need a trigger for “Email is Delivered” set to “is any” and also a filter of “Member of List” looking just for leads that belong to your Static List. This way, the campaign will only apply to leads who have had an email bounce but have then had an email successfully delivered afterwards. Campaign Flow The Flow of the campaign will have 3 flow steps to do the following; log when the email was delivered, add a point to the "Deliveries After Bounce" Score Field, and remove the lead from the "Active Bounce List". Flow Step 1: Change Data Value Attribute: “Email Delivered After Bounce” New Value: {{system.dateTime}} Flow Step 2: Change Score Score Name: “Deliveries After Bounces” Change: +1 Flow Step 3: Remove from List List Name: Operational.Active Bounce List 5. Create Custom List View Showing Bounce Details The custom fields you’ve created for email bounce information won’t show automatically in the view of your list. You can create a new view of the list to show just this information so that when it is exported it will give you only the email bounce information you need. Once the list has the necessary details, it can be exported with those columns included so that you can work with it. You can identify emerging trends and issues with your deliverability by looking for common themes among the bounce details. Directions for creating Custom Views can be found here

(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 After creating an Email Program with an A/B test, you create smart lists (or smart campaigns) and would like to use filters such as "Opened Email" for the A/B test email. When starting to type the A/B test email name into the smart list filter, the A/B test email name does not show as available to select (it may show a red squiggly line). Solution The Email Program (with the A/B test) needs to be in "Approved" status before the A/B test email assets can be entered into a smart list filter.

Issue My SFDC production instance is undergoing Instance Refresh Maintenance in SFDC. Will this impact the SFDC and Marketo sync? Salesforce Article: Help And Training Community Solution Provided the org ID of your SFDC environment stays the same, it will remain connected to your Marketo instance. As best practice, double check with your SFDC team that all of your SFDC records will retain their unique IDs after the refresh. After the refresh occurs, double check that the Marketo connection in Marketo (under Admin > Salesforce) is intact.

Issue Sometimes email addresses that are CC'd can have emails bounce. This doc describes what to expect in these scenarios. Solution Sending Emails To address is valid, cc address bounces The email will be sent to the recipient but the cc'ed recipient will not receive it (since the address is invalid). Nothing in the Marketo UI will communicate that the email to the cc'ed address was undeliverable. To address bounces, the cc address is valid The email to the recipient will bounce normally. The cc'ed recipient will still receive a copy of the email. Nothing in the email sent to the cc'ed recipient will tell them that the To: the address was undeliverable. To address is valid, cc address is unsubscribed The email to the recipient will deliver normally. The unsubscribed cc address will not receive the email. Nothing in the UI will reflect that the cc'ed recipient did not receive the email because of an unsubscribe setting. The cc'ed address will not appear in the Send Email activity under the cc'ed attribute. Email Delivered This will not include details of the cc'ed email addresses. There is no log item in the UI to communicate that a CC email was delivered to the recipient or bounced. Emails in the inbox The cc'ed person will be in the cc field of the email the lead receives. The links in the email will be tracked for the person in the To: line. If the cc'ed person clicks the links in the email, the 'Click Link' activity will be logged on the lead in the To: address and the cc'ed recipient will be cookied by Munchkin as the person in the To: address.

Issue You have a Batch Campaign or Email Program setup where the amount of people qualified is more than what's listed under the Smart Campaign Person Restrictions limit (for more context, see Enabling Person Restrictions for Smart Campaigns). Within that same program or campaign, you calculate that between the number of qualified people reduced by how many are blocked from processing puts the total count of records below the Person Restrictions for the instance. Would the campaign or email program still execute and process the appropriate leads that aren't blocked or does Marketo solely look at qualified members to determine if that's more than allowed based on Person Restrictions? Environment Admin Marketing Activities Marketo Scheduling Solution Yes, the campaign will still run as expected. Both Email Programs and Smart Campaigns effectively disqualify non-marketable people before processing records towards the Campaign Processing limit. Example: Your instance is setup to limit campaigns from processing more than 500k records in a given Smart Campaign. If you have 600k qualified for your Smart List (Audience) but 200k of the records are blocked, the campaign will still run as only 400k marketable people qualify to actually get processed through the campaign. Blocked records don't get processed through the campaign execution and, therefore, don't add or contribute to campaign processing limits.

Issue List Import shows other lists Pending Import import even though you are only importing one list. Solution The List Import function can be accessed via API as well as through the Marketo user interface. By default, the list import function can process two list imports at a time and can queue up to ten more. If the API has a large number of list imports queued up, this may interfere with your ability to import lists in your Marketo instance. If this occurs regularly, you may want to work with your IT department to schedule the API calls to run outside of business hours.

Issue Leads that qualify for a Smart Campaign run through the flow with a Change Data Value flow step, but some leads don't have a data value changed, while other flow steps still apply. It seems that those leads have just skipped the Change Data Value step and went right on to the next flow step. Solution If the new value for the Change Data Value is exactly the same as the current value in the lead record, Marketo will skip that flow step. There won't be an activity entry in the activity log or results tab because the action did not actually happen. Example Say you had a field called Favorite Sport and a lead that already has the value of "Football" in that field on their record. The flow step is Change Data Value: Attribute: Favorite Sport New Value: Football In this example, a lead will run that through flow step, but since the value did not change Marketo will just move on to the next flow step.

Issue How to identify in which campaign the "Delete Person" flow step is used. Solution You can identify it by going to "Campaign Inspector" in Marketing Activities. From there you can filter down by type of Smart Campaign and search "Delete Person" and the resulting list will be Smart Campaigns containing that flow step. If you do not see the Campaign Inspector, contact Marketo Support to have it enabled.

Issue Facebook Lead Ads was configured in a Sandbox subscription and then migrated to the Production subscription after testing was completed. After that swap, the Facebook Lead Ads integration is not passing records to the Production subscription. Solution Deleting the Facebook LaunchPoint service does not unregister it from the Facebook Lead Ad pages. To ensure that the Facebook Lead Ad pages is unregistered from the Sandbox subscription and successfully reconnects to the production subscription, perform the following steps: 1. Go into the sandbox and create (or Edit if it still exists) the Facebook LaunchPoint again (just leave the default settings for pages and fields). 2. Once created, go back into the Facebook LaunchPoint and UNSELECT all of the pages that are currently selected (You want to make sure no pages are selected at this point). 3. Save. By doing this you will be unregistering the Marketo endpoint from all the Facebook Lead Ad pages for the sandbox subscription. You can then delete the LaunchPoint if you wish from the Sandbox subscription. 4. Go into the production subscription, since the Facebook LaunchPoint service exists, go back in edit mode and select all the pages you want to leads to come from. 5. Save. This should be able to successfully select the Facebook Lead Ad pages and register them to the production subscription. 6. Test one of the Facebook Lead Ad pages and verify if the data syncs to the Production subscription.

Issue You have a tracked link in an email. When the email is received, the link breaks and doesn't redirect to the desired page. The link works perfectly when the tracking is disabled. Solution The server hosting the link might not accept parameters, or might limit the number of characters in the parameter, etc. When tracking is enabled, Marketo adds mkt_tok=manymanycharacters. The issue could be either the page does not accept parameters at all, or does not accept such long parameters. You might need to reach out to the developers of that page and investigate this. Our suggestion is to have “track link” checked but not the “Include mkt_tok”. Unchecking just Include mkt_tok will still allow the link to be tracked, but after redirect, the destination URL will not include the mkt_tok query string parameter.

Issue A Smart Campaign with a "Person is Created" trigger, in combination with additional filters, doesn't qualify people as expected. Solution Using filters with "Person is Created" triggers can cause issues when a person is created, but the values that the filters look for aren't filled in yet. When the Smart Campaign checks the filters, the data it looks for hasn't been filled in yet, so people don't qualify. Here are a couple alternatives: A scheduled batch campaign that looks for people who were created and meet those filters. Use the Person is Created trigger, but use a wait step to allow time for the date to fill in, followed by choices in the flow to qualify people.

Issue Choices are skipped in flow steps on campaigns triggered by new person creation when they are based on system managed fields such as Inferred State Region.. Solution Inferred Fields and other system managed fields my take a while to populate. When this happens, they won't have the necessary values at the moment the campaign is triggered. To resolve this, add a small wait step as the first step of the flow for trigger campaigns. This wait step allows the system to populate these fields and index them appropriately so they can be used as criteria in flow steps that have decisions in them.

Issue Issue Description You have IP login restrictions set up per documentation, but you're logged in via Single Sign-On (SSO) from an IP that isn't whitelisted, or is blacklisted. Solution Issue Resolution Marketo cannot enforce IP login restrictions on users accessing the instance via SSO. The IP Address restrictions are only enforced on users who login via login.marketo.com. Who This Solution Applies To SSO Users

Issue You created lists in SFDC and Marketo with identical filters/constraints for a field on the Opportunity Object, but the Marketo list is returning many more leads than the SFDC list. Solution The issue is due to Marketo field string values not being case-sensitive. Salesforce is case-sensitive, and will generate Opportunity IDs with the same letters, but with different capitalization arrangement. For example: In SFDC: "0060y000016PzXw" is a different Opportunity ID than "0060y000016PZxW" In Marketo, these two IDs are considered identical. As a result, Marketo will return leads that are not showing up on the Salesforce list. Adding the varied-case ID to the SFDC list filters will return the extra leads from Marketo. Smart List filters are not case-sensitive in Marketo, and will qualify leads with matching field values, regardless of letter case. One work-around option would be to use a 'Company Name' filter (or other known value) to further limit the leads in Marketo associated with the Opportunity. Who This Solution Applies To Customers synced to SFDC
