Included in this article Overview Data you’ll get from Email Bounces Bounce Categories Hard Bounces Soft Bounces Bounce Details Building the Directory 1. Create 6 custom fields 2. 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.

Article Text Included in this article Overview Include Pages Target URL Use Case Overview Target URL and Include Pages are both RTP terms that sound the same and get confused together, but they have different uses and meanings. This doc will go over what the differences between them are and how each can be used. Include Pages "Include Pages" is a filter used in Segments that will look for visitors who have been to specific pages. This filter will make the segment match for the visitor when they go to the designated page during the visitor’s session. If the visitor goes to one of the "Included Pages" during their session, then they match for the segment. Target URL "Target URL" is used in RTP Campaigns. In the campaign editor, the Target URL defines which page(s) the campaign will be displayed on. So, whenever the campaign is called by a segment, it will only be displayed on those pages specified in the Target URL area of the campaign. If the visitor is not viewing one of these specified pages, the campaign will not show. Use Case By using these together, you can create a campaign that will be displayed on your homepage (the Target URL) only if the visitor first viewed the pricing page (the Included Page). So, let's say your visitor went to the pricing page to look at Product A, then went back to your home page. You can have a campaign display info about Product A on your homepage knowing that the visitor is interested in that product already.

Issue -Error editing image in email: “image URL does not exist” or “image URL cannot be found” Environment -SSL not enabled on Marketo instance -Browser blocks unsecured content Solution Option 1 -Set up SSL for landing pages (Recommended! SSL should be a baseline configuration for all landing pages and tracking domains). Add SSL to Your Landing Pages | Adobe Marketo Engage Option 2 (Not recommended! Warning! This is a security risk.) -Allow browser to view unsecured content (can choose to turn this setting back off in the browser after viewing the content) This link below describes how to enable this content in Chrome. https://docs.adobe.com/content/help/en/target/using/experiences/vec/troubleshoot-composer/mixed-content.html This link below describes how to enable this content in Firefox. https://support.mozilla.org/en-US/kb/mixed-content-blocking-firefox Option 3 -Try to use a different browser or try turning off all browser extensions. Root Cause This issue could be caused by SSL not being enabled. If the issue was sudden, and SSL is enabled, it is likely due to the browser needing an update. Check if there are any updates that need to be done.

Issue Issue Description You have a record with a "Change Data Value" activity, but that field doesn't have a value on the current record. There's also an anonymous lead merge (which can be identified by looking for a Merge Leads activity and seeing if "Anonymous Source" is True) on the record. Solution Issue Resolution Check the Change Data Value's "LeadId" field. If this matches the anonymous record's ID (identified from the Merge Leads activity in the "Merge Id" field), then the reason for the value not showing is because upon association of an anonymous lead to a known record, only the activities are merged -- not the values of any fields which may have been recorded as changed.

Issue The standard unsubscribe footer shown in Admin > Email is not being appended to a particular email. Solution Issue Resolution This can happen when an email contains the system token unsubscribe link: {{system.unsubscribeLink}} When an email contains this token, Marketo does not automatically append the unsubscribe HTML snippet, found at Admin > Email > Unsubscribe HTML. Check the HTML of the email asset with this behavior. Search the text version of the email. You may find the {{system.unsubscribeLink}} in the template you are using. If you have searched the HTML of the email, and are not seeing the system token, contact Marketo Support.

Issue You are unable to archive or delete an asset in Marketo. When you try to do so, you get an error: "The following assets are in use or used by other assets." Solution To archive or delete the asset, you will need to determine where it is being used. Click the Used By tab for the asset you are trying to delete and see what other assets reference it in some way. For instance, aSmart Campaign may be using it in the Smart List or the Flow Steps, or a report might have it in the Smart List. Once you find where your asset is being used, you can go and remove references to it from the other assets. This should allow you to delete or archive it.

Included in this Article: Overview Checking for Segment Matches Reasons for not Matching Typos Non-exact Matches Overview Using segments, you can target specific organizations by using the Named Accounts attribute in the segment editor. With this attribute, you can select all organizations in a Named Account List or by manually selecting organizations. However sometimes we see one of those organizations visiting the website but it doesn't match the segment, even though it is included in the segment list. Checking for Segment Matches If a list was created manually, it's possible the organization wasn't included in the segment list in the first place. To check: Go to the Organizations tab Use the search bar to search the name of the organization in question If the organization was entered in the list correctly, it will be found through the search. If it does not appear in the search results, there are two issues that are likely to have arisen. Reasons for not Matching Typos Luckily, typos are easy to fix. Simply edit the organization's name to match the spelling you wanted it to take on. Non-exact Matches Even if an organization is spelled correctly, it will still not match the organization listed in the segment if the names aren't exactly the same. It is very common for companies to have different names for their organization. To fix these non-exact matches, you'll have to be clever about how you name your organizations. In RTP, an important character to know is the wildcard character, represented by an asterisk (*). A wildcard character will match with any character or sequence of characters For example, the string "Salesforce*" will match all three of the above spellings ("Salesforce.com", "Salesforce.com Inc.", and "Salesforce Ltd") because they all begin with "Salesforce". For more examples on how to use wildcard characters, follow this document: RTP Glossary - Marketo Docs However, you must be careful using wildcards characters, because you could potentially match organizations that you didn't intend to match. For instance, the string "Salesforce*" will not only match the three examples above, but also a company named "Salesforce Finance", a completely different company.

Issue The count for the audience of an Email blast program does not match the total members of the Email Program after it has been executed. Environment This issue is applicable to users who have recently run an Email blast program in Marketo. Solution The disparity in numbers occurs because the Audience Smart List is evaluated at the moment you access it. As your records evolve, this number can change after the Email Program is run. In contrast, the number of program members, who are the recipients that were emailed through the program during the scheduled run, is fixed at the point the program is executed.

Issue Issue Description Possible disadvantages of maintaining Engagement/Nurture Program emails in Design Studio. Solution Issue Resolution Housing all of your emails for email nurture content in Design Studio could cause the following issues: 1. Reporting: Reports can specify Emails in Design Studio, however they will show results for any send of the individual email and will not be constricted to the program they were sent from. 2. Asset re-use in Engagement Programs: When using an engagement program, an asset is scanned for its ID. If that asset has been previously sent to a record via any other send, the engagement program will skip that send for that record. This could become a problem when reusing email assets housed in design studio in different engagement programs. 3. My Tokens: my.tokens will not properly render as they are based on a program folder. The assets that reference them need to be in the folder as well. In my testing, assets in design studio do not have a frame of reference for mytokens. Emails will not populate mytokens if they are housed outside of the program that owns the tokens. With all of this noted, our recommendation is to utilize detailed templates in design studio and continue to clone your engagement programs and alter them as necessary. Although this presents some busy work in the short term, it pays off dividends in the long term when it comes to reporting, the use of my.tokens, and guaranteeing that records are sent the assets you are specifying in your programs.

Issue Issue Description Even though the Success Path Analyzer and the RCE report may be looking at the same thing (e.g the conversions from one stage to another), the numbers in Success Path Analyzer and RCE Conversion Ratio will not match. Solution Issue Resolution Success Path Analyzer is telling you that records are flowing from one stage to another, for example a record moving from Cold List to MQL, the conversion rate will display the rate from this stage to the next stage. If you look at the RCE Conversion Ratio, this is not tracking just the conversion from the first stage on the Success Path Analyzer to the second but instead this tracks all the conversions from this stage to another (eg. Cold List to MQL, Cold List to Attempting). Thus resulting in a much higher conversion percentage as the RCE is not bound to the green path from the Success Path Analyzer. Who This Solution Applies To Customers using RCE, Customers using Success Path Analyzer

Issue Reporting on separate links in an email that both point to the same URL Solution When there are duplicate links in an email, the performance of those links will be consolidated into a single row in the Analytics report, so if there are three links that point to the same URL, there will only be a single line for that link on the Performance report. If you would like to differentiate between these duplicates, you can add URL Parameters. Example: www.google.com and www.google.com?parameter=second-link In this example, Marketo Link Performance Reporting will show each individual link on Analytics Reporting, but both links will go to the same place.

Processing feedback from the blocklists is a manual process for Marketo’s Compliance team. While we try to get the reports out to you on a daily basis, sometimes we get backlogged and notifications may not go out the same day that you triggered the blocklist. But not to worry: most blocklists are dynamic, meaning that they resolve themselves after a given time period or when email statistics improve. Typically blocklist issues are resolved after 24 hours, so chances are you are not still being blocklisted. Still, you need to complete the blocklist remediation program to identify the source of the problem and ensure that this doesn’t happen again. While most blocklist issues resolve themselves, they can have a noticeable impact on deliverability. Furthermore, being blocklisted is an indication that you have a problematic data source in your lists that could lead to even bigger deliverability problems. For a quick run down of the blocklists that our customers run into trouble with the most, visit our Top Blocklists article.

Issue Why is there a difference between the Exhausted Count displayed in an Engagement Program Stream vs. a smart list using the "member of engagement program stream is exhausted" filter? Solution To account for the difference in a smart list that is displaying a different number of people that have exhausted the content in a stream, in the smart list account for the other conditions the Exhausted Count uses: Engagement Program Cadence of "normal" - this can be included as a constraint on the "Member of Engagement Program" smart list filter The members were not blocked - this can be included in the smart list by using the smart list filters: member of smart list is not blocklisted, unsubscribed = false, marketing suspended = false, email address is not empty and/or email invalid is false. Have not exceeded the communication limit at the last nurture cast - there is no specific smart list filter for this, so it will need to be manually checked in a lead's activity log. Root Cause The Exhausted Count represents the latest exhausted number after the last run/cast. It has other conditions like the nurture cadence of a member should be "Normal", and the member was not blocked or have not exceeded the communication limit at the last nurture cast. If the smart list is configured as follows, then it will display a different number as it does not account for the engagement program cadence of 'Normal' and if a member is not blocked and has not exceeded the communication limit at the last nurture cast. #1: Member of Engagement Program is any Exhausted Content is true Program is [Program Name] Stream is [Stream Name] Environment Engagement Program Exhausted Content Smart List

Issue Issue Description User has 'Delete Marketing Asset' permission in Marketing Activities but is unable to delete a Smart List. The Limited Access message below is being returned: "You do not have sufficient privileges to perform this action" Solution Issue Resolution In order for a user to have permission to delete a Smart List in Marketing Activities, the user would need to have access to Marketing Activities and have the 'Delete List' permission. see article for list of permissions: http://docs.marketo.com/display/public/DOCS/Descriptions+of+Role+Permissions

Issue You have run a Smart Campaign with a single flow step, Change Data Value, and you do not see the entire campaign membership in the Results Tab. Solution If the Flow step is changing an attribute to a given value ("example value"), but a lead record that qualified for the campaign already has that value ("example value") in the field, there will be no change and the record will not display in the Results tab. Since the record already has the value, Marketo will not write another change on the activity log and so the record will not show in the Results Tab.

Issue You put a variable inside an email token and when the email was sent, the variable rendered as text rather than as a link: Example: ${queryParameters} Should expand to: {{my.CertainURLHREF}}?utm_source=${utm-source}&utm_content=${utm-content}&utm_medium=${utm-medium}&utm_campaign=${utm-campaign}&ajs_uid={{lead.Email Address}}&ajs_event=Email%20Clicked With the various tokens populated Instead it expands to this: https://app.fakewebsite.biz/profile/55555555?utm_source=$%7Butm-source%7D&utm_content=$%7Butm-content%7D&utm_medium=$%7Butm-medium%7D&utm_campaign=$%7Butm-campaign%7D&ajs_uid=adam.tow+test@voxmedia.com&ajs_event=Email%20Clicked Solution Essentially, email template variables are used at design time to make building out an email easier. Tokens are used at send time to make data variable per program without having to edit the asset or lead. Putting email template variables inside tokens won't work for this reason. It is just how the current design works and you will not be able to put email template tokens inside my tokens or lead tokens. Unwrapping variables before you put them within the token will allow them to function properly. This removes the simplicity of the variable, but retains the functionality.

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.
