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

Issue Clicking on a link in a Marketo e-mail that re-directs to a non-Marketo webpage destination does not open the page. Solution Complete the troubleshooting step below. If they do not resolve the issue, include the results in a Marketo Support Ticket. Check the CNAME is correctly setup for the email tracking link Check that the Default Branding Name matches the CNAME in Step 1 (check for typos). If you are unsure you can visit CNAME lookup on mxtoolbox and enter the default branding name to check. Under the Domain field enter your default branding name. Do you have SSL for tracking links enabled? If Yes, tracking links in emails should start with HTTPS:// If No, tracking links in emails should start with HTTP:// If you do not have SSL enabled, but when you click the link it resolves to HTTPS://,try a different network and see if it still occurs. Your network may be configured to automatically use HTTPS automatically even if the link is specified as HTTP. (Check with your network admin) If you are re-directed to the non-Marketo landing page but the page does not load: Check with the website admin if there are any redirect rules setup on the website. Try cutting out parts of the additional URL Parameter to see if that fixes the issue to identify which part of the URL parameter is causing it. Sometimes lead tokens or the mkt_tok may affect a redirect rule, since mkt_tok generates random characters and sometimes the token contains percentage '%' characters. It very common for websites to interpret a % followed by a character as an encoding. Seen in this website here If you are unable to resolve the issue in the steps above, provide the test results and information in a Marketo Support Case.

Issue Issue Description The user role has all the permissions to Design Studio, but whenever trying to preview an email, a limited access message is displayed: "You do not have sufficient privileges to perform this action" This is a article attached image Solution Issue Resolution The user role must have permission to 'Access Database'. The full access to Database is not needed, just the main access by selecting 'Access Database' and unchecking everything else underneath. The reason for this permission is that, when previewing emails, you are able to select to preview an email as a specific lead. In order for this to happen, users will need access to leads.

Issue You would like an links in an email to be tracked, but need to eliminate the tracking URL parameter on the tracked links. Solution In the Email Editor, you can uncheck "include mkt_tok" in the Edit Link box. This is a article attached image Adding a class "mktNoTok" to any Anchor Tag will allow you to keep the Link Tracking, but disable the Tracking Token Parameter from the URL. You may also edit the Head of the email HTML to make large sections with this class.

Question: How do I add a link to my lead/contact's Salesforce detail page when sending an alert from Marketo? Answer: If the lead or contact is in both Marketo and Salesforce at the time when the alert email is sent, then the link to the Salesforce detail page will be automatically appended to the alert email sent by Marketo. Note You will need to use the "Send Alert Info" token within your Alert email while designing your email in the Design Studio of Marketo. This is a article attached image Below is what the generated alert looks like once it is sent from Marketo (note the link to the Salesforce detail page is automatically inserted): This is a article attached image Note if the lead or contact is not in Salesforce then there is no link to the Salesforce detail page: This is a article attached image

Issue Clicking "Automatically copy over from HTML" or "Copy from HTML" in the Email Editor fails to copy the contents over to the Text Only version of the email. Solution This can occur if there are no editable sections in the email asset. Only in editable sections of an email will be copied over to the Text version of an email. Here is additional documentation: https://experienceleague.adobe.com/docs/marketo/using/product-docs/email-marketing/general/creating-an-email/edit-the-text-version-of-an-email.html?lang=en A quick workaround would be to manually copy and paste the content you wish in the Text Version, and in the future build/use templates to make emails with editable sections.

Question: I have leads that are getting created without providing information for fields which I have made required. Answer: Marketo's field validation makes use of javascript. Most browsers have javascript enabled by default so this should be fairly rare, but a user could change their settings and turn javascript off. This would allow them to submit a form without providing all the required information. This situation may also occur if a lead submits the first progressive profiling form and subsequently submits a second form with different questions, while also changing the email address (indicating either a different person using the same PC or the same person with two email addresses). Marketo will generate a new lead record, but it won't include the data captured in the first form. To identify if this is the case, examine the "Fills Out Form" activity and check if there is data submitted from a later progressive profile form. If so, this is likely the cause. To address this issue, follow these steps: Create a smart list with an Anonymous IP filter. Enter the anonymous IP address of the lead. The smart list may identify multiple records associated with the anonymous IP address. Merge or manually update the records as needed based on the identified information. By following these steps, you can reconcile the data and ensure that the lead records are appropriately managed.

Issue When you click on ‘Forward to Friend’ link on an email template, it redirects you to the below 404 error page. This is a article attached image Solution The ‘Forward to Friend’ link will work only in a sent email and not on an email template. To test this functionality, you need to create an email using the template which contains "Forward to Friend’ link and then send the email to your test lead using a run action. It will not work properly with a send sample. Open the email and click on the "Forward to Friend" link. Once clicked the email will open on a webpage and then the below "Forward to Friend" box will be visible. This is a article attached image To know more about "Forward to Friend", refer the below document. http://docs.marketo.com/display/public/DOCS/%27Forward+to+a+Friend+Link%27+in+Emails

Issue You have Visibility Rules enabled for a field on your form, but the field is not shown or hidden as expected based on the values in the other fields. Solution If you have enabled visibility rules for Field B but the field is not showing/hiding as expected when the correct value is chosen in Field A, one possibility could be the with the setup with the selected operator in the rule. When using visibility rules for Field B, the "is" operator will use and reference the displayed values of Field A, but "contains" will use the stored values. For example, let's say you have a visibility rule that should display the a particular field when 'Marketo Lead Management' is selected for the "Product Interest" field. The displayed value for the field (the one shown to the customer) may be "Marketo Leads Management" but the stored value for the field (the value written to the lead record) is "MLM". If you set up the visibility rule as "Product Interest is Marketo Leads Management", the rule will look at the Display Value and see a match. However, "Product Interest contains Marketo Leads Management" will look at the Stored Value, which is "MLM." It will not see the match, and the field will not be displayed.

Issue: When I try to approve an email I get the following error: Error approving Email Name - Sending IP is empty or not valid This is a article attached image Solution: You likely have multiple dedicated IPs and you did not choose which one to send this email from. 1. Edit Draft of the email in question. 2. Select which IP Address you want this email to sent from and click Save. This is a article attached image 3. Close the email editor and under Email Actions click on Approve.

Issue Embedded Marketo form not visible in Firefox Private Browsing mode. Solution Firefox's private mode will be enabled by default. When you embed a Marketo form in your own webpages and view it in Firefox's private mode, it will disable the Javascript as part of the tracking protection of this browser. JavaScript is needed for the forms to appear on the landing pages or webpages. The "Tracking Protection" in the Firefox browser will need to be deactivated for the form to appear. Here is an article from FireFox regarding the Tracking Protection: https://support.mozilla.org/en-US/kb/tracking-protection

Issue Marketo forms that are embedded on external web pages see loading errors. Examples of this could be that the fields load with delay, or once submitted the form lags before moving to a follow up page. Solution Two things to check: Is there custom CSS in your form? Is the embed code on your form customized? Isolate the cause You can isolate the root of the lag by testing your form on a Marketo Landing Page 1. Locate the embedded form with in your instance 2. Build a landing page to test the form: Landing Page with a Form 3. Place your form on the new testing landing page, approve the page and close it. 4. Load the Landing Page using the URL If the form loads with no delay, the issue lies with the embed code used to push the form onto the external page. Please work with your custom developer to find a resolution. If the form is loading with a delay (and there is custom CSS): 1. Clone your form 2. Remove any custom CSS from with in the form 3. Build a landing page to test the form: Landing Page with a Form 4. Place your form on the new testing landing page, approve the page and close it. 5. Load the Landing Page using the URL If you are not seeing any loading errors, the issue lies with in the custom CSS of your form. Please work with your custom coder to improve the loading speed of your form. Note: Occasionally, incorporating the form embed script into containers (custom coding) and utilizing custom JavaScript may lead to delays in form functionality. In such instances, it is recommended to collaborate with your developer to identify a solution, as Marketo Support does not troubleshoot issues specifically related to custom coding. If you are still seeing lag errors on your form loading on the Marketo Page, please submit a ticket with support@marketo.com

Issue Email won't be approved due to too many custom tokens Solution Sometimes when approving an email with a large number of of tokens, the following error message will appear: 'The number of custom tokens in the email exceeds the limit ' This is a article attached image This means that you have too many custom tokens in the email and that if you wish to approve the email, you will need to remove one or more of your custom tokens in the email. Its important to note that this only applies to custom tokens, which are tokens based on a custom field in Marketo. This means that while you will be allowed to add more of the standard tokens to the email and approve it, you will not be allowed to go beyond the 40 custom token limit we have in place for the non-standard tokens. Here you will find all the standard tokens in Marketo

Issue The same email looks different in different email clients, and does not match what is shown in the Email Previewer. Solution Different browsers and email clients render HTML and CSS differently. While there are standards set forth by W3C, there is room for flexibility. At a high level, it is expected for emails to look different, even within the same platform such as Outlook 2013 vs Outlook 2010. With that said, you can code against some of these anomalies by adding extra code in CSS to account for the differences. You should consult with an HTML/CSS designer to make these changes. In all likelihood, the issue is related to how Outlook(or any other email client) is rendering the email and reviewing the Outlook settings as well as email and template code should resolve any issues customers are experiencing as when we send test emails to both outlook and gmail both are generally rendered differently (gmail seems a bit fine though). FAQs Where should I start trying to determine whether this is a Marketo or Outlook issue? In most cases if the email is loading within another email client without issue then Outlook would be the best location to review. Is there a way for me to see if it is a template problem? Yes, does the issue occur when an email is created and sent with another template? What are the steps to troubleshoot? In general, to provide the most accurate troubleshooting steps, a bit more information will be helpful. I have provided a few general tips below which may be helpful. As a rule of thumb, Outlook sometimes requires custom coding to appear as it does in other email clients since they use their own word engine to render the html. If the images when they are downloaded are not displaying as expected, we would typically recommend reviewing any code in the email since Outlook uses its word engine to render html and additional code may be needed for Outlook specifically as a result. A developer may be required to implement any custom code required to display the emails as expected. You may consider reaching out to the Community to understand what other users have done to overcome similar obstacles. I have provided a few links below which may be relevant.

Issue Email asset does not show which template it was built on and shows the word "none" instead of the name of the template that was used to create that asset. Solution Any edit directly to the HTML code of an email will break the connection between the email and the template. Changes made to the template will no longer flow down to the email. After making those change you will see a template name of None instead of the name of a template. When editing the HTML in the email, you will see this warning message: This is a article attached image

What is the Email API? What is the Email API used for? What is Email 2.0? Does the Email API Work on Email 2.0 Assets? Will the Email API Break when Enabling Email Experience 2.0? How Are 1.0 Assets Upgraded to 2.0 Assets? What to Do When an Email Was Accidentally Converted to Email 2.0 format? What is the Email API? API stands for Application Programming Interface and the Email API allows an automated process to create and edit emails in Marketo. There are also other API calls that involve emails, such as Approve Snippet (assuming the Snippet is used in an Email) and Clone Program (assuming the Program contains Emails). There are also API calls to create and update Email Templates. Essentially, the API can do many things that you can also do through the Marketo user interface, but then in an automated fashion. What is the Email API used for? There are many scenarios: an external system could create Emails in Marketo using data that lives outside of Marketo. A translation service provider could clone a master Email, translate it to many languages, then save them back into Marketo as localized Emails. A reporting system could extract Emails from Marketo to use in reports that are generated outside of Marketo. An external system could Clone a Program that contains Emails, then populate the Program Tokens and schedule the Email to be sent out at a specific time. There could be an external email template creation system that creates new Email templates in Marketo through the API. What is Email 2.0? “Email Experience 2.0” is the new Marketo product feature with the enhanced email editor, documented here: https://docs.marketo.com/display/public/DOCS/Email+Editor+v2.0+Overview. It can be switched on in Admin > Email > Edit Email Editor Settings. All Emails and Email Templates also have a version number, either 1.0 (the old version) or 2.0 (the new version). If we refer to “Email 2.0 asset” we mean an email or email template in the new upgraded 2.0 format. Does the Email API Work on Email 2.0 Assets? Yes. Will the Email API Break when Enabling Email Experience 2.0? No. Enabling Email 2.0 will not automatically upgrade Emails or Email Templates to the new 2.0 format. The Email API can still create new Emails and Email Templates in the 1.0 format. However – after enabling Email 2.0 – any Email or Email Template that is created or edited and approved through the Marketo User Interface will automatically be upgraded to the 2.0 format. How Are 1.0 Assets Upgraded to 2.0 Assets? If you edit an “Approved" or “Approved with Draft” 1.0 Email with Email 2.0 enabled, the draft is converted to the 2.0 format. You can still discard the draft to go back to the approved 1.0 format. Once you approve the email and it becomes 2.0, the Email cannot be converted back to 1.0. If you edit a “Draft” 1.0 Email (never been approved), this will automatically be converted to 2.0 with no option to revert back to the 1.0 format. The same applies to Email Templates. What to Do When an Email Was Accidentally Converted to Email 2.0 format? If an Email or Email Template was accidentally converted to the 2.0 format, you’d have to copy the asset contents to a text editor, disable Email 2.0, then create a new 1.0 asset using the content that you copied.

Issue You have been receiving form submissions that appear to have bogus/nonsensical data in the fields, such as "kjsag@sm4.to" for email address, or "111-111-1111" for phone number, or in a Comment field other random nonsensical text. Solution Currently, there are no default settings in Marketo that prohibit a form submission if the required fields are filled out. A great workaround for addressing these bogus form submissions in Marketo is to implement a 'honeypot' field on the form. To do this, you will need to create a custom Marketo field, string type, and name it something distinctive (such as "spam" or "honeypot"). After creating this field in Marketo Admin > Field Management, place this new field on the form as a hidden field. Real live end-users do not see hidden fields, but spam bots will see them and fill out all available fields. So now when we see form fills with this honeypot field "not empty," we know that it was a bot fillout. Setting up the Honeypot Field Say that you have a Trigger Campaign that's having some issue with these spam/bogus form fills. In the flow of this campaign, you can add a flow step at the top: Remove from Flow, with a Choice. Choice: If Honeypot field Is not empty, then remove from flow Default: do nothing This way, the lead record is removed from the flow. You can also have other campaigns to handle these bogus form fills, such as a daily recurring batch to delete the record. Other Options Another method of dealing with bot fillouts is to enable a reCaptcha. In fact, a very prolific Marketo user has written custom code that you feasibly could use to enable a reCaptcha on the form! Check this out: https://codepen.io/figureone/pen/meybqN?editors=0110

Issue You want to have one email address in the From field ( abc@test.com) a different email address in the Reply-To (all@test.com)? Solution Yes, you can use different email addresses in the From and Reply-To. If the Reply-To is an email alias that sends to a group, you should confirm that email is working and able to receive email. Please note: Automatic replies, such as out-of-office notifications will be sent to the From address, not the Reply-To. Reply-To is only used when the person who received the email clicks the Reply button in their email client. Note :- The SMTP envelope sender typically appears as <uniqueidentifier>@*.mktomail.com. You will only receive responses of this nature if you have configured a branded sender for your subscription. While this serves as the correct destination for auto-responses, regrettably, it is frequently overlooked.

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 -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.
