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.

Issue: After changing your email template, your associated emails are now blank or the main template is showing. Why does this happen? This happens because the editor cannot associate the unique "mktedtable" divs from the template to the email. When creating a template, each section that can be changed will have a class of "mktEditable" and a unique "ID". <div class=”mktEditable” id=”1body”> your editable content</div> Solution: To fix your current emails, preview the current approved email and verify there is infact content. 1.discard draft 2.edit draft, it will still look blank until step 3 is complete 3.replace html with no changes, the html content should show again. 4.approve the email Don't change anything and click OK. Your orginal email content will be restored. Caution: This only works if you did not approve the email when it was blank. Note about the blank "template": When using the blank template in general, it means you intend to address your email at the main email level. Adding style to the blank template invalidates it as a blank template. The best practice would be to create a new template and add your custom code.

Issue Description There is a discrepancy for certain emails between Email Insights and Email Performance Report. The data (e.g. sent, delivered, opened and clicked) are significantly lower in Email Insights for the emails as compared to the Email Performance Report for the same emails. Issue Resolution There is most likely a discrepancy because at the time Email Insights was first enabled "you’ll have four weeks of historical Email data in addition to all new email activity". There was no request to Marketo support to upload historic data beyond four weeks which would have included data for the emails above. This request relates to the notes below from the article: "We’ll give you a four-week period before you can request Marketo Support to upload your data" Supplement: Email Insights Launch Process - Marketo Docs - Product Documentation The solution is to request that Marketo Support backfill the report data so you have data for Email Insights beyond the four weeks.

If you are encountering issues with importing to certain fields, it is recommended that you create an import template. To make sure your field names are correct for an import, start by exporting a small list from your lead database. You can selected your required fields via the column chooser by right clicking a field in your list. Then select Export list under List Actions, then select Visible columns or All columns in your export. In the exported .csv file check the first row; your correctly named fields should be listed in there. You can now copy the field names to your import list, or copy the cells from your list to this exported .csv. You should now be able to import without issue. Please note: if you select All columns then the exported .csv file contains system fields that cannot be re-imported to. Please see the related article: Ignored Fields and Blocked Field Updates During List Import

Issue: You or your sales reps are getting an error when editing your leads or contact records in Salesforce saying "The record you were editing was modified by Account Marketo during your edit session". Similar to this: This error will usually occur in Salesforce when you are in the Edit page in while at the same time the Marketo sync is updating that same record by our periodic API sync. While this error occurs very rarely, and usually by performing mass updates from Marketo (usually by batch campaigns). Resolution: Here are some steps you can take from a Marketo perspective to resolve or significantly reduce the chances of this error occuring: 1. Change the process that you use to update records in Salesforce - You can successfully reduce this error by using Inline editting (by double clicking on the individual field on the record) as opposed to doing a mass update of multiple fields on 1 record (by using the Edit button). Inline Editing - As the screenshot below shows, this done by double clicking on the individual field on your record then updating the field and then pressing the "Save" button or double pressing on the Enter key on your keyboard: Mass Editing - this is done by first pressing the "Edit" button on the record's detail page, which will then take you the the Edit page where you can mass update multiple records then press the "Save" button: 2. Increase the Salesforce sync interval time - Another option to reduce the the possibility or receiving this error is to reduce the number of times that Marketo syncs with Salesforce. This option in effect increases the time between Marketo and salesforce syncs. (The default is 5 minutes.) The downside to this option is that updates made in Marketo will take a longer to sync to Salesforce and vice versa. If you want to proceed with this option, you will need to contact Marketo support to get your sync wait time increased.

Starting with the September 24, 2011 release of Marketo, Programs must have an associated cost in order for them to show up in the analyzer. If you want a no-cost program to show up RCA, then it must have a zero cost created in the setup. 1. Go to Programs and select Setup 2. Drag in a cost and add 0 (zero) 3. Save the changes You should now be able to see your Programs in the Analyzers. "Only programs that have cost will show up in RCA reports."

To customize the validation message, you can add javascript to the template of the landing page the form is on. Unlike default language settings on a form, customized messages work only on landing pages using the modified template. Note: Please ensure that you have access to an experienced Web developer. Marketo Technical Support is not set up to assist with troubleshooting code. Open up your landing page template for editing. For all languages you wish to modify, paste this javascript code (with your modifications) at the end of your template before the </body> tag. For more languages, see this javascript file. <script type="text/javascript"> Mkto.messages = { English : { required : "This field is required", selectRequired : "Please select a value for this field", emailInvalid : "Please enter a valid email address", telephoneInvalid : "Please enter a valid telephone number", pleaseWait : "Please wait" }, French : { required : "Ce champ est requis", selectRequired : "Sélectionnez une valeur pour ce champ", emailInvalid : "Entrez une adresse e-mail valide", telephoneInvalid : "Entrez un numéro de téléphone valide", pleaseWait : "Veuillez patienter" }, German : { required : "Dieses Feld ist erforderlich", selectRequired : "Wählen Sie einen Wert für dieses Feld", emailInvalid : "Geben Sie eine gültige E-Mail-Adresse ein", telephoneInvalid : "Geben Sie eine gültige Telefonnummer ein", pleaseWait : "Bitte warten" } }; </script> Tip: You can include multiple languages in a single template. The language selection on the form will determine the language that gets shown.

Issue: You want to make the label of the form appear inside the input field. Solution: Use the below code in a custom html block on a landing page with a form: remove the current labels in the form editor place the complete code (attached) in a custom html block on the page with the form View the live page to the see the changes This code uses the field "id" you could use "name" instead. This does not work for "select" fields Note: Please ensure that you have access to an experienced JavaScript developer. Marketo Technical Support is not set up to assist with troubleshooting JavaScript. Please refer to the example and source: http://trevordavis.net/play/jquery-inline-form-labels/

Sometimes you may see a link in your email that isn't decorated when you mouse over it. That same link isn't tracked when you click it. Check that there is a link The most common solution is to add a link to the email. Many email clients will automatically add links to when the text looks like a URL. For example, here's a link as it was typed in an email: But Outlook renders that text as a link: To fix this, edit the email and add a link to the URL by highlighting the text and clicking the link icon in the HTML editor: Check the <a> tag If you edited the HTML, check to make sure it's correct. Check if the: href is enclosed with quotes <a> is opened and closed correctly Check for class="mktNoTrack" If you edited the link with class="mktNoTrack", the link will not be decorated by Marketo. You'll have to remove that class from the email template or email body, depending on where it is. Validate your email HTML As an additional check, you might want to run the HTML through a validator; HTML errors can cause links to break among other problems. Download the HTML for your email with the Download HTML button in the HTML Tools menu. Then run the HTML through HTML Tidy. You should address the issues it discovers as they may be responsible for the bad link.

Warning: This isn't for the faint of heart. If you really know your Javascript and are comfortable with your landing pages, then you might consider adding custom validation on top of Marketo's built-in validation: Adding custom validation to a Marketo form before submitting it The function Mkto.validateField processes the form fields and checks their values. By changing that function, you can replace or remove Marketo's built-in form validation. Note: Please ensure that you have access to an experienced JavaScript developer. Marketo Technical Support is not set up to assist with troubleshooting JavaScript. Disabling Validation To disable Javascript validation outright, add this javascript to your landing page as a Custom HTML block or on your landing page template: <script type="text/javascript"> Mkto.validateField = function(fld) { return true; } </script> Custom Validation If you want to do your own validation, open http://appl.marketo.com/js/mktFormSupport.jsand find the Mkto.validateField function. It does lots of validation including email addresses, required fields, and phone numbers. If you want to do your own validating instead of Marketo's, replace the Mkto.validate function by using a dedicated Custom HTML block or by editing your landing page template: <script type="text/javascript"> Mkto.validateField = function(fld) { // code goes here. return true if it's valid, false otherwise return true; } </script> Instead, you really should keep the Marketo validation and instead add your own custom validation on top of that: Adding custom validation to a Marketo form before submitting it

Issue Description Email Insights does not display any data or metrics for specific program when the emails in the program are operational. Issue Resolution Operational emails are hidden by default, so no data or metrics will be shown in Email Insights unless 'Operational Emails' are included "Does Email Insights support Operational emails? Yes. By default, Operational emails are hidden from view and querying. However, you may change this setting under the Personal Settings panel." https://docs.marketo.com/display/public/DOCS/Email+Insights+FAQ Who This Solution Applies To Customers using Email Insights Is this article helpful ? YesNo

Issue: I added a link to an external page in one of my emails, when I receive the email and click on the link, it appears to be broken, but I am sure the URL is correct. Solution: Marketo adds code to links in emails as we send them out to track clicks. If the destination page is one that does not support URL parameters, the page may not load. This is very rare but in the case that it happens in your testing, you can try disabling tracking for that specific link. See Disable Tracking for an Email Link for detailed instructions.

Use sample if you want to place a label above a group of form fields. Here's an example of the result: Note: Please ensure that you have access to an experienced JavaScript developer. Marketo Technical Support is not set up to assist with troubleshooting JavaScript. In that example, if you wanted to add the label above the "First Name" and "Company Name" fields, you need to first get the IDs of those fields. After you have the ID(s), change the highlighted code below to those IDs. You can then change the style or text in the label by editing the HTML in the "before()" function. <script type="text/javascript" src="/js/public/jquery-latest.min.js"></script> <script type="text/javascript"> $jQ = jQuery.noConflict(); $jQ(document).ready(function(){ $jQ("#FirstName").parent().parent().before("<div style='padding-bottom:20px;font-weight:bold;'>Personal Info</div>"); $jQ("#Company").parent().parent().before("<div style='padding-bottom:20px;font-weight:bold;'>Company Info</div>"); }); </script> Download Attachments: Label above form fields-JS.txt

The email template shows in the preview window. 3. Click HTML Source. 4. Scroll to where your current mailing address is located (usually at the bottom) and update the information. 5 Click Preview to view your changes. Validate your changes. 6. Click Save and Close. 7. Approve your draft. 8. Click Emails from the tree on the left side of your screen. 9. Any emails that use the updated template will need to be re-approved. 10. You can approve the affected emails in this view (shown in the screen shot above) by highlighting the email(s) and choosing Email Actions > Approve Draft.

Issue: You would like have leads rate content (for example) and need the buttons to display horizontally. Please ensure that you have access to an experienced Web developer. Marketo Technical Support is not set up to assist with troubleshooting code. Solution: The buttons are laid out in a table format so adjusting margins and padding doesn't seem to do the trick, use CSS instead. Add the following to a custom HTML block: <style> tr {float:left;} </style> Disclaimer: This solution does not work for IE7 as it does not support the Float property correctly, this solution was tested in FF 5 and IE8/9 .

When a customer triggers a blacklisting on Marketo's shared IP range that customer is moved to a set of IPs we call the quarantined IP range. We do this to protect the health of our shared network and ensure the best deliverability possible for all of our customers on that network. If you have received a Blocklist Notification from Marketo reporting that you have triggered a blocklisting your Marketo account is now in the quarantined IP range. While you are in the quarantined range it is possible that you may experience a slight decrease in your deliverability rates. The reason for this is that you are now sending from a range made up of senders that have also caused other blocklist issues. All customers have received a notice of the listing and are in the process of repairing their database. There are two ways to be removed from the quarantined IP range: Follow the steps outlined in our Blocklist Remediation article. Be sure to fill out the form referenced in the email alert to indicate that you have taken steps to mitigate the issue. Demonstrate clean sending behavior for 3 months. We remove senders from the quarantined IP range if they have not triggered any new listings in 3 months. To ensure your best deliverability rates blocklist issues should be addressed right away to prevent further damage to your sending reputation. Furthermore, if no action is taken to improve list hygiene the issue will likely recur. Marketo's Privacy Team strongly recommend following the Blocklist Remediation steps.
