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 You attempt to approve an asset and receive a "Cannot update a stale object" error. Solution This error means that a newer version of the asset exists than the one you started with. This occurs most often with large teams or if you edit an asset in multiple tabs. When you edit an asset, it creates a draft. Another attempt to edit the asset while the previous draft is open would create a new draft, which then causes your first draft to become "stale." Refreshing your screen should resolve this issue and allow you to approve the asset.

Issue 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. Solution 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" The solution is to request that Marketo Support backfill the report data so you have data for Email Insights beyond the four weeks.

Issue You need to filter leads who were sent an email by time zone to confirm the Recipient Time Zone feature is working correctly for all leads. Solution The "Was Sent Email" and "Opened Email" filters do include the constraint "Date of Activity" but it is not that granular. You can get granular to the minutes, but you can only select "in past: 5 minutes" for example, not a specific time or date range. One workaround would be to View Results for the Email Program and filter for the "Send Email" activity. You could export the results to a spreadsheet to make sure people are being sent emails at the correct time.

Issue You want to create a field that will grab the web page the form was filled out on and add this as a token in an alert that goes to sales when a form is filled out. Solution This can be achieved either through a Smart Campaign or the JS API code. The code is more efficient because it doesn't mean another trigger is active in your instance. Smart campaign: You'll want to create a smart campaign with Smart List - Fills Out Form and Flow - Change Data Value, [your field name], New Attribute is {{trigger.Web Page}} You would need to reference the trigger token in the alert email so the team knows what product page the end user filled out the form on. Code: (Embedded Form) This can be done with a hidden field. MktoForms2.loadForm("//app-**01.marketo.com", "***-***-***", 148, function(form) { form.addHiddenFields({ LastFormURL : document.location.href }) }); The asterisks represent your company's Marketo data (your Munchkin ID and Marketo instance). Your developer will know what to do if s/he is already using the embed code. Code: (Marketo LP) In a Marketo LP, you will have to edit the template and put this at the end, before the </body> tag : <script> MktoForms2.whenReady(function (form) { form.addHiddenFields({ LastFormURL : document.location.href }); }); </script>

Issue You are trying to edit an existing email template, and it has the status of "Approved with Draft" However the draft is not showing up in menu tree and when you try to edit and save, you get the error "Not Allowed – Template already has a draft." Solution Issue Resolution Refresh the browser or check is the draft is opened in another window. Try logging out and logging back in Try using a different browser to check it further Check if there is a template with the same name that exists elsewhere (Design Studio) Rename the template and check if that is working If the issue persists, please reach out to Marketo Support for further assistance

Issue When attempting to publish a landing page to Facebook, you get the error "Error when calling Social Campaign API. Warnings: Error while creating facebook tab." Solution If you haven't purchased Ad Targeting add-on for your instance, you could face this issue. You can contact your Customer Success Manager to include this add-on in your Marketo subscription. If you are facing the issue in spite of having ad targeting add on to your subscription, we would suggest that you contact Marketo support and we will be able to troubleshoot it for you.

Issue You want to lock specific parts of an email, such as the From or Reply-To, to prevent certain users from editing them. Solution Through roles and various permissions you can prevent editing of the email as a whole. You do not have the ability to allow only partial edit of an email header such as the From/To. The same applies to Sales Insight emails. Edit permissions are granted for the email as a whole Note: You can prevent people from editing pieces of an email by making those sections non-editable on the template level, but again, this would apply to all users.

Issue You receive an error in ToutApp - "IMAP access is disabled for your domain. Please contact your domain administrator for questions about this feature. (Failure)" Solution This due to an invalid Gmail connection For this error message to be resolved, we recommend looping in with your Gmail Administrator regarding the IMAP access of your domain and whether or not it can be enabled. See the link below for additional reference on this for your Gmail Administrator: https://support.google.com/a/answer/105694?hl=en

Issue Often times variables are used in emails and guided landing pages for marketers to quickly and easily change a link URL in a CTA button. However these links cannot be made dynamic when used with a variable. Solution The variable needs to be removed and replaced with an editable section or a rich text element. Once this is done the editable section or rich text element can be made dynamic. This will require some prior knowledge of HTML as the code of the asset itself will need to be changed. The links below will guide you through the syntax that needs to be used to modify your HTML. Create a Guided Landing Page Template Email Template Syntax

Issue Changing From address on multiple email assets at once instead of one-by-one by hand. Solution You can use program/folder tokens as the from address, and then change the token. Once the token changes it will update the assets using the token. For any pre-existing emails, updates in bulk could be made through a API call to the Marketo API endpoint - http://developers.marketo.com/rest-api/assets/emails/#create_and_update.

Issue Error "API is not enabled for this Organization or Partner" occurs during Marketo - Salesforce integration. Solution This is a Salesforce generated error and indicates that API access is not available in your SFDC instance. For more information, see this Salesforce documentation: http://www.salesforce.com/us/developer/docs/api/Content/sforce_api_calls_concepts_core_data_objects.htm . To resolve this, contact Salesforce to enable API access.
