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.

Summary Some users encounter problems with their Marketo domain not handling URL parameters correctly and resolving URLs. Issue When using URL parameters, some users experience issues where their Marketo domain does not correctly handle and resolve URLs. Cause: The issues can arise due to errors in how the URL parameters are structured, syntax errors, or difficulties in the domain's ability to handle parameters. One common problem is placing the anchor (represented by "#") incorrectly in the URL string, especially before the parameters. Solution URL parameters are extra pieces of information added to a URL to provide specific data or instructions. E.g., Example Domain?parameter1=value1&parameter2=value2 However, incorrect handling of these parameters by the domain may cause issues in resolving the URL, resulting in broken links or incorrect behavior in your Marketo campaigns. Therefore, it is crucial to ensure that URL parameters are correctly managed to avoid any problems. Below are some recommended guidelines to follow while using URL parameters. Proper use of "?" in URL parameters: Start your URL with "?" if it contains parameters. This correctly initiates the parameters and allows the URL to resolve correctly. Example: www.example.com?parameter=value#anchor Verify your domain's ability to resolve parameters: It's possible that certain websites may not be set up to accept or process parameters present in URLs automatically. If you're facing such an issue, it's important to inspect your website's domain settings. This can be done by exploring the configuration options offered by your content management system (CMS) or hosting provider. In case your domain isn't equipped to handle parameters, you may need to reach out to your domain provider for further assistance. Place the anchor correctly: The anchor is typically included at the end of a URL to direct the user to a specific section of a webpage. If you are using parameters in your URL, the anchor must always be placed after the parameters. Example: Incorrect: www.example.com#anchor?parameter=value Correct: www.example.com?parameter=value#anchor Some examples of different URL constructions. Both of these are valid, correctly constructed URLs: www.example.com?parameter1=value1&parameter2=value2 www.example.com?parameter1=value1#anchor In the examples above, the "?" symbol is used to start the parameters, and the "&" symbol is used to separate multiple parameters. The anchor is placed at the end, after the parameters.

Issue Google Adwords gives the error message " This Google AdWords account is already connected to Marketo and can only be used once. Revoke access in your Google account settings and try again." Solution 1. Click on the Gear Menu in Adwords and Click on "Account Access" tab under account settings. 2. Under Actions menu, Select "Edit Google accounts info" for the Adwords user credentials used in Marketo 3. That will bring up a separate page - myaccount.google.com. 4. In the "Sign-in & security" page there's a "Connected apps & sites" section that lists all of the apps connected to the account - one of them should be Marketo. 5. Clicking the "Manage Apps" link should bring up a list of apps, and clicking on the Marketo app should give you the option to Remove. 6. Once removed, you should be able to reauthorize the account in Marketo.

Issue Issue Description When linking Google AdWords account to a Marketo Revenue Model and adding the Google Adwords conversion in the Revenue Model, Set AdWords Conversion button is missing from the Stage Actions drop down. Solution Issue Resolution You need to add Google AdWords as a Launchpoint service with a manager account Add Google AdWords as a Launchpoint Service with a Manager Account - Marketo Docs - Product Documentation

Issue Issue Description An email was sent to leads but immediately returned an 'Email Bounced Soft' Activity Type with the Activity Details stating: 'Details: Empty address: []' Solution Issue Resolution This is due to a token used in the 'From Address' Field in the Email editor that does not have a valid value or valid default value. For example: {{lead.Partner Email:default=edit me}} The Record's field value for 'Partner Email' is Empty. As there is no value for the record the token would use the default value 'edit me' which is not a valid value. A valid value must be an email string format such as mark@eto.com

Issue Communication Failure is displayed when trying to swap an image in a section of the email. Solution This is known to occur when the email contains a significant amount of elements configured with dynamic content. These elements refer to subject, hero-banner, cta-button, etc. For example, for an email that contains 10 elements with 50 segments (used for dynamic content), there are at least 500 versions (i.e. 10 elements multiplied by 50 segments) of the email that need to be updated when an element is updated (e.g. swapping an image) In order to avoid the communication failure or be able to swap an image, try reducing the number of elements configured with dynamic content (i.e. make some elements static where possible.)

Issue Description You sign up for ToutApp and receive a notice that your account is under review or your account is not verified. Issue Resolution If you sign up for ToutApp using a generic email address such as Gmail, Yahoo, Hotmail, Outlook or other email providers your account may require verification by Marketo Support. Please contact Marketo Support with the following information. Company Name: Business Address: URL(s) of your primary Web site(s): What is your average weekly and/or monthly email volume? Do you purchase, or have you ever purchased lists of leads? If yes, which providers have you used and when was your last purchase?

Issue A lead shows as being a member of a campaign that had a single flow step of 'Change Data Value'. However, the lead doesn't show in the Results tab of the campaign, nor is the CDV activity logged in the activity log for the lead. Solution This can happen if the field to be updated was blank/null, and the new value in the CDV flow step is derived from another field, using a token, and this other field is also blank. Because the value 'changes' from blank to blank, we don't log anything in the activity log, but the lead is a member of the campaign.

Summary Marketo Form Does Not Appear on a Landing Page Issue Marketo Form embedded on a Landing Page and the Form does not load. Environment Marketo Solution If you are able to reproduce the behavior in a Private Browsing window using Firefox, then issue is most likely caused by the embed being used. Examine the embed code on the page and ensure that the Form is loading using your instance's Landing Page Domain. For example you may see your embed code formatted as <script src="//app-sj01.marketo.com/js/forms2/js/forms2.min.js"></script> <form id="mktoForm_1"></form> <script>MktoForms2.loadForm("//app-sj01.marketo.com", "123-ABC-456", 1);</script> It instead it should look like <script src="//123-ABC-456.mktoweb.com/js/forms2/js/forms2.min.js"></script> <form id="mktoForm_1"></form> <script>MktoForms2.loadForm("//123-ABC-456.mktoweb.com", "123-ABC-456", 1);</script> Once the embed code has been updated, load the page again and the Form should now appear. Root Cause Firefox released a privacy update that blocks loading of certain elements directly from the marketo.com domain. This prevents Marketo Forms from loading when they point to a source of marketo.com. Updated the embed code to use your Landing Page Domain allows the form to load correctly.

Issue Why is the number of records shown in the Opportunity Analysis report in Revenue Explorer different from the number of records shown in a Smart List with the same filters? (e.g. 100 records in Opportunity Analysis vs. 200 records in smart list) Why are some records in the Smart List that do not appear in the Opportunity Analysis report? Solution The attribution settings are set up to report on "Explicit: Only contacts with roles (default)" This means, the records in a Smart List that do not appear in the Opportunity Analysis Report in RCA are contacts without roles.

Issue Description You receive an error in ToutApp - "IMAP access is disabled for your domain. Please contact your domain administrator for questions about this feature. (Failure)" Issue Resolution 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: support.google.com/a/answer/105694?hl=en

Issue You are setting times using natural language inputs, but are wondering: if I set a constraint of "in past 2 days", will that looks at the last 48 hours or will it look at the last two calendar days from Midnight-Midnight based on the timezone specified in my instance? Solution Using a constraint that is looking "in past 2 days" will look at the last 48 hours, if it was set as "in past 3 days" it would look at the last 72 hours, etc.

Issue Description When we delete the static lists from a program after a period of time, will the leads they contain no longer be member of the program? Issue Resolution The individuals should still be a member unless you change their membership status to remove them. Remember lists are simply collections of individuals so you can easily process or associate them, they don't automatically get "membership" unless you had corresponding flow steps that you used when putting them on the list.
