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 Description The exact distinction between the "Email Bounces" and "Email Bounces Soft" filter and trigger is unclear. Issue Resolution The “Email Bounces” trigger or filter will look only at hard bounces, where Marketo received a definitive "No" from the target server. The “Email Bounces Soft” trigger or filter only looks at soft bounces, which occur when we are unable to deliver the email, but did not receive a rejection from the target server. You can use both filters with "OR" logic in order to look at all bounces.

Issue Issue Description How to add a seed list in a batch Smart Campaign or Email Program. Solution Issue Resolution Import the seed list addresses into an appropriately-named static list Add a filter in the Program/Campaign Smart List to include the static list. The trick will be to make sure the filter logic is correct. Advanced Logic may need to be used in the Smart List of the Program/Campaign. For example, if there's a sending campaign with 5 filters to send to an audience 1 AND 2 AND 3 AND (4 OR 5) then you will want to use Advanced Logic and put parentheses around the original filter set (1 AND 2 AND 3 AND (4 OR 5)) and add the seed list outside the parentheses with OR logic (1 AND 2 AND 3 AND (4 OR 5)) OR 6 In that advanced logic, the original intended membership (1 through 5) exist within its own set of parentheses and the Seed List is included in addition (OR 6).

Issue You see a record in the database has something similar to the following Email Suspended Cause: "554- Your access to this mail system has been rejected due to the sending MTA's poor reputation. If you believe that this failure is in error, please contact the intended recipient via alternate means." Solution The 554 error is generated by a hard bounce due to a spam block. It is possible that one of the sending IP addresses used may have been on a temporary blacklist the day of the attempted send. This happens while using shared IPs when another Marketo instance using the same IP hits a spam trap, putting the IP on a blacklist for 24 hours. This error can also happen to users on a dedicated IP if they hit a spam trap with one of their email sends.

There are thousands of blacklists out there and all of them operate a little differently and all have varying levels of reputation. There are only a dozen blacklists that really can impact delivery. The blacklist that requires the most work from you when you request delisting is Spamhaus. Spamhaus is a trustworthy blacklist and if you are listed at Spamhaus you have made a mistake that will need to be directly addressed before the listing can be removed. SpamCop is considered a tier one blacklist for B2B marketers but a tier 2 for B2B marketers. Marketo responds to all SpamCop listings; researching to identify the source so we can work with the customer to educate on best practices and prevent future listings. Some blacklists require that you pay a fee to be delisted. These blacklists are not favored in the email community because they use this tactic. For the most part, Marketo advises our customers not to mind alerts of being listed on a pay-to-delist blacklist. These blacklists tend to have minimal impact to your deliverability. For the most part blacklists are dynamic and resolve themselves in around 24 hours if the issue resolves. If the problematic sending continues, of course, the blacklist will continue to keep you listed until the problematic sending ends. If you are blacklisted, your main concern at that point should be making sure it doesn't happen again. For steps on how to identify the problematic data source and improve your list hygiene in an effort to avoid blacklist issues, see our blacklist remediation article.

Unemotionally Subscribed – People on your list who have not opened or clicked an email message from you in an extended (several months) period of time. They have not unsubscribed. They have not marked your message as spam. They either ignore it or take the time to actually delete it every time it lands in their inbox. Now, it depends on who you ask, but the percentage of your list that is considered “unemotionally subscribed” can be as high as 30%. Yup. Nearly one out of every three folks on your email list are not interacting with your emails … not at all. As I mentioned in this What Counts guest post, once you figure out who fits this “inactive” criteria, you have a few options: Immediately unsubscribe or delete them. I call this the “DO NOT PASS GO, DO NOT COLLECT $200″ approach. Move to a new list and mail to less frequently. I call this the “I think I need to see you a bit less often” approach. Send a last ditch “We missed you” type email. If they don’t respond, then do #1. I call this the “I’m going to give you one more chance” approach. Set up a re-engagement email series. I call this the “I really don’t want to break up, but if you are not responding at all, well, it’s over” approach. No one method is necessarily better than the other. I’ve seen all 4 executed before. As I often say, the best practice here is the one that’s best for your subscribers (and your business). I recently came across a great – creative, human, funny – example of #3, the last ditch “we missed you” email. Thanks to Suzanne Oehler who forwarded me this email. Check out this email from NTEN: The Nonprofit Technology Network The subject line – We miss you! - was certainly one that would stand out in many inboxes. The intro paragraph was short and to the point, but nothing crazy. But then it got fun … and creative. The first call to action read: “If you’d like to continue receiving NTEN emails, click here by Friday, August 2nd. Yay! This makes us very happy.” Again, they get right to the point. They even add a bit of “human” (Yay! This makes us very happy.) But it gets better. The “click here” link leads to hilarious Happy Dog video. IF you are a dog owner, you’ll love this. The second call to action read: “If you’d rather not receive NTEN emails, we’re sad to see you go. Simply delete this email and in a short time your account with NTEN will be removed from our systems.” Nothing crazy. Direct. Clear. Simple. However, the “sad” link again goes to a video – this one goes to a Sad Cat Diary video. Warning: some language in this video is NSFW. Then again, if you’ve ever owned a cat, you’ll appreciate the humor. The third, and final, call to action read: “Of course, if you change your mind, you can always sign up again” with the “sign up” link taking clickers to their email subscription landing page, of course. Now, fun and creative is one thing. If campaigns like these do not meet their intended goals (getting folks re-engaged), then, well, they are just “fun and creative.” So … Did It WORK? I contacted the team at NTEN to see how effective this campaign was. Below is what they shared with me. They sent this email to a list of 24,000 subscribers who had not opened in email from them in the past year. For this particular campaign, they reported the following metrics: Open rate – 38.89% vs. 26.73% “average” over the previous few emails Click-to-Open Rate* – 47.37% vs. 12.3% “average” over the previous few emails *in other words, of the 38.89% who opened the email, nearly 50% clicked at least one link Of those who clicked a link, the Top 4 most-clicked links were: 41.14%: Click Here (Happy Dog … to stay subscribed) 4.91%: Unsubscribe 2.21%: Sign up 2.14%: Sad (Sad Cat … to opt-out) By all accounts, I’d say this “We Miss You” campaign was a HUGE success? What do you think? Have you tried a “reenagement campaign in the past? If so, how effective was it for you? Drop a note in the comments below! P.S. The email marketing team at NTEN shared their “lessons learned” from this campaign in this blog post. I love their transparency. Is this article helpful ? YesNo

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.

As part of your efforts to maintain a healthy inbox delivery rate, you should be monitoring your email bounce rates. If your hard bounce rate climbs above 5%, you should take a closer look at what’s going on. If your hard bounce rate hits 10% or more, you should be concerned about your data quality. If you have a high hard bounce rate, it is likely that you have a high number of invalid addresses. An invalid address is an address that has never existed or no longer exists, so mail will never be delivered to these addresses. Marketo automatically stops sending to these addresses, so you do not need to worry about suspending or removing them. But having a high invalid address rate could cause you major delivery problems and reputation issues, and could indicate problematic data sources or list segmentation practices that should be reevaluated. A high invalid address rate can lead to outright blocking of your mail at major ISPs. Many ISPs monitor the number of invalid addresses being sent to at their domains by specific senders. Once a certain threshold is hit, those ISPs will block mail coming from the offending sender. ISPs behave this way because they view a high rate of invalid addresses as an indication of problematic data practices of the sender. At best, a high invalid address rate means you are not sending to an engaged, active audience. At worst, it means that you are sending to purchased or rented lists, which is a violation of Marketo’s Email Use and Anti-Spam Policy. Chances are, if you have a high invalid address rate, there are other issues with your data that could also contribute to. If you receive a notification that we have noticed a high invalid address rate associated with your mailings, you should ask yourself some questions about your list management practices. Below are some things to consider: - Have you recently added any new leads or lead sources? Purchased lists are often full of invalid addresses. We often find that purchased lists contain numerous addresses from domains that don’t even exist any more. While you can use purchased lists to bulk up the data you have for existing leads, you cannot use them to bulk up your lead database. -Have you recently targeted old or inactive leads? We strongly recommend that you never send to an address that you haven’t mailed to for over a one year. You should be mailing to your contacts at least every six months. This will help prevent high invalid address rates, and will also help keep you and your content fresh in your contacts’ minds. If you do have to send to older leads, you should break up your lists and send to your most recent and active contacts first. - Who are you targeting? Some senders have more problems with high invalid address rates because of their target audiences. For example, targeting .edu domains often causes high invalid address rates because these are school addresses that have a higher turnover rate. B2B campaigns may sometimes have higher invalid address rates because of similar turnover rates at businesses. The best way to avoid high invalid address rates is to send to opted-in, engaged recipients. To help with this, a lot of senders clear out their inactive leads every six months or so. An inactive lead is a contact that has taken no action in the given time period— they haven't opened an email, clicked a link, visited your webpage, attended a webinar, and so forth. This can help with both your high invalid address rates and spam complaints. Inactive leads are a dangerous group to continue mailing to because their behavior proves that they do not want to interact with your mail, and will therefore likely complain to us or to their ISPs about it. We have a great resource on how to create a Smart List to remove inactive leads here. If you still need some help, please feel free to reach out to our Support team (support@marketo.com).

From the Marketo Email Use Policy: "...You may not send any Unsolicited Email by use or means of the Marketo Service. "Unsolicited Email" is defined as email sent to persons other than: persons with whom you have an existing business relationship, OR (ii) persons who have consented to the receipt of such email, including publishing or providing their email address in a manner from which consent to receive email of the type transmitted may be reasonably implied." The full text of the policy is here: https://documents.marketo.com/legal/use-policy/ An abuse report is a report that an individual sends to abuse@marketo.com alleging that a Marketo customer sent unsolicited email. There are a number of reasons why someone might report abuse. Here are a few common reasons people report abuse to us: The person forgot they opted-in to the mailing The person received genuinely unsolicited email The person opted in, but the branding in the email was different than the branding on the opt in form so it was not clear the email they received was connected to their opt-in experience Someone signed up for your list with the wrong address, and the person who actually received your email felt it was abusive For additional reference - Abuse Report Deep Dive

Before sending a Marketo email, you can preview it in order to ensure accuracy and the correct design. In Design Studio, find the email in the tree. Clicking on the email opens the Details page for that email. Click Preview Email to see the email as recipients will see it. You can also preview an email from the Email Actions dropdown menu. The Previewer provides a highly accurate rendition of your email. You can even preview every possible combination of content that can be generated using Dynamic Content and lead data brought in by tokens. For emails using Dynamic Content, you can send multiple versions of a test email at one time, up to 100 emails all sent to one specific email destination. If you are using the View Lead Details option, you can use a list you select. The list can be created expressly for this purpose. If the list is longer than 100 leads in length, only the first 100 leads will be used. Marketo creates variations using the content you specify for the Segments that leads belong to; tokens are also resolved. This allows you to see exactly what your users will see when they receive the email, even when you use multiple Segmentations in a single email. Note: If the email, and the campaign that sends it, are in the same Program, each My Token will resolve to the value appropriate to that Program. However, if the email and the campaign are in different Programs, the My Token resolves differently depending on how the email is sent. For sending test emails and single flow actions, the My Token resolves to the value appropriate to theemail’s Program; for emails sent by campaigns, the My Token resolves to the value appropriate to the campaign’s Program. Is this article helpful ? YesNo Use the Previewer To preview an email, find it, then follow these steps: 1. In Marketo Lead Management, choose the Design Studio tab. Look at the tree on the left-hand side of your screen. 2. In the tree, click the + next to Emails. A list of landing pages opens. 3. In the tree, click the email you want to use. Details appear for the email. 4. Click the button, Preview Email. The Previewer opens. 5. Inspect the page carefully. 6. If you find problems, click Preview Actions, and choose Launch Editor. You can then fix problems in the Email Designer. 7. If you used Dynamic Content, the version shown is the Default for all Segmentations used by the email. To view other versions, choose View by Segment from the pull-down; use the left and right arrows, and the Segment pull-down in the top right corner, to view each combination of Segments. The version of the email reflecting each combination of Segments displays. 8. If you used Tokens or Dynamic Content, and you want to see how the email will render for a set of preselected leads, choose View by Lead Detail from the pull-down, then choose a list from the pull-down in the dialog box which appears; use the left and right arrows, and the pull-down, to step through the leads. The email updates with information for that lead. 9. To send a test email, for any version of the email, bring that email onscreen in the Previewer; then, click Send Test. That version of the email will be sent as a test email. Tokens at the global level will be resolved; My Tokens – tokens that are a local asset to a Program – will not. 10. When finished, close the Previewer.

Issue You want to set up a DKIM key on one of your domains or subdomains, but another service has a DKIM key already set up on the selector/domain combo. Solution Beginning October 2023, Marketo has upgraded it's DKIM feature to allow for a Custom Selector for DKIM Keys. Most Users will be able to utilize the prior default selector, m1, as their DKIM Key. However, if another integration is already utilizing the m1 selector, a custom value can be used. Common ones seen are "m2", "a1", "mkto", etc. It can be longer, but shorter is generally better Afterwards, you'll be able to validate DKIM as detailed in documentation: https://docs.marketo.com/display/public/DOCS/Set+up+a+Custom+DKIM+Signature

Leads can be auto unsubscribed due to default Feedback Loop setup with the ISPs listed on this page. You can use the following filters to find leads that have clicked the SPAM button in your emails: Filter 1: Data Value Changed Attribute: Unsubscribe New Value: True Reason: Contains, Customer Complaint Received from ISP. (Optional to Specify what Email Domain) Filter 2: Email Address Email Address: Contains, @domain.

If you sent an email from the Lead Database (as a Single Flow Action), as part of a campaign, or as a test email but didn't receive it, here are some tips. Check the "From:" address When sending a test message, make sure to check the "From:" address setting on your message. To do this, go to the Email Settings tab of the email editor. In the "From:" field, make sure that you either have a single valid email address, or a valid email address as the default. Many people want to send their messages from the lead owner. When you use the send test feature, the email address you are sending to doesn't have a full lead record, and so it doesn't have a lead owner. Since Marketo cannot send an email with no "From:" address, test messages without a valid email address in the "From:" field will not send. Send as a Lead If you have verified that the email had a valid From: address and you still aren't getting it, make sure to create yourself as a lead and send using a flow action. See if the mail was sent If you sent the email as part of a campaign or Single Flow Action, check the campaign's Results tab or your lead detail page to see if that mail was already sent to you. If it hasn't been sent yet, try waiting a little while longer. Check your Junk Mail In your email client, check your Junk Mail or Spam folder to see if the mail landed there. If it did, you should change the content of your email. Check your corporate spam filter Your corporate mail server may have blocked emails from Marketo; you should contact your IT department to see if this is the case. Please see our instructions for whitelisting Marketo's email servers: Add Marketo to Your Corporate Email Whitelist Try sending to a different recipient If you sent the original mail to your corporate account, try sending to a personal account on Yahoo or Gmail. If you sent it to a personal account, try your corporate mail account. Use Marketo's Email Deliverability product The Email Deliverability PowerPack, with Design Informant and Inbox Informant, can warn you when your mail is being rejected because of its content and help you identify junk mail pitfalls. Also, using Domain Keys and SPF improve the chances of your email landing in your leads' inboxes. Contact Marketo If you still can't figure out what happened contact Marketo to see if we can help.

Quick points: *Spamtraps are addresses owned by antispam organizations *Emailing a spamtrap (usually) gets your IP or domain blocklisted *Maintain current, direct opt-in with an active lead database to avoid this What is a spam trap or spamtrap? A spam trap, or spamtrap is an email address secretly owned by an antispam organization that is used to detect spam. Antispam organizations do not sign up for mailing lists, so they consider any email sent to these addresses to be spam. Once email is sent to the spamtrap, the antispam organization that owns this address will blocklist the IP that sent the email (or, less often, domains that are linked in the message). Email administrators purchase subscriptions to various blacklists, and use the lists to block all incoming email from listed IPs or containing listed domains. From the marketer’s perspective, this can mean a high number of bounced emails leading to low lead engagement, and ultimately to weak revenue performance. There are two types of spamtraps – pristine traps, and repurposed/recycled traps. A pristine trap is an email address that was never used by a person. A repurposed trap is an email address that once belonged to someone but is no longer a valid address; these addresses will bounce as bad addresses for at least six months before an antispam organization will turn them into live traps. How can a spamtrap get into my Marketo lead database? Purchased data Purchased data is unreliable. The antispam world does not like the use of purchased data so antispam administrators have made a concerted effort to get spamtrap addresses into the databases of data vendors. While data vendors may say they provide opt-in data in reality consent should be direct to your company. Sending unsolicited email is prohibited by the Marketo Terms of Use because this practice has a high risk of causing blocklist issues that can destroy deliverability for multiple Marketo customers. To avoid spam traps get direct opt-in before sending email. If you have purchased data in the past we recommend setting any inactive purchased leads to marketing suspended or simply removing them from your database. Old data Repurposed traps are email addresses that were once valid but are now owned by an antispam organization. This can happen when a company goes out of business; expired domains are often purchased by antispam organizations. Sometimes a company that has a direct partnership with an antispam organization will allow email addresses of former employees or users to become spamtraps. Because antispam organizations will generally make sure future spam traps return a bounce as bad addresses for at least six months before they become spam traps you can prevent repurposed traps in your database by emailing remaining engaged with everyone in your database at least once every six months. Avoid “wake the dead” campaigns to addresses you have not contacted in more than six months. Unconfirmed form entries People can unintentionally enter spamtrap addresses into forms either by making a typo or by intentionally using a fake email address that happens to be a spamtrap. If you use single opt-in, you may add spamtraps to your mailing list. This is more likely to happen if you are a B2C company or if someone thinks they can get whitepapers or free trials simply by filling out a form with made-up information. How can I identify spamtrap addresses? Spamtrap addresses are considered trade secrets by the antispam organizations. They do not share these addresses because their goal is for senders to change their mailing practices rather than to simply remove spamtraps from their mailing lists. That said, one thing we do know about spamtraps is that they tend to be automated processes and do not engage. Spamtraps do not click links. You can use smart list filters to identify inactive leads in Marketo. How can I prevent spamtraps in my database? Maintain active, direct opt-in for all leads. Don’t purchase data (to grow your list, sponsor events, use list rental services that send the first message for you, or use co-branded content that sends you only good leads) Email everyone you want to email at least once every six months Don’t add old data directly to your mailing list (if you need to, add in small batches and send a welcome email with a slightly different subject to each batch) Regularly clean your database of inactive leads Grant access to assets such as free trials and whitepapers as email links to discourage intentional use of fake email addresses on forms Use scripting on your forms to identify potential typos Is this article helpful ?

We manage our network to provide our customers with the highest server availability and best deliverability possible. Marketo Engage has a strong anti-spam policy and a team that handles blocklist notifications in our IP space and spam complaints. We also cooperate with most major anti-spam providers and ISPs. In addition, we maintain feedback loops for many of the most popular email providers. For more information on feedback loops and ISPs with whom we have this arrangement, click here. Blocklistings are usually caused by sending mail to a spam trap email address. For an explanation on what causes blocklisting, click here. When we receive notification of a blocklisting, we react in two ways. First, we go through the procedures to remove the listing from that blocklist as soon as possible. Second, we determine (if possible) which of our customers caused the blocklisting and work with them to improve their mailing lists to prevent a reoccurrence in the future. This is usually a cooperative process, most frequently, a review of mailing policies and strategic pruning of a customer’s lead database will return them to best practices.
