What is a Suppressed Marketing List?
Suppressed Marketing Lists help you avoid sending emails to opted-in recipients to whom the email may not be relevant or necessary, such as the previously mentioned event registration scenario. They are not meant to act as a replacement or backup for the standard unsubscribe process. Regardless of whether you decide to use a Suppressed Marketing List, Click will still exclude any members of your marketing list who have previously unsubscribed from your emails. Suppressed Marketing Lists will also exclude recipients from Transactional emails as well.
You may select one or more static or dynamic Marketing Lists to exclude from your Email Send. For example, if you want to email people who have not yet RSVP'd for an event you are hosting, you can use your original Marketing List of possible attendees as the one you will send to, and set other Marketing Lists of people who have already said they will attend and people who have already said they will not attend as your Suppressed Marketing Lists for the Email Send. Anyone on the Suppressed Marketing Lists() will be excluded from being sent the email, even if they are on the original Marketing List of possible attendees that was set for the Email Send if the email addresses match.
How can I add a Suppressed Marketing List to an Email Send
You can add Suppressed Marketing Lists via the grid within the Email Send record draft. Click the plus sign and choose the desired Marketing List(s). In this example, we have included the various Marketing Lists of Contact who have already RSVP'd to the event.
To add a Suppressed Marketing List to your Email Send, you can also click on the Related menu arrow in the Tab Menu, and choose Suppressed Marketing Lists.
Click Add Existing Marketing List and query for the list(s) you would like to use for suppression purposes.
In this example, we have included the various Marketing Lists of Contact who have been added to lists specifically for suppression.
When the Email Send is sent out, Click will refrain from sending the email to anyone who may exist on both the specified Suppressed Marketing Lists and the original marketing list of recipients. You can see these excluded recipients under the Email Send's related Excluded Emails. More on excluded emails here.
Cautionary Notes
NOTE: While Suppressed Marketing Lists are very helpful, it is still important to keep your Marketing Lists clean. For example, if you send an Email Send to 10,000 recipients while including a Suppressed Marketing List for 9,500 of those recipients, you are putting a lot of unnecessary strain on your environment. Depending on your environment's performance capabilities, this may result in your environment generating a timeout error during the Email Send processing, thus pushing your Email Send into Error Recovery.
NOTE: If you are using automated processes to trigger Email Sends containing Suppressed Marketing Lists, ensure that you are never executing multiple Email Sends with the same Suppressed Marketing List at the exact same time. This can cause an error with accessing the Suppressed Marketing List and one or more of the Email Sends may fail. If this does occur for you, simply re-send the failed Email Sends individually.
FAQs
Can I use one Suppressed Marketing List for all my contacts/leads?
No. Suppressed Marketing Lists are based on entity type—remember that they are a Marketing List which you have to set to the Contact, Lead, or Account entity. So when sending an email only to Leads, a Lead-targeted Suppressed Marketing List can be used.
However, if contacts are also on your Email Send, even if a contact has the same email address as a lead that should be suppressed, the contact will be sent to. The Lead-targeted Suppressed Marketing List can't suppress a contact since it's a different entity. Ideally, you won't have duplicate email addresses in your Dynamics anyway, but if you do need to account for all entities on an Email Send, just be sure to add a Suppressed Marketing List for each entity you're sending to.
