Email Feedback Loop
Email Feedback Loop (FBL) is a mechanism that allows email senders or email service providers to receive feedback from mailbox providers regarding recipients who have marked their emails as spam. It enables the sender to remove those recipients from future mailings. You can read more about this process in this blog post: Understanding Email Spam Complaints and Feedback Loops
How is FBL implemented in the Platform?
You do not need to register for FBL programs of various mailbox providers. The SAP Emarsys Customer Engagement Platform is subscribed on the organizational level, and FBL report processing is integrated into each individual account.
When a mailbox provider sends an FBL report, the recipient's email address is automatically added to the special suppression list of your account. This suppression list ensures that the email address of the person who complained is excluded from all future launches.
Linked sub-accounts, or parent/child accounts share the same complaint suppression list.
You can send triggered or transactional notifications to suppressed contacts, including other types of blocklists (Internal, global suppression, Robinson Lists), with the Transactional Opt-In feature which can be enabled by our support team by request.

Re-enabling a contact after spam complaint
If a subscriber requests to be re-added to your mailing list after being suppressed due to a spam complaint about one of your past emails, follow the process outlined below.
Note that you should retain the proof of this re-enabling request from your subscriber. It allows your company to verify that the recipient has agreed to receive emails and ensures legal compliance. It also serves as evidence in case of legal complaints or inquiries from mailbox providers concerning ongoing mailflow after an FBL report.
- Create a support request ticket to initiate the re-enabling process. In this ticket let our team know the email address that should be re-enabled. Also, confirm that you have a proactive request from the owner of the email address and that you will retain this proof of consent.
- After reviewing the information, the Emarsys support team removes the subscriber's email address from your accounts complaint-suppression list. The subscriber will be included in future email launches.
- As the subscriber has previously marked emails as spam, the mailbox provider may initially place the emails in the Spam folder. Encourage the recipient to actively mark the emails as "Not spam" for proper inbox delivery.
