Email Suppression List
FellowshipOne uses a Suppression List on our email servers to improve our reputation among email providers and, in turn, the reliability of delivering our church's emails. If a recipient is not receiving emails, our Support Team can check this list and remove addresses from it. Feel free to call our Support Team at 866.383.2437, option 1 or send us an email at

Why use a Suppression List?

Many major mailbox providers (Google, Microsoft, Verizon Media, etc) calculate and maintain reputations for IP addresses and domains. Some of the factors that go into this reputation are invalid address delivery attempts and complaints from end-recipients. To protect your account from attempting delivery to bad addresses or any users that have previously complained we maintain a Suppression List for your account. This will prevent delivery attempts to any address on this list. It will help ensure you maintain a quality reputation and help increase inbox delivery rates.*

What makes an address appear on the Suppression List?

There are two ways an address can appear on the Suppression List:

  1. The receiving mail server responded with a permanent error response, such as: "550 5.1.1 User unknown In response to the RCPT TO command." This is most commonly encountered when attempting to deliver to an address that does not exist.
  2. The person receiving the message hits the spam/junk button in a browser/client that supports feedback loops. These will appear in your list as "Complaint".*

How do I remove an address from the Suppression List?

If the address was added to the Suppression List because of a permanent error response (option 1 above), then our Support Team can remove the address from list directly. If the address was added because it was marked as spam/junk, then our Support Team can send an email to the address with a link allowing them to opt back in to receiving emails through FellowshipOne. Following the link will remove the address from the Suppression List and allow them to receive emails.
