How do I set up the Yahoo feedback loop?

A feedback loop (FBL) is a communication channel with an Internet Service Provider (ISP) that allows spam complaints to be sent back to WordFly. Spam complaints (also known as 'abuse complaints') are sent when a subscriber clicks on the 'this is spam' button in their email. All abuse complaints sent back to WordFly are removed from your future imported lists to follow ISP posted best practices for handling these responses. 

Most ISP FBL's are IP based which means that WordFly has already signed up for those FBL's because we manage your sending IP.

Yahoo is the only ISP that has a domain based FBL. Yahoo requires a few things before signing up for their feedback loop program: DKIM published on the sending domain, a postmaster@ mailbox, and a Yahoo email account. Once these requirements are met your team can finish signing up for the Yahoo FBL following the instructions in this article.



Signing up for the Yahoo FBL

Before starting this process, make sure you have completed these items:

  • DKIM published for your sending domain
  • Postmaster@ mailbox set up and ready to receive incoming emails
  • Yahoo email account (either a personal account or company use account works). If you do not have a Yahoo email account, go to and select Create Account, follow Yahoo's instructions to create an account.


Are you using Gmail for your company emails? Gmail removes access to the postmaster@ mailbox which makes it difficult to set up the Yahoo FBL. Open a support ticket with Google, explain you need to set up the Yahoo FBL using the instructions in this support post and they can help you with the verification code sent to the postmaster@ mailbox.

*Let WordFly support know if you need assistance with any part of this process by replying back to your WordFly onboarding ticket or other open support ticket.

If you are not receiving the Yahoo FBL email you might try (1) confirming that your postmaster mailbox is actually receiving any outside emails at all, if you can't find this message you probably have a problem to fix before finishing the FBL, or (2)
check to see if your mail server is rejecting the verification code email message because the from line used by Yahoo is too long (this is mostly an issue on the PowerMTA platform).

-Open the email from Yahoo and retrieve the verification code.
