High volume of soft bounces from Yahoo, AOL, and Verizon email addresses in Account Engagement

Date de publication: Jun 18, 2025
Description

Occasionally, you may see a higher than usual amount of soft bounces in an email, stemming from prospects with an @aol.com, @yahoo.com, and/or @verizon.com email address. The bounce error message would look something like this:

Soft bounce - Other [4.3.2 (system not accepting network messages) [TSS04] Messages from {{your Account Engagement sending IP}} temporarily deferred due to user complaints - 4.16.55.1; see {{a webpage containing more info}}]

This is the result of volume-based filters on the recipient’s end. The recipient mailservers are receiving too many emails coming from your sending IP in a given period of time, and are choosing to not accept them.

Résolution

There are 2 options to help circumvent these filters:

1) Create a separate list for prospects with AOL, Verizon, or Yahoo email addresses, and send to them in smaller batches. We are unable to specify how small the batches should be, as the operation of these filters varies. We recommend starting with a couple hundred and slowly increasing over time. 

2) Fill out a Yahoo Feedback Loop form.
This article will cover all the steps and details necessary to register your email sending domain with Yahoo's database, which will help prevent these situations. We highly recommend this for all Account Engagement accounts.
