DMARC changes that affect email addresses

On April 14, 2014, Yahoo! made some email authentication changes to stop spam. On November 2, 2015, and have also made these changes.

On April 22, 2014, AOL made the same changes that Yahoo! had made, and on June 17, 2015, ZenDesk also made the same change.

Google is expected to makes similar changes for on or before June 1, 2016.

Specifically Gmail, Yahoo!, AOL, Zendesk,, and have updated their DMARC record. DMARC (Domain-based Message Authentication, Reporting & Conformance) is used by many major organizations and ISPs to help them identify issues with email authentication abuse. While using DMARC is great for reducing email abuse issues, changes like the one that Gmail, Yahoo!, AOL, Zendesk,, and have made will have a widespread impact on its users.

Why you should use email addresses from your own domain as your From Address

As of this writing, Gmail, Yahoo!, AOL, Zendesk,, and have changed their DMARC authentication standards to a DMARC = reject policy. Based on this information, Gmail, Yahoo!, AOL, Zendesk,, and email addresses cannot be used as your list's "From" address. Once these new standards are adopted, any email campaigns sent with those email addresses in the "From" line will require that AWeber send your campaigns from an alternate email address.

This is not an AWeber-specific issue, these changes impact anyone using an email service provider with a sender address from Gmail, Yahoo!, AOL, Zendesk,, and So if you use ANY third-party mailing service (such as AWeber or any of our competitors) to send emails for you on behalf they will also need to change the "From" address you send with or your emails will not be delivered.

How AWeber will fix your From Address

If you have a "From" address configured in your account that is one of the many providers now setting a DMARC = reject policy, AWeber will automatically rewrite your outgoing emails to be compliant.

For example, if you were using:

It will be rewritten as:

Note: Your Reply-To address will still be shown as

This rewriting process is automatic, you don’t need to take any action for it to happen and it is generally transparent to your subscribers. If you desire to not have your address rewritten, simply change your "From" address to use an email in your own domain name or another email inbox provider which does not have a DMARC = reject policy.

You are able to use the free domain address without any issues moving forward. Your subscribers will see as the From Address in their inbox.

If you are receiving subscribers from Gmail, Yahoo!, AOL, Zendesk,, or

These changes do not affect subscribers from being added to your mailing list that are using Gmail, Yahoo!, AOL, Zendesk,, or email addresses. They will be able to sign up to your list as usual without any issues.

Why have these DMARC changes been made?

While these changes are reasonably new, it was only a matter of time before they were made. Free email providers have always worked hard to reduce the amount of spam that looks like it is being sent from their networks. They made the DMARC = reject policy change to prevent malicious users from sending spam using their domain and that change also impacted legitimate users like yourself.
