Every email domain has policies that help decide whether incoming messages should be accepted or rejected. DMARC is one of these policies. It stands for Domain-based Message Authentication, Reporting, and Conformance, and takes effect if an email fails certain types of authentication.

DMARC policies benefit the email community as a whole because they help prevent phishing, spoofing, and the delivery of fraudulent emails. However, strict DMARC policies can sometimes misidentify your legitimate marketing emails as fraudulent and reject them.

DMARC and Free Email Providers


Some free email providers, like Yahoo, Gmail, and AOL Mail, have adopted strict DMARC policies to prevent spam and spoofing. If you use an email marketing tool, such as DX1 Newsletters and you choose a From email address provided by a free email service, that service’s DMARC policy may tell receiving servers to reject your email because it wasn’t sent through them.

For example, let’s say you send a Customer an email response from within the DX1 Lead Manager with a From email address like The email appears to be sent from a domain, but it’s actually sent from DX1’s servers. Yahoo’s strict DMARC policy doesn’t like this. Their DMARC policy tells your Customer’s receiving servers to automatically reject anything that looks like it comes from, but comes from somewhere else instead. 

To improve deliverability, we encourage you to use a From email address at a domain owned by you or your organization, like Not only will this help avoid delivery issues, it can help your subscribers recognize your brand.

Register a Domain

To avoid the consequences of DMARC policy changes of free email providers, use an address at your own domain. Don’t have mail at your domain?
