When attempting to send an email campaign, Direct Mail may present you with a warning similar to the following:
"The email policy for yahoo.com requires that senders use only authorized mail servers. Using this 'From' address may cause your email to be blocked or bounced by some servers. Please considering using a different 'From' address…"
What's this all about?
Some domains (like Yahoo.com and AOL.com) use a technology called DMARC to digitally publish policies governing how their domain name can be used. Let's take Yahoo.com for example. Yahoo requires that email bearing a yahoo.com From address must originate from a Yahoo mail server IP address. Email providers like Gmail, Hotmail, and others who use DMARC will reject yahoo.com email that is not sent from Yahoo mail servers. These policies are aimed at preventing fraudulent email, but they also impact mailing lists and email service providers (like us). Mailing lists and email service providers like Direct Mail send email using their own mail servers, not Yahoo mail servers, which could cause legitimate email campaigns from yahoo.com addresses to be bounced or marked as spam.
However, there is a solution.
If you are using a free email service (like Yahoo or AOL), the solution is to simply use a different From address for your email campaigns. The best solution is to use an email address from a private company domain—like firstname.lastname@example.org. If that is not an option, you can use an email address from another free provider that does not publish DMARC policies. But again, the best solution is to use a private domain (it looks more professional, anyway).
If you are already using a private company domain and are still seeing these warnings, don't worry, that's good! That just means that your company is doing its part to prevent fraudulent email and spam from your domain. You can authorize Direct Mail to send email from your domain. Just take a look at this help article for information on how to set it up.
