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 companies use a technology called DMARC to safeguard their domain names. DMARC policies tell other email servers on the internet who is allowed to send email with a particular "From Email" address. Let's take Yahoo for example. Yahoo requires that any email that has a "From Email" address ending in "@yahoo.com" must have been sent from a trusted Yahoo email server. When an email server receives an email that purports to be from "yahoo.com", it can check to see if the server that sent the email is on Yahoo's approved list. If it is not on the list, then the email may be bounced, blocked, discarded, or sent to spam.
These policies are aimed at preventing fraudulent email, but they can also impact mailing lists and email service providers that send "on behalf" of other domain names. If you are using a "From Email" address that is protected by a DMARC policy, your email campaigns may experience some deliverability issues.
If you are using a free email service (like AOL, Gmail, iCloud, or Yahoo), the solution is to simply use a different "From Email" address for your email campaigns. The best solution is to use an email address from a private company domain that you control—like email@example.com.
If you are already using a private company domain and are still seeing these warnings, don't worry! You (or your IT person) can add Direct Mail’s email servers to your company's list of trusted email servers. Just take a look at this help article for information on how to set it up.
