Will Yahoo’s changes affect your deliverability?

Yahoo recently changed its authentication policy, and the change could impact delivery of emails that come from yahoo.com addresses. That means if you send a campaign and your From address is a personal address at yahoo.com, there’s an increased chance your emails will go to spam or bounce.

These recent changes to their DMARC (email routing/authentication) policy means that any mail sent from a @yahoo.com address but not routed through Yahoo’s SMTP servers will be rejected by receivers who respect DMARC policies including Gmail, Hotmail, and many others.

With this change, using a yahoo.com From address when sending through an email service provider like NewZapp will make the email look fraudulent, even if it’s not. So if you continue to try to send your emails from a @yahoo.com address your emails will most likely be rejected (bounced).

This change is affecting all ESPs, not just NewZapp. Although we authenticate your messages as being part of our mail network, we cannot authenticate them as part of Yahoo’s mail network.

So if you’re currently using a @yahoo.com email address as your From address we recommend changing this to an email address at a private domain you control, like @joebloggscompany.com.
