@Yahoo.com FROM EMAIL’s No Longer Deliverable

As of April 9, 2014, Yahoo made a change to their DMARC (Domain-based Message Authentication, Reporting and Conformance) records, which could affect your email marketing deliverability.

The cliff-notes version: Yahoo will no longer allow an email sent from a @yahoo.com email address into their servers if the email was not sent from within yahoo (for full techy-details click here).

What does that mean for your Campaigns?

Customers using an email service provider (like Mail Dog) should no longer use a @yahoo.com email address as the FROM EMAIL when sending a campaign.

Yahoo will recognize the message as not truly originating from within the Yahoo.com servers and block any email from being delivered to other @yahoo.com email addresses.

If you typically send campaigns using a @yahoo.com FROM EMAIL address, please change to a different from email address. You can either set-up a new email address within your website domain (ie: info @ company.com) or you can open another free email address at any other online email service like Gmail or Hotmail.

Yahoo.com is not commenting on whether this is a permanent change or if they will allow for advanced whitelisting overriding this rule. For now, the only option for best deliverability to @yahoo.com emails is to conform to their new standard.
