Yahoo! Mail bounces itself, or why using a webmail address is a bad idea

By Ros Hodgekiss on 8th April 2014

Recent changes within Yahoo! Mail mean that it's bouncing email sent from @yahoo.com addresses, but not actually originating from Yahoo's servers. Apart from outlining this issue, we thought it was a good time to revisit a bit of email marketing best practice - and why it isn't wise to use a webmail address in your sender details.

The story begins late last week, when Yahoo made changes to DMARC, or the specification they use to determine whether incoming email is really from who it says it's from. In particular, the email's From, Reply-to address and sending IP address are big factors in determining the authenticity of an email using DMARC, amongst other things.

As a result of these changes, if Yahoo! Mail sees that an incoming message from one of their email domains that hasn't actually been dispatched from their servers, then it will be bounced, or dropped automatically - and never make it into the inbox. From here on in, people that use a @yahoo.com address in their campaign and sender details will likely see a 100% bounce rate from subscribers with @yahoo.com addresses - not to mention other providers who follow Yahoo's example.

While the straightforward advice here is to not use a Yahoo! Mail address in your campaign and sender details, we strongly suggest not using any free webmail addresses. Gmail already flags emails sent from @gmail.com addresses as phishing attempts under similar circumstances, so it likely won't be long before all "from themselves, but not from themselves" emails are treated with the same scrutiny by other webmail services.

But I'm using a webmail address - what should I do?

The best deliverability advice we can give is to use an email address with a non-webmail domain name. It’s still okay to have this domain forward mail to a webmail address; alternatively, you can use Google Apps to send and manage email from this domain directly. Email authentication can also prevent delivery issues. For detailed recommendations, we highly suggest reading our Guide to Landing in the Inbox.

Finally, while this is isn't an issue that's specific to Campaign Monitor, you're welcome to get in touch with our team if you have any questions regarding email authentication, changing your sender details and the like - we're always happy to look at your campaigns and provide advice.

    I have a client who refuses to use an email address other than her ancient @att.net email address. This information might help me change her mind. She has nearly 5000 opt-in subscribers from her website and maintains the notion that she would not be able to respond to all the inquiries that would result from an email blast. I love my clients… but man, sometimes they can drive me crazy! Great post. Thanks!
