Gmail or Yahoo are turning your email away

The biggest email companies have changed their rules. Email that can't prove where it came from is now sent to spam, or blocked.

Updated · senderframework.com

Signs this is happening to you

  • Emails to Gmail or Yahoo addresses bounce back.
  • The notes that come back mention new rules for senders.
  • Email to some people arrives, to Gmail users it doesn't.
  • Your newsletter numbers dropped from one month to the next.

Why is Gmail blocking my emails?

In 2024 Google and Yahoo told everyone who sends email to their users: prove your email is really from you, or we won't deliver it. Others have since done the same.

Many businesses never heard about it. Their email just started to go missing, and the notes that came back were full of words no one could follow.

I passed before. Why not now?

The rules are checked on every email, every day. Your settings have to stay right as your business changes. A single slip and your email is back on the wrong side of the line.

What we find that others miss

These are small things. Each one is enough to send your email to spam, or let a fake through.
