Gmail and Yahoo sender rules, in plain words

What the big inbox providers now require, and how to stay in the inbox.

Couple reading an email on a phone

Gmail and Yahoo now expect every sender of regular email to follow a few rules. Here's what they mean for you.

Prove the email is really from you

Your domain needs records called SPF, DKIM and DMARC. They're like a signature and a return address that inbox providers can check. Hapi Mail walks you through adding them.

Make unsubscribing easy

Every marketing email needs a one-click unsubscribe, and requests must be honored within two days. Hapi Mail adds it and honors it instantly.

Keep complaints low

If too many people mark your email as spam, providers start filtering it. Only email people who asked, and make it worth opening.

What to do this week

  • Set up your sending domain.
  • Remove addresses that bounce.
  • Make sure every email clearly shows who it's from.
