Getting newsletters into the inbox

What your deliverability score means and how to improve it.

Updated September 30, 2026

The Email page shows a deliverability score once you've sent newsletters from your domain. It's the share of emails accepted by readers' mail providers.

To keep it high

  • Make sure SPF, DKIM and DMARC are all verified on the Email page.
  • Only add people who asked to subscribe. Never import bought lists.
  • Remove members who haven't opened anything for a long time.
  • Use a clear sender name and subject lines that match your content.
  • Keep a steady schedule; sudden large sends from a new domain look suspicious to mail providers.

If your score drops below 90%, the Email page flags it. Contact us and we'll look at the bounce reasons with you.
