Why is AMP not rendering?

Last updated February 19, 2024

There are times when AMP email fails to render. This can happen because of multiple reasons-

Your sender email is not approved- You need to get your sender domain approved before you can start sending out AMP emails. Learn how to get AMP approval on Mailmodo
Unsupported email client- AMP is only supported on Gmail, Yahoo, Mail.ru and FairEmail. If you are viewing the email on any other email client like Apple mail or Outlook, then HTML fallback would be shown.
Outdated or Unsupported Browser- If the email recipient's browser is outdated or they are using a browser which does not support AMP (like Microsoft edge), content might not display correctly.
Recipient settings- If the recipient has turned dynamic emails off in their email client, then AMP will not render. Learn how to enable dynamic emails on Gmail .
Email size exceeds 200kb- If the AMP email exceeds 200kb, then AMP will not render. If your email exceeds the threshold, then you will see an error under template suggestions .
Technical issues- If your email client shows an invalid AMP message, then contact your customer success manager or reach out to us via the in app chat to resolve the issue.

If you are testing AMP emails and your sender email has not received AMP approval, use Mailmodo's pre approved default sender email.
Alternatively, you can manually enable dynamic emails for your sender id by navigating to settings>dynamic emails. Note that the email must be SPF, DKIM and DMARC authenticated.
