How does AMP affect deliverability?

Here's the good news: AMP won't tank your deliverability. Here's what actually happens. Gmail requires senders to have solid authentication before they can even register for AMP. You need valid SPF, DKIM, and DMARC (with at least p=quarantine policy). This authentication baseline already signals legitimate sending, which helps your reputation with mailbox providers.

If your AMP markup has errors, or your authentication isn't up to snuff, the email doesn't bounce. Instead, the recipient sees your standard HTML fallback as if AMP wasn't there. That graceful degradation means a broken AMP won't torpedo your inbox placement. Your email still arrives. It just won't be interactive. You miss the engagement benefit but don't lose deliverability.

The second part matters more for long-term reputation. If your AMP works well and users engage with it (clicking, submitting forms, spending time in email), those positive signals flow through to mailbox providers. Higher engagement boosts future deliverability. But if your AMP frustrates people or breaks frequently, poor engagement could work against you. SPF, DKIM, and DMARC are your foundation. You can validate these with our free DMARC parser.

The bottom line: AMP raises the authentication requirements but doesn't threaten delivery. It's actually a gentle force for better sending practices. If you're going to invest in AMP, make sure your authentication is airtight first. Check your DMARC reports to spot any alignment issues. Then test your AMP template thoroughly before sending to your full list.
