Which providers support AMP (Gmail, Yahoo, Mail.ru)?

And Here's the honest list. Gmail was the first to support AMP and has the best implementation. Both web and mobile apps render AMP emails, though senders have to register and get approved first. Yahoo Mail added support in 2019. Mail.ru, a major email provider in Russia and Eastern Europe, also supports it.

That's it. Everyone else doesn't support AMP yet. Outlook (desktop and web), Apple Mail (all platforms), and most other clients simply don't render AMPHTML. Depending on your subscriber base, this means 40 to 60 percent of your audience might never see your interactive email. They get the HTML fallback instead. That's why your fallback HTML isn't optional. It's your actual production email for anyone not using Gmail, Yahoo, or Mail.ru.

So before you commit to AMP, know your audience's email client breakdown. Pull a sample of your recent email opens and see what clients people used. If 70 percent of your opens happen in Outlook and Apple Mail, AMP doesn't move the needle. If Gmail dominates your audience and your use case aligns with what AMP does well (forms, real-time updates, in-email actions), then you've got a real opportunity. Analyze your own client distribution before deciding.

Not sure how to extract that data from your ESP? Most platforms show email client stats in their analytics.

The goal is knowing whether AMP will actually reach your people before you spend weeks building it.
