Gmail rejecting email as spam after moving to Cloudflare

Website, Application, Performance DNS & Network
1

What is the name of the domain?

croquetbooking.com

What is the error number?

N/A

What is the error message?

The sender hasn’t authenticated this message, so Gmail can’t verify that it actually came from them.

What is the issue you’re encountering

Gmail classifying mail as spam

What steps have you taken to resolve the issue?

None - I don’t know where to start!

What feature, service or problem is this related to?

DNS records

What are the steps to reproduce the issue?

Since migrating to Cloudflare email sent by my application ends up in Gmail’s spam folders. This never happened before migrating to Cloudflare. I imported my DNS records and accepted the defaults suggested by Cloudflare. My application sends mail using AWS SES. I’m stuck!

Such authentication failures needs to be fixed by the sender of the message, together with their email provider.

This phrase does make it sound like you’re the actual sender of the problematic message, and that it was sent through your set up with AWS SES?

Is that correct?

Did you verify that you had copied over all the DNS records to Cloudflare, that had a name containing “_domainkey” on your old DNS provider?

And assuming any of these are with the type CNAME, that they have their Proxy status set to Unproxied (:grey:) / DNS-only?

Many thanks. Copying those three CNAME records over to Cloudflare solved the problem.
