MX/CNAME records for SES

Hi

I have an EC2 instance routed through Cloudflare and want email (via my site form) to go through my gmail account. The best approach seems to be using AWS SES (simple email service) due to various restrictions.

I’ve set this up and verified my domain but now it wants me to add 3 CNAME entries (names and values) for my DNS which is handled by CF. I currently have 3 MX entries which point to my domain hosting.

Has anyone done this before and presume i will need to remove the 3 MX entries first?

Thanks

What are the CNAME records that you are being asked to add?
