I’m trying to figure this out from what I find on the web site, but can’t seem to. I have 3 different domains, used only for email. GoDaddy had a decent email system, but then they turned them all into Microsoft Mail, which sucks. I would want to cancel Microsoft, and have my email hosted by Proton, but all I see is that you can forward mail to proton. Can I do this, or would I have to keep paying for Microsoft Mail so it can forward to Proton?
I purchased the proton duo plan and I can confirm you can bring you own domain and use it for email. Worked smoothly for me, setup was well explained.
Most Proton paid plans allow up to 3 domains for mail:
I have proton unlimited and use it with two of my domains. I have the MX stuff pointed to proton and the A names pointed to other servers. Works great.
Edit: That means i can send and receive emails from my custom domains in proton, not just forwarding
