Does the cloud community offer any type of MX server to use in conjunction with my top level domain?

Or does having an email address with the domain require self hosted?

Needing an email "support@viziongm.com" to setup with Commerce.

You can set that up using the cloudflare, go into the dns settings.

Woops, disregard, just realized what I said was just for the address, not the mail server.

Thanks to @Paul.F I got this sorted using Mailgun

Noooooooo, Mailgun has POP3/IMAP disabled

Screw it, I'm making a Mailgun Pipe for Nexus Support Requests.

All done: https://community.invisionpower.com/files/file/7799-mailgun-pipe/ - probably take a bit for them to accept.
