I'm hosting a forum at
subdomain1.example.com. For activation emails etc, I have a Mailgun server at
mg.subdomain1.example.com. The Mailgun server can only send emails, no receives, so I bought an email plan from GoDaddy and installed this at domain.com. Then because I like it, I added MX records, so I can access the emails through Gsuite.
But once I started with the Gsuite setup, I wondered if I needed that GoDaddy email plan at all? Could I have set it up without it?
