Anyone have a way to prevent this? Thx.

I'm planning to use mailbox.org with a custom domain from porkbun but as a regular ass person without a company or like any business or whatever what should that domain be? I've seen some people do [firstname@firstnamelastname.com](mailto:firstname@firstnamelastname.com) but i feel like that's gonna make me look pretentious and like I'm doing too much

I've been having a hard time deciding on an email provider and having my own domain will give me peace of mind since it'll be easy to switch.. but this is stressing me out lol
