Is a custom domain for email a bad idea for security?

In terms of personal email security for my banking and other services, should I use a custom domain like [example.com](https://example.com) that would have just one email address associated with it, [[email protected]](mailto:[email protected]). Or, is it more secure to use a service like @gmail.com?

I like custom domains, but seems like that could be a bad plan even though I have reasonably good security practices for my custom business domains. Better to blend in with a generic email domain and not stand out is part f my theory.

I’m leaning toward using a protonmail service account because of what I’ve read.

Opinions are apprectited.

Only difference in my opinion is if you are managing your own email servers, you will, of course, have to manage the security of those servers.

Custom domain is not a problem if you redirect it to gmail or protonmail : the security and infrastrure is managed by gmail / protonmail, but your front adress is on your own domain, great if you want to switch email providers – let’s say in 10 years – and keep your email address.

The drawback : for both gmail and protonmail you must pay premium like plan to get custom domain.

You can have your own custom domain and still use a service like Office 365. I think the basic plan is $6/mo and you get use of word/excel for free with your subscription as well. Lots of other services like that. Don’t run your own mail servers, unless you know exactly what you are doing.
