Wanted to expand on your custom domain for an email since this is something I do to get a more professional email address to put on my resume. A lot of DNS services like Cloudflare or NameCheap will actually let you create email addresses off of your custom domain that will just forward to a different email of your choosing, and generally free or very very cheap as well. If you want to be able to actually send emails from your custom domain, you can setup a Google Workspace account with a single seat for $5 a month and have a fully hosted email solution that uses your custom domain name.
