Incoming: Either the registrar provides a free forwarding service (e.g. Google Domains), or I have a $5 DO droplet which has a postfix server running that forwards email to a free gmail account. I create a new gmail account for each domain I want an email address with. e.g. for awesome-domain.com, I have a corresponding myname.awesome-domain@gmail.com Outgoing Depending on how much I care about the domain, I'll either setup gmail's SMTP (which shows it's using Gmail to send on the receiving end). Or I use some like Mailgun or Sendgridwith correct SPF, DKIM, DMARC settings. Usually their monthly free tier is enough to cover my needs for sending emails. I can dig up my postfix forwarding setting if you really want.
