New Option:
domain1.com - for main email
domain2.com - for email forwarding with Addy.io
This is what I do (but simplelogin). I have a wildcard address (*.email@domain2.com) that let's me setup individual accounts for each service (e.g., lemmy.email@domain2.com)
myname@domain1.com is only shared with real humans or critical services that I don't want to risk dealing with the hassle if simplelogin goes belly up (I know I can move the DNS records and recreate the accounts, but at this point I have dozens of email addresses and am prone to forgetting things).
