This can add up quickly if you’re the kinda person who flings together an experimental site and lets it run its course. For example say 3 emails per site (info@, no-reply@, and your-name@) and 10 various small sites per year.. starts to add up.
Would be awesome if there were an alternative that you pay, say $10, and get as many email addresses as you can be bothered to set up.
I have absolutely no clue how the underlying economics of email services work, so I presume what I’m hoping for isn’t feasible.
