So, I use addy.io, and I’m slowly trying to de-google my life, but I ran into a service last night that rejected my email alias: Steam. So as of now, it’s still stuck on Google.

I’m also using Tuta, but I’d like to avoid handing that address out to any online services if possible. What’s the best option here?

Here’s some ideas I had:

• Keep using that old Google address but filter specific senders and forward them to the alias I want to use.
• Set up a new email on Proton or Mailbox.org and use that to forward to my chosen aliases.

Is there perhaps a better or different way to have aliases for services that reject them?
