You can integrate this with Bitwarden to auto generate email aliases too

Step 1: drop gmail

Step 2: get proton mail and activate simple login or use one of the alias slots they give you (or both!). Enjoy.

Optional step 3: Use Firefox relay on top if you really want to go wild but I find this gets folks turned around when layered on top as well. Great for burner/1-time use emails though.b

That used to be my go-to method but I found it works less and less. Places know the gmail tricks and auto-strip them out of the address.

Started using Proton's Hide-my-email and never going back. It's time to move away from google anyways.

I used to use that approach, but found in the last several years more than half the web sites I use reject email addresses with “+” characters.

I even use several sites that used to take those addresses just fine now reject them. That made me wonder if some common JS package for parsing email addresses got changed.

That is not a standard mail feature, it won't work with all mail servers and not all that do have it use + as the separator.
