I think you're missing that the feature we're talking about is specifically within the $5/month option, in much the same way that ProtonMail (the one I use), also hides their catch-all option behind a higher price-point.

I'm also fairly sure that they don't let you reply as the address the catch-all was placed on, which is an important feature.

If you know any that do, that'd be great.

True, I missed that "custom domain" isn't part of the lowest tier.

The point still stands though, if you have a mail provider that supports custom domains there usually isn't a limit on the catch all aliases you can add (or a very high one). In any case it's far from being "prohibitively" expensive.

That is definitely possible with Fastmail as that's how I use it. In their case I believe that feature is called "Alias". If you reply to an email you just select with alias you want to reply from.
