So i’ve set up a custom domain to use with protonmail and was curious if anyone else uses the catch all in this manner.

I was thinking that when a new account is created on $website I would use a custom email address that would then be caught by the ‘catch-all’. So say the domain is catata.fish, and the website is target.com, then when signing up I would use target@catata.fish. Previously when using gmail I would use email+target@gmail.com.

Does anyone see any issues doing it this way? Thanks!

    Don’t use + as delimiter. It is an email standard for alias and will send the email to the none alias version inbox. Better to use a different delimiter, like minus, -, instead. Not sure how easy it is to do with Proton.

    I keep a whitelist of email addresses allowed, the rest is therefore blocked. This means I can’t send to random@example.com and get to the inbox.

      huh, I never knew you could use delimiters other than +. That is a good thing to know.

      I think I’ll just stick with using aliases with a delimiter.

        You can’t. It is not an official alias. That is the point. So they will be seen as separate accounts. But I forward everything to he same account. Have to configure it for every email address. This way I keep a whitelist.
