You can append to your existing e-mail address in various ways, and this could be pretty useful for seeing who leaked your e-mail address to spammers. For example, for your bank, give them the address [email protected]. Then, if spammers send to that address, you can quickly see where they got the e-mail address from!
I’ve tested it with Proton Mail, and it works in exactly the same way.

that very much depends on your email provider. while it works in Gmail and ProtonMail, it doesn’t on Tutanota. just double check before you start using it.
also some websites don’t support the + sign in an email field, and others have apparently learned to ignore it and everything that comes after it. something like Anonaddy/Simple Login/Mozilla Relay would probably be more likely to work. they generate a unique, random e-mail address that you sign up with, and then forward the emails to your main inbox. but then again, some services don’t accept emails from their default domains as valid/safe.
E-mail providers could configure another character for subaddressing, broadly accepted in forms, but they stick to this plus sign sadly.
I think about trying to buy a domain name, and playing with catch-all and ignore rules to avoid spam while creating a custom subaddressing setup on a custom domain. Source: this Mastodon post https://chaos.social/@silmaril/108878671259313909
