If you're paying for Proton, you have access to SimpleLogin, which lets you make unique addresses that will forward to your real address. You can even respond from those addresses.

There are several other services that do the same thing (e.g., AnonAddy).

Create a different alias for everything using a service like:

• SimpleLogin
• Addy (AnonAddy)
• Firefox Relay
• Apple Hide My Email

Duckduckgo has an email redirect thing where you can make temporary addresses that forward to your normal one.

They offer integrated aliases via Proton Pass now.

Protonmail or Gmail.

Edit: but lately also Apple's email obfuscation service tied to iCloud. But I'm an Apple platforms kinda guy.

mail.tm is pretty nice for this. It's meant to be used as a throwaway email service, but you can also save the login credentials and reuse the email address if you need it more than one time.

I like guerrilla mail (short term email generation) but I’ve found that a lot of their domains are blocked by these sites I’m trying to sign up for >:(

I use forwarders on a domain I own that point to my primary acct.

How does protonmail make it tedious? I use ProtonPass and it creates a new email for me in one click and I dont pay for protonmail. Every newsletter or account i register uses a new email that are forwarded to my protonmail

For trash sites (random forums, free software downloads, porn etc.) that do not get my real information, and it doesn't matter if I lose the account, I just use a random 10 minute email site.

For anything where I input my personal information, or deem slightly more important, I use a catch-all address in Protonmail with my own domain.

If you're making a throwaway account or something not important you can use 10minutemail. It's a website and is free. Been using it for a while.

I use Gmail as a trash account for easy logins and proton for the rest with Gmail forwarded to proton so I never have to open Gmail itself.

Courvix, but I think signups are disabled at the moment.

I have an account with Tuta. I set it up to be able to use my own domain, so Ive created a few throwaway accts.

I use (and created) https://port87.com. It lets you use a different address for every account and keeps them all organized. It’s great for managing accounts. (And I have literally hundreds of accounts.)

One of the nice things is you don’t need to create a new email beforehand. You can give out an email address that starts with yourusername-, and it just works. You get a new label in your account that you can approve and it goes in with all your other labels.

You can also enable screening on a label if you wanna use it for real people, then it will screen new senders before you see their email.
