It's ok, I'm using the free tier and regularly delete and set up new addresses. Works for the really spammy stuff.
I also good a paid account with addy.io where I added one of my domains, that's something I use for more legit services where I want more control about the username, so I can always use something like their.domain.tld@my.domain.tld and never have to worry about finding obscure usernames. And if I stop using a certain service, I can just switch off the alias and never bother about retention crap.
I second Babylon Berlin, it's amazing.
Other than than that I've recently enjoyed Vortex (French) and Public Enemy (Belgian), both on Netflix.
