Domain names for catch all email aliases (lemmy.world)

OQB: @spinning_disk_engineer@lemmy.ca

I'm looking into getting some domains for email, so I don't need to use the same few addresses for everything. In doing this, the domain name itself becomes the identity, but it's also entirely arbitrary.

What is a good method to choose domain names so that they look more or less normal? Catch all addresses can of course be detected in SMTP, but the idea is just to not look suspicious. Would anyone be comfortable sharing the constructions they use? (though not the domains themselves, for obvious reasons) Should I use subdomains for the things that can safely be correlated, (as spam defense) or is it better to only use different mailboxes on one domain?

basic feature of most providers...

ive been customizing the name@ for every contact/use so I know exactly who sold the address goin on 20 years now.

side bonus of no address cross-matching compromised systems.

its awesome

I do exactly this with a cheap entry tier Google Workspace account tied with a domain for email

I forget the exact setting name in the console for this, but it's a built in feature and works exactly as you'd expect, I can make up whatever I want on the spot before the @ and it'll deliver to my designated inbox

I'd imagine a similar feature would be available at any business-type email provider

There have been a few places that catch it and "error" the email if I try to use the services name in the email, but it mostly makes it through everything I've used it for

The only service I've had a problem with like this was Netflix. They let me sign up with netflix@domain in 2015, but some time in 2018, they stopped sending me emails. When I wanted to export my data and cancel my account, I changed it to netflicks@domain and that seemed to work.
