I hope nobody uses this for anything serious. I run my own domain and use <category>-<service>@<mydomain> to have a unique email for everything I sign up to.

I have no email address that this counts as anything other than "risky".

If this opts me out of marketing mail then that's probably a good thing, but I hope nobody puts a password-reset or security/billing notifications behind it.

I’ve been doing the same thing for years and haven’t had any trouble except for Mailchimp. Their overly-clever validation decided [e-mail] is a shared email account (it wasn’t going to be) and blocked me from using it. Their email support apologized but said they couldn’t fix the false positive, and that they hoped the email I used instead wasn’t reflective of my opinion: [e-mail].

Do you have a personal set up for managing these emails and disabling the bad ones? or are you using something like 33mail? Just curious.

[DistressedDrone]

Why would that even be a problem?

[rudyfink]

Would you mind sharing your experience on how well that has worked for you? Has the complexity of maintaining different addresses been a problem?

I ask because it is something I have always thought about, but I suppose I kept hoping a service would come along and magic the solution for me. Kudos on making it happen!

I'm not OP but I do something similar, which I can describe. I don't whitelist addresses, I have a domain with a catchall account. So I make up addresses as needed. When I want them to die, I add them to a ruleset on the server that punts them into the bit bucket.

So far it has been really great. Easy, effective.

Edit: Like the other reply you got, I use FastMail for this service.

Not OP, but I just accept wildcard *@mydomain and give out a unique name for every business. Works very well and I blocked a few businesses by which do not allow for opt-out and/or shared my address with others.

This is easy to do with the Alias feature of FastMail.

There is a service for that: https://anonaddy.com/

I've used it briefly for testing purposes and I have no complaints about it, it delivered what I expected with no hiccups.

I did it for ages and eventually stopped. It gets awkward when you have to deal with customer support people and I never caught any spammers via the method anyway. Difficulty wise it was trivial since all emails hit my main address.

[prashantsengar]

I use anonaddy for this. A generous free plan, really feasible paid plans, and is open source so you can self-host it as well.

[Supermancho]

I use <mynick>@<signupdomain>.<mydomain>

[nuker]

I just disabled “load remote content” in email clients, stops spam pretty reliably.

[madars]

This looks fantastic --- can you share some tips of setting it up?

[mkr-hn]

Somehow my domain that I've owned without interruption for ~20 years got on a list of throwaway email services.

[thebeefytaco]

Glad to see I'm not the only person who does that! Great way to catch those who share/sell your email and to set up filtering.

[SilverRed]

I did this for 3 years and did not find a single case of spammers using one of the emails. All spam was from the sites I signed up with. Email spam filters catch spam for you.

Couldn’t the seller just remove the prefix from all emails before selling them?
