Set up a filter? Did you ever try to contact the institution where the emails come from?

Yes, I do have it filtered. And yes, contacted all the institutions. They don't bother at all in updating their records. And these are banks and other financial institutions. One would think they'd take the integrity of their data more seriously.

Set it up to forward to their support e-mail addresses...

I have been getting financial emails from several people for many years at my GMail ID. They apparently have given my address but without the dot. But what mystifies me is how these people keep going for years without ever realising they aren't getting account transaction emails (from their banks), notifications of stock trades, even OTP emails etc. How is it possible for people to use these services for years withou…

There's an xkcd for everything. Sure, that's probably my email address.

If you use the + character (e.g. `firstlast+subscriptions`) it'll still arrive to your `firstlast` inbox, but will allow you to filter it more meaningfully.

I've been using this trick for a while (usually 'firstlast+per_service_identifier') and I've encountered more than a few systems which erroneously claim that any email address containing a '+' is invalid.

That's why I now own my domain, and added the first([\.-]suffix)?@last.tld -> first@last.tld mapping at my provider.

For selfhosting, there's `recipient_delimiter = +-.` in postfix' config. [0]

The most infuriating ones are those where you can subscribe with the '+', but the unsubscribe function errors on it.

You could encode the service_identifier in a pattern of dots around the letters of firstlast for cases where the '+' is not allowed. But that's probably hard to do in a way that's easy to encode on the fly, unless you already know morse or something similar.

Same. The ones that surprise me are the credit card information or cell phone plans. I was able to contact the phone company and tell them to remove my address, but the credit card was an exercise in frustration. You can't get through without account or personal info. I just mark most of them as spam these days.

In theory, providers/servers should ignore everything from the + to the @ so that should work just about everywhere else. And since most forms don't filter that out, you can make numerous "unique" addresses connected to a single one. Now odds are, someone is going to respond with the one service where the + becomes significant..

> providers/servers should ignore everything from the + to the @ Why? I'm not sure it has ever been a standard and it's certainly not a default implementation for most providers?

A quick google search returns https://www.cs.rutgers.edu/~watrous/plus-signs-in-email-addr... . Although not standard, its use is "legal"

I have used it all the time over a dozen years, both for site-specific email addresses and also for having lots of handy test email addresses in my personal app development. Often I just wish I had been more disciplined about using it even more for site-specific addresses, but fortunately more websites about friendly about unsubscribing these days.

Then why did they allow someone else to create an email like mine without the dot and I even get the occasional mail addressed to them. This is really shady, specially for an important service like email.

They didn't. You get email because somebody either typo's their similar address or they simply think that's their address when it isn't.
