[e-mail] [e-mail] [e-mail]

Unfortunately, more and more services are rejecting + e-mail addresses. Either ignoring them, or flagging them as an error.

While it's perfectly within the RFC, companies are catching on to the trick.

(3M, I'm looking at you!)

Gmail gives you another option - separate using dots.

[e-mail]

The number of options is of course limited but it's still recognized as a separate address while still coming into the same inbox

I've built a few registration systems and always normalize email addresses (remove local part, de-dot gmail addresses) at signup and login.

It helps users who keep trying [e-mail] when they signed up with [e-mail]. Also is pretty good at preventing mass signups using tricks like this.

How do you know where the local part starts? Google uses '+' but nothing stops you from using '-' as a delimiter if you're running your own servers.

Also, how do you deal with spam filters that are designed to spam anything without a local part? Or is this only done to "well-known" domains like gmail.com?

>if you're running your own servers.

This is enough of a threshold probably.

[apexalpha]

Actually [e-mail] would work too, since it fully ignores dots. So the options are just as (not) limited as anything a + can add.

It's within RFC, but they all lead to one email inbox so you end up being able to manage multiple third-party accounts from a single email account. It's recommended to not reject these, but strip them: https://gist.github.com/judge2020/af8fb9cd2ac165462d44de4e58...

Recommended. By google, who just played loosely with the email-spec.

How rich.

? You can store e-mail messages based on the local part of the address however you want. It's basically just an alias.

[reaperducer]

Yes, I know that. And as I mentioned, companies are still rejecting these addresses anyway because they know people are using them to identify and filter spam.

This is why I use a catch-all on my own domain with a blacklist for companies found sharing or leaking the email address I gave to them. Fastmail makes this really easy to set up and their web interface also lets you set the From address to anything on the domain.

Years ago I locked myself out of my Amazon account. Since I really wanted to keep using the same email account (and I didn't care about Amazon history, nor did I wish to go through an official account reset) I resigned up using a +suffix. I'm still amazed the second account was able to be created, though it's possible it's no longer allowed since this was around 2005 or so.

[ficklepickle]

Still works.

I made a +suffix account so I'm not buying stuff on amazon with my AWS account.
