Creating multiple accounts with one E-Mail address

The problem

When I was coding my first twitter bot, I ran into a major issue: I needed to register a new account for the bot, which required me to provide a unique email address.
There was one big issue with that: I had the intention of making multiple bots, just to test the capabilities of the twitter API.
I quickly realized that creating a new email for everyone of those would be really cumbersome and unmanageable after a while.

Making use of "Address Aliasing"

I quickly found out about a neat little trick called "address aliasing". What it does is, allow you to add a "tag" to your email address, without actually changing it.
For Gmail and many other services you simply add a plus sign (+) right before the at (@) and add some text between the plus and at.
That could look as follows: -->
And that's also what I did for my bot account.

Important things to keep in mind

  1. If you are using a different provider than Gmail, there may be a different syntax for doing this.
  2. It won't work for all services, as some built tag checks into their uniqueness check. For me it has worked everywhere I used it.

Are there other Email providers who support this feature?

I give this advice very often and feel bad when people don't use Gmail. Gmail being the market leder, it would be surprising that nobody copy this trick.

From what I have found, at least outlook and icloud support this feature. I think you can just search for "plus addressing ", it should pretty quickly give you an answer.

Thanks that's exactly what I was loooking for

Subadressing: Addresses of the form, using various separators between the base name and the tag, are supported by several email services, including Andrew Project (plus),[16] Runbox (plus), Gmail (plus),[17] Rackspace (plus), Yahoo! Mail Plus (hyphen),[18] Apple's iCloud (plus), (plus),[19] Proton Mail (plus),[20] Fastmail (plus and Subdomain Addressing),[21] (plus),[22] Pobox (plus),[23] MeMail (plus),[24] MMDF (equals), Qmail and Courier Mail Server (hyphen).[25][26] Postfix and Exim allow configuring an arbitrary separator from the legal character set.[27][28]

Also nice to mention is that gmails are ignoring dots "." inside the username of the email. For example is the same adress as in gmail, but for third party auth its a new mail.
