Update thank you to Johannes in the comments. This is called Email Sub-Addressing.
I was catching up with my brother, and he showed me a pretty cool trick with gmail.
If you mail firstname.lastname@example.org (not his real email address) with email@example.com - the email would arrive at his inbox.
Not to be outdone, I tested this with Outlook, and sure enough. If you mail: john-liu+test a outlook dot com they'd arrive in my personal mailbox. You can do anything after the + character. +spam, +newspaper, +test1 etc etc.
I have no idea what this feature is called - for Gmail it seems to be called "Creating Multiple Custom Email Addresses with one Gmail account". May be this is called Email-Alias?
So this is just a short blog about an Outlook version of this feature. This works for Hotmail as well.
What is this good for?
- Test throw away emails, e.g. testing your registration process code
- Spam emails and figuring out where they came from
- Easy to set up filter rule to get rid of emails you don't want
- You should definitely have a john-liu+spam alias for signing up to newsletters.
- Doesn't work for Exchange or Office 365 email addresses.
