Recently I found myself needing to test submissions to a form. The form required a unique email address to allow you to sign up. Luckily another developer showed me a neat trick...
If you have a Gmail address, lucky for you it can be adapted in multiple ways to appear unique. For example: Let's say your email address is [email protected]
Adding a period
You can add a period anywhere before the @ symbol.
Using the + symbol
You can add a + symbol followed by anynumber of characters before the @symbol.
All of the above examples appear as a unique addresss to the form that they are submitted to. but google will ignore the periods '.' and the plus symbol (and any characters afterwards). So any emails sent to those addresses will go into the [email protected] inbox
