Many email hosts will let you add a number or text after the email name followed by a “+” and before the “@” sign so you can create multiple unique email addresses for testing.

e.g. one of my email addresses is; I can also use,, etc.

I have tested this on 4 different hosts so far and the following allow this:

  1. google hosted emails ( and
  2. icloud (
  3. Hotmail/outlook (
  4. I also understand it works on yahoo but I’ve not tested it

The following do not allow this:

  1. British telecom hosted email accounts

I’m trying to compile a list of hosts that allow this so if you use a different host for your email (e.g. GoDaddy etc) and it works (or doesn’t), can you please send me an email at support@buildyourinternetbusiness, add a comment below or click on the support tab and leave a message?

Many thanks!
