I have more than one Twitter account, a couple personal related ones and @TheMarketaire that I use for this site.
For those of you who have multiple Twitter accounts, you’ve probably noticed that you’re unable to use the same email address with other accounts. If you try it, Twitter will shoot out the “Email has already been taken” error. A pain, I know.
But don’t fret, there’s an easy solution! If you’re using a Gmail or Google Apps email address then you’re in luck!
With Gmail you can add a dot (.) anywhere in the username end of the email and all emails sent to the dotted email will still end up in your Gmail inbox. For example, if I had email@example.com, any email sent to firstname.lastname@example.org or email@example.com would still find its way to my inbox, as Gmail ignores periods in the username.
I think you know where I’m going with this, but I’ll continue on to be thorough.
Twitter considers firstname.lastname@example.org and email@example.com to be two separate email addresses even though they both direct email to the same Gmail inbox.
If you don’t want to use this method (for whatever reason), a second email is created automatically when you register for a Gmail account, one that uses the googlemail.com domain.
So if you have two accounts on Twitter, you can use the Gmail email with one and the googlemail email with another.
