Would you like to create multiple Twitter accounts and still use the same email ID with all of them. Currently Twitter does not allow that. Whenever you want to create a new Twitter account you need to use a new email account.
But using Gmail you can create multiple Twitter accounts using the same email ID? There is a snag in Gmail that you can take advantage of…although it might not work in future, but by that time you will have already created your accounts. Gmail doesn’t differentiate between email@example.com and firstname.lastname@example.org. So if you have created your Gmail ID as email@example.com or firstname.lastname@example.org, whether you send an email to the former or latter, it goes to the same email ID.
Other services, on the other hand, take them as two different email IDs. So in Twitter you can create two accounts by using email@example.com and firstname.lastname@example.org. Is that it? No, you can create more accounts by using email@example.com, firstname.lastname@example.org etc. and they’ll all go to the same email ID and you can create multiple Twitter accounts using it.
