There are plenty of times when you might need a new Gmail ID. A lot of websites and subscriptions have deals aimed at new customers, and this is particularly true with streaming platforms. So if you're previously subscribed to something and want to access deal pricing again, the logical thing to do would be to just create a new Gmail account.
But you don't have to do that. Did you know that Gmail doesn't recognize any dots in an email? So if your ID is [email protected], then if you write [email protected], [email protected], or [email protected], Gmail won't see a difference — as this 2008 Gmail blog post clarifies. In fact, you can include as many periods as you want, and you'll still get mails delivered to your primary ID.
