If you’ve ever tried to sign up for more than one account somewhere but needed a second email address, the Digital Inspiration blog has the brilliant solution: taking advantage of Gmail ignoring periods in your email address.
We’ve mentioned before that you can use the “+” sign in your Gmail address to generate an unlimited number of email address variations for your same account, but some online services won’t accept the “+” symbol, or ignore it entirely. Instead, you can use the period “.” character anywhere within your email address and Gmail will ignore it, but most online services will consider it a separate address.
This way you can sign up for more than one account with the same online provider, but get your email in a single inbox. It’s a brilliantly simple solution, just the way we like them.
