FAQ

What happens to my old e-mails? Not to worry. All of your messages will be retained and automatically transferred to your new account. Calendar appointments and contacts will also be transferred. You won't lose any valuable information.

How much storage space will my new account have? The current limit is 25GB, although Google continues to add more storage space so e-mail users can archive older messages rather than having to delete them.

Is my information secure? Absolutely. Just like bank and credit card websites, Gmail uses always-on HTTPS encryption to keep your mail secure, so someone sharing your favorite coffee shop's public Wi-Fi can't sneak a peek at your information.

Can I check my e-mail while abroad? Yes. Google is not aware of any country where Gmail cannot be accessed.

What if I already have a Gmail account? You can keep both accounts separate, or you can forward one account to another.
