What happens if you misspell your email address?
Some will (gasp) silently drop the mail and take no action on it. More commonly, though, is that unless you typed a real email address (i.e. "[email protected]" and "[email protected]" both exist) you should receive a bounced message indicating that the mailbox does not exist.
Can an email account be recovered?
If you deleted your Google Account, you may be able to get it back. If it's been awhile since you deleted your account, you may not be able to recover the data in your account. If you recover your account, you'll be able to sign in as usual to Gmail, Google Play, and other Google services.
