If you accidentally type in an email address incorrectly one of two things will happen. First, if the mistyped email address actually exists the email will be delivered to that email inbox. You can try to retract the email – a somewhat technical step that varies considerably from one email client to the next – but there’s a good chance the email will simply be delivered to the address you typed. Second, if the mistyped email address doesn’t exist you’ll receive an error message stating that the email could not be delivered.
