Tada’s email validation filters out as much as possible incomplete or invalid email addresses so that users won’t be able to simply type random text in the “email address” in order to play the game and/or receive a coupon code .
This validation is really quick and happens in less than 2 seconds ⌚. During this time, Tada uses one of your Email Validation Token to query the mail server of the user and validate their email. In case the email is not considered valid, the “email address” bar will highlight in red and suggest the email address used is not valid.
You can buy Email Validation Tokens and edit these settings under the Email Validation section in your Widget setting:
