What is RegEx Validation (Regular Expression)?

RegEx validation is essentially a syntax check which makes it possible to see whether an email address is spelled correctly, has no spaces, commas, and all the @s, dots and domain extensions are in the right place. 

Why does it matter? 

RegEx validation is required for security purposes and to ensure that we have the best possible user experience for our customers. 

How does it work? 

There are three places that regex validation will be applied across our service. 

  1. AdRoll Sign-Up Form 
  2. Settings: When a user email is updated 
  3. Settings: When a new user email is added

What does it look like? 

Hopefully, you won’t ever notice this syntax check but if you do the error message will look like below and read: 

Please enter a valid email address.

  • Include an “@” in the email address
  • Make sure there are no spaces or commas 

If you get this message, please just re-enter your email address and make sure that all the information is correct.
