What I want to do is to validate an email address with exact gmail or yahoo word and I have tried the following but failed:

/^[a-z0-9._%+-]+@[^gmail$.-]+\.[a-z]{2,}$/

suppose if anyone mistakenly tried to sign up using [email protected] or [email protected] or [email protected] or something like that. How can I validate that??

  • Why Gmail specifically? What are you trying to achieve? There are lots of edge-cases such googlemail.com vs gmail.com – Jakg Sep 10 '20 at 14:11

For regex to validate email you can refer this.

If you want a simple validator to allow only email addresses that contains @gmail as part of it and allow only letters,numbers,dot and underscores in user name, you can use below regex.

^[a-z0-9._]+@gmail\.[a-z]{2,}$
