# Check the domain of an email address by regex

The following Google Apps Script is designed to use a regular expression (regex) to confirm if an email address domain matches one we specify eg: @hotmail.co.uk, @gmail.com, @outlook.com

I developed the code so I could screen email addresses to make sure they only came from within the institution – otherwise it would have broken the tool I was developing for creating Zoom meetings. The email addresses in this example are all stored in one cell in a Google Sheet and are separated via a comma and a single space.
