Hi, I am trying to include a custom validation in my survey that checks if an email address is in the right format. I am trying to check for a single letter followed by a . (dot) followed by an undefined amount of characters. I also want it to check that our domain is not included. For example address f.manchester (validates True) m.bob (validates True) mhoward (validates False) m.bob@snhu.edu (validates False) I've read similar threads where people do this with numbers but I couldn't find anything with people doing it with letters. Thanks for your help!

Use regex: ^[a-z]\\\\.[a-z]{1,}$

In custom validation add conditions like if doesn't contains "." or does not contain ".com" it throw error.
