Welcome to the community, @Sanabria! This post discussed previously should help you solve your issue:

Kobo form not accepting email addresses with multiple periods (in a regex)

Hi @esario and @nat, Following regex will let you add more than one dot after the initial dot. It won’t limit to 2 dots. regex(., ‘^[A-Za-z0-9._%+-]+@[A-Za-z0-9-]+[.][A-Za-z.]{2,}$’) Best,
