I am creating a website that would need to only allow some specific email addresses to signup (for example "firstname.lastname@example.org"). Do you guys know of any wordpress email confirmation plugins that would allow me to do that?
To clear some confusion: What I am looking for is only allowing some email addresses (for example all emails ending in @unimail.co.uk), I don't want to have to write down all of them independently. I don't really know how to code php so it would be super helpful if someone could help. Once again, sorry for the confusion created with the first question.
