I wish OP had provided some actual A/B registration fall-off data. For me client-side validation is more for catching user error than to do any actual "validation". That's always been the job of confirmation email.
I think there is going to be a very low percentage of users who will register again if they don't receive a confirmation email, unless you're giving away free iPhones. Granted regex can not catch most of the user-generated errors, but it can catch a few which could still increase you registered users.
To that point a better UI/UX (font size, spacing, etc.) might do a better job in lowering typos in email.
- davidcelis 13y agoI wish I'd done that too, in retrospect. I could obviously have done much more research around my opinions, and there's one use-case in which what I'm advocating simply does not work: when you are _paying_ to send those emails. In that case, yeah, you're gonna wanna do some validation.
