There's characters missing[1] and the tld is too short[2]. And even if that's fixed, we still don't match internationalized addresses or actually validate that the e-mail address exists. You're probably better off with something like...

   if "@" in email and "." in email.split("@")[1]:
       send_verification(email)

...but you should probably also check for common misspellings like "gmial.com" etc.
