Mailcheck.js is a Javascript library and jQuery plugin that suggests a right domain when your users misspell it in an email address. When your user types in “user@hotnail.con”, Mailcheck will suggest “user@hotmail.com”. Mailcheck will offer up suggestions for top level domains too, and suggest “.com” when a user types in “user@hotmail.cmo”.

Mailcheck helps reduce typos in email addresses during sign ups. It can reduce the sign up confirmation email bounces by 50%.

Mailcheck included default domains are yahoo.com, google.com, hotmail.com, gmail.com, me.com, aol.com, mac.com, live.com, comcast.net, googlemail.com, msn.com, hotmail.co.uk, yahoo.co.uk, facebook.com, verizon.net, sbcglobal.net, att.net, gmx.com, and mail.com. The included default top level domains are com, net, org, info, edu, gov, co.uk, and mil.
