The best way to check a misspelled email address in JavaScript

Email Spell Checker is the easiest way to reduce misspelled email addresses in your web apps and server. Used in production by companies to validate thousands of mispelled emails daily.

@zootools/email-spell-checker

Email Spell Checker is a lightweight JavaScript module written in TypeScript that suggests a right domain when your users misspell it in an email address.

At ZooTools, we validate thousands of emails daily with mailSpellChecker and it helped up to reduce by 30% bounced emails.
