What is the way to attain maximum success rate to verify the existence of an email address? Currently, I have been using the following package [npm package -> https://www.npmjs.com/package/email-verify] in my Node.JS script to validate bulk email ids, but it treats a lot of valid email address as invalid.

Agree with the comment, re: sending a verification email. I've toyed with packages that try to automate the process without involving the user, and they are all essentially heuristic in nature, yielding false negatives and/or false positives. I tried one which could not validate some university emails, because it depended on the configuration of the SMTP server, for example.
