TheChecker

TheChecker can clean up your email list by removing invalid, incorrect email addresses, and removing spam tramps. You can upload a list in TXT, CSV, XLS, or XLSX format, which TheChecker can then run through to verify the email addresses, or you can check each email individually. You can also add email verification to your website by adding a line of code to the back-end. TheChecker has an email verification API, which allows you to add this functionality to your existing web or mobile application, or develop a white-label version of TheChecker app. TheChecker verifies domains, finds typos in email addresses, removes duplicate email addresses, validates syntax errors, tells you which emails will bounce, checks for temporary or disposable email addresses, and validates the existence of MX records against a continuously updated database. TheChecker works on email addresses anywhere in the world.
