MailDump Verifier for Firefox

Generally speaking, the validity of email addresses can be measured via several techniques and, if you store them in an internal database, proprietary algorithms. Then again, sometimes, you may stumble across various addresses while browsing the web and want to know immediately if they are legitimate.

MailDump Verifier is an extension for Firefox that provides you with a quick way to determine the validity of an email address in a jiffy.

As you probably guessed from its name, the extension has the role to validate email addresses as you go. Consequentially, you can eliminate the invalid ones from your list or database and hence, reduce bounce rates while saving time, effort and money at the same time.

It is worth mentioning that the addon uses several criteria to determine whether an address is valid or not. More precisely, the tool checks for whether the address is deliverable, has a valid format, it is disposable, the server status and its role. It checks the email domain, email user and whether it is coming from a free service.

While the utility includes a bulk option, you should bear in mind that it has a small bug if you choose to type the addresses. Namely, you are not able to type in more than 5 addresses at the moment. Then again, if you collect the emails using Mail Dump, another Firefox extension from the same developer, you seem to not experience this inconvenience.

MailDump Verifier for Firefox could come in handy for marketers or any other professional who needs to manage a database with user data and that would like to clean it on the go. Nevertheless, the extension could be just as useful for any professional who receives unsolicited emails that they would like to verify.
