eMail Verifier is a Mac program designed for people who work with emails often and wish to determine if the email addresses within their recipient lists are valid or not. The application features a user-friendly interface, immediately gives you the answers you need, and uses minimum CPU resources while operating on your desktop.
You can enter one email address or import a document that contains multiple addresses. All you need to do is to import the data you wish to analyze and click the Play button from the upper-left side of the interface. The application will immediately let you know which of the analyzed email addresses are valid or not.
Another good aspect is that you can export the scan result to your local directories as a TXT file. The app also enables you to undo as many Preferences files alterations as you like.
The only bad aspect that's worth mentioning it's the fact that the program occasionally runs slow. This usually happens when importing files that contain email addresses.
Still, this application provides you with a quick and simple way to verify if your email addresses are valid or not. So, I'd say it's worth giving it a try on your Mac.
