Email Worker Professional

Email Worker Professional is a lightweight and portable application that verifies the validity of any email address. It comes packed with an intuitive interface and features, accessible to all types of users, regardless of their skill level.

The advantages of a portable app

Since installation is not a requirement, you can drop the program files anywhere on the hard disk and click the executable to run. As an alternative, you can save Email Worker Professional to a USB flash disk or similar storage unit, in order to run it on any workstation with minimum effort.
What's more, the Windows registry is not going to be updated with new entries, and leftover files are not kept on the hard disk after removing the program.

Add addresses and view results in the main window

Importing emails into the workspace is done by loading files with multiple addresses (TXT, CSV, XLS, DOC, XML) or by manually inputting them, one email address at a time. It is possible to import multiple documents at once.
After starting the validity verification sequence, Email Worker Professional displays the email address, result and details for each item. This list is cleared with every new operation.

Save results, view history and adjust the number of threads used

However, Email Worker Professional records history and gives you the possibility of exporting the submitted email addresses (successful, failed, or all) to a plain text document. It also lets you select the number of emails per file (or unlimited), and automatically opens the target folder afterwards. Unfortunately, you cannot set a custom saving directory.
From the Settings panel you may adjust the number of threads and time interval, reset emails by marking them as “unconfirmed”, as well as delete them from the database (successful, failed, or unconfirmed).

Bottom line

The application is low-demanding concerning CPU and RAM, so it does not interrupt normal activity. We have not come across any issues in our evaluation, since this program did not hang, crash or show error dialogs.
All things considered, it becomes pretty clear that Email Worker Professional is a useful piece of software when it comes to verifying the validity of multiple e-mail addresses, regardless of your previous experience with the IT world.
