This software validates e-mail addresses, but it requires an extra step to check more than one address at a time. E-AddChecker's basic interface is uninspired but very easy to follow. You can verify single or multiple addresses, but there's no way to build or import a list directly into E-AddChecker. Instead, you must create a text file of e-mail addresses and locate it with the program's standard browser. Results are saved in a text log file in a directory of your choosing. E-AddChecker returned accurate results, but an import option to more easily bring in multiple addresses should be the next step for the app's programmers. There's a 15-day trial limitation for this relatively inexpensive application, but users short on time may balk at its do-it-yourself approach to list creation.
From SunDevils Soft:
Nowadays, we are not sure the email address provided by others is valid or not. E-AddChecker provides the function for user to check whether it is a valid email address. It provides single email address checking or multi-checking at once. User could update the invalid email address from their mail list. The E-AddChecker 1.5 enhanced the language support. Now it supports English, Traditional Chinese, and Simplified Chinese.
