E-mail Validation Software

Save time and money maintaining clean mailing lists and checking the validity of recipient's e-mails addresses...

If your database contains incorrect email addresses, this disadvantages you in two ways. First, you have to put up with annoying 'undeliverable' messages. And second, you lose the ability to communicate by email with your contacts. Email Verifier checks the validity of your email addresses without actually sending messages.

eMail Verifier is your powerful solution for the standard "message delivery error". Email Verifier verifies every e-mail address from a given mailing list, allowing you to determine 80-90% of "dead" email addresses.

eMail Verifier works on the same algorithm as ISP mail systems do. Addresses for e-mail are extracted from a Domain Name Server (DNS) and eMail Verifier tries to connect with SMTP-servers and simulates the sending of a message. It does not send the message though - eMail Verifier disconnects as soon as the mail server informs the program whether the address exists or not.

eMail Verifier is a very effective piece of software that can verify over 10 e-mails per second . It can verify single e-mails or huge lists. eMail Verifier is multithreaded, providing high speed verifying.

eMail Verifier is available in English, German, French, Spanish, Italian, Dutch and Russian for both macOS and MS Windows systems.

WIDELY COMPATIBLE - eMail Verifier simulates the sending of a message and checks the server response very carefully. The algorithm used to clarify the responses is the result of years of testings.

BLAZING FAST - eMail Verifier is a very effective piece of software that can verify over 10 e-mails per second . It can verify single e-mails or huge lists. eMail Verifier is multithreaded. It provides high speed verifying and allows you to balance the domain lookup load between several DNS (Domain Name) servers.
EASY-TO-USE - eMail Verifier is an extremely easy-to-use and straightforward software. You just have to drop your file(s) directly over the eMail Verifier main window. eMail Verifier verifies every e-mail address allowing you to determine 70-80% of "dead" email addresses. Email addresses are verified individually using a set of 80 built-in rules.
SECURE - We have created a system that only flags bad emails. If eMail Verifier is not 100% sure then the address is mark as 'Looks Good' or 'Looks Bad' and you decide what to do. The software tries to clean the list its best but without taking any risk of deleting valid emails.
CUSTOMIZABLE - The eMail Verifier output is fully configurable through a preference panel. You can ask the software to format the results as you need or to create aditional output files.
LOCALIZED - eMail Verifier is available in English, German, French, Spanish, Italian, Dutch and Russian.

Once you have verified your list you have the choice between saving the valid addresses and send your message directly to it or saving the bad addresses in order to clean your original list. In fact, if you use MaxBulk Mailer, you can name your file "DELETE" or "UNSUBSCRIBE" and drop it over the software recipient list. All addresses from the file will be removed or unsubscribed from the list in a snap!

eMail Verifier has proven helpful to us. We have more than 7,400 e-mail addresses for our members, and they don't always tell us when they change addresses. eMail Verifier also catches obvious typos, and it does it a lot faster than I can scan a list of e-mail addresses. eMail Verifier may not be for everyone, but it works for us, and really cuts down on the number of bounced messages when we send out notifications to our members. – Greg Raven

The software performs a series of checks to validate every e-mail address including, a syntax check, an e-mail address domain check and finally an e-mail address validity check with the server. All those checks take time to perform and sometimes a user may wonder how much time he will have to spend on this, especially when testing big lists. They can dramatically affect the overall validation speed when verifying a list of e-mail addresses depending on its size.
