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

It works on the same algorithm as ISP mail systems do. Addresses for email are extracted from a Domain Naming 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 more...

I had variable results depending on the provider:
- gmail.com: no way! I've tried even with my own address and after the regular ten trials it gives up
- wanadoo.fr: ditto
- free.fr: some address gives instant positive results, others seem to block the app (the button seems not being clicked, but then after a while, you've got the result; sometimes, while having had a positive result I had a "ding" warning from the app in the background and an error message while I wasn't using it...)
- hotmail.com: immediate positive result even with any address I could imagine such as ghftrei159qsdfqsdfqsdfqsdfqsdf@hotmail.com (I can't be sure it doesn't really exist, though... ;-)

Well, that's enough for me to think it's not reliable, if it's not reliable with every mail address and every provider.

sending a regular mail to the above tested ghftrei159qsdfqsdfqsdfqsdfqsdf@hotmail.com, I received, as one can easily verify a "mailbox unavailable" answer from Hotmail... :-)
Just test it on both eMail Verifier and your mail client.

Hkim is right, this application works great. Users here who are claiming that it doesn't work at all are wrong. One only needs to look at the details and output from the application to see that it is indeed checking each email addresses.

This application also does a great job handling the lists, it automatically finds email addresses in the lists and when you export it lets you export a cleaned list in the same format as your list. This saves time and effort, great feature.

My only complaint is the application is a little pricey for what it does. I could see it priced at $10, not $30.

Despite the previous review, I tested this one several addresses and it did work; a deliberately bogus address at gmail failed while a valid address from the same domain worked. I tried this on several spam return addresses and they could not be verified, thus they were no good.
This software has a use for people who need to verify that their mailing database is up to date. As such it is worth the money.
The other commentators that thought this app is a spam tool have absolutely no idea about how spammers operate. They would never waste their time to verify an address with such a tool.

It's not going to work. The idea of this application itself is foolish. An app could analyze each e-mail address to the extent that there's one or more mail servers attached for the given e-mail domain. But there is no way, not with even 80% certainty, for any app to find out if the given e-mail address is valid. If this app is going to send a packet to the given e-mail address, there is no guarantee that a mail server of the given e-mail address will respond. More likely, a mail server won't even respond immediately when there's no username you've specified.


There is a problem with the default rules setting. Go to preferences and uncheck all the rules which automatically produce an "okay" return if the address is in a certain domain.
After that, it will check the addresses properly.

It is understandable that some would feel this application aids spammers but my guess is that spammers use something much more robust than this. Legitimate businesses send email to their customers and clients on an opt-in basis and the customers welcome it. Since email addresses change frequently (especially when people change jobs) this application helps legitimate businesses verify the email addresses that they have on file for their customers. We have found it very useful for maintaining our customer database.

I have a problem with software like this because it is a spammers dream ... verfied email addresses.

I think this software should be removed from MacUpdate.

Disagree. If I use this app, and they (spammers) try to spam from non-existent email address then they just don't get through to me whether my address is validated in their records or not.
This is much more powerful for Spam filtering than aiding any spammers.

Just doesn't work! You can enter any user for an existing domain and it says it's good (using both method, VRFY or RCPT).

Would be great if it really worked, but I found this app to just go into an endless loop after three retries no matter what email address I gave. And because of the built in rules, any hotmail or aol address just automatically says it's good. It has a nice interface - simple and easy to navigate, but it also lacks simple keyboard control. Example: After typing in an address, you want to hit the Return or Enter key to start the search but no go. You have to hit Apple+K or click Verify to start or Hit ESC to stop a search but you have click the Cancel button.

It's nice idea with a clean interface and has potential, but currently this goes nowhere
