How to clean your mailing lists with eMail Verifier

eMail Verifier saves you time and money by removing dead email addresses before your next newsletter campaign. Follow these 4 steps to validate your email list automatically:

  1. Load Your Mailing List
    Start by importing your list of email addresses. You can upload huge lists at once or simply test single emails manually. Ensure your computer is connected to the internet before proceeding to the next steps.
  2. Verify Your Port 25 Access
    This is critical: eMail Verifier acts just like a mail server and requires open access to Port 25 to communicate with remote SMTP servers. Before running a large list, verify a single address (other than your own) to ensure your Internet Service Provider (ISP) is not blocking this standard port.
  3. Adjust Your Timeout Settings
    Go to your preferences and check the timeout limit (the default is 5 seconds). If you are testing an older, low-quality list full of dead addresses, you may experience delays. You can adjust this timeout up to 60 seconds if you find some valid servers are just responding too slowly.
  4. Verify and Export
    Click verify to start the multi-threaded engine. The software will extract addresses from the DNS, connect to the SMTP servers, and simulate sending a message (without actually sending one!). Once finished, use the Customizable Export function to save your newly cleaned results.
Pro Tip: eMail Verifier can process over 10 emails per second, but a massive list (e.g., 70,000+ emails) may still take a few hours due to server response times. Simply load your huge lists, hit Verify, and let the software run unattended overnight!

Frequently Asked Questions

No. The software works on the same algorithm as ISP mail systems. It connects with SMTP-servers and simulates the sending of a message to check validity, but it deliberately disconnects the moment the mail server confirms whether the address exists or not. No actual messages are sent to your recipients.

Yes. Because the software needs to directly connect to each address's specific SMTP relay server (MX Exchanger) to verify it, it absolutely requires outbound access to Port 25. Some Internet Service Providers block this port to cut down on spam. If your ISP blocks Port 25, you will need to ask them to unblock it or use an ISP that doesn't restrict it. Alternative ports (like 587) will not work for this specific software.

A timeout simply means the remote mail server is not responding to a command fast enough. If the server doesn't respond within your allotted time (5 seconds by default), eMail Verifier displays a timeout error and moves on to the next address so it doesn't stall your entire list. You can increase this timeout limit in the settings up to 60 seconds if needed.

Yes, Maxprog offers native versions of eMail Verifier for both macOS and Microsoft Windows.

No verification software is 100% perfect, but eMail Verifier uses an advanced set of 80 built-in rules to individually verify each address. It successfully identifies up to 70-80% of all "dead" email addresses, drastically reducing your bounce rate without risking the deletion of valid emails.
