BulkEmailVerifier.com is a SaaS service, which means there is no software to install - delivered online by us. We run the checks from our own servers, so there is no risk of "blacklisting" your own IP address like competitor software. Give it a try here and see how it works :

Batch or Real-time Verification

Our service can be used to upload bulk lists of email addresses, or as a web service for real-time checking.

A Simple Process For You!

We have done all of the hard work for you. All you have to do is upload your email list and wait for the results to process. We support batch files in CSV or TXT formats to give you flexibility.

So What Do We Check?

Actually, we do the complete email verification run, which includes :

• Syntax - a simple check to ensure the email address conforms to RFC standards.
• Domain - a lookup on the domain element of the email address to ensure it is configured to accept emails.
• Mailbox User - the in-depth part, where we check that the user really mailbox exists or not.
• We never send an email during our checks.

Years Of Expertise

With well over 2 years of development time contributed into our application, we assure you that we can deliver the most reliable email verification anywhere. It is our focused specialty, and we have gotten really good at it. We have built BulkEmailVerifier.com to cope with the many variates of mail servers from services, including grey-listing, false positives and velocity blocks. What we do is an unmatched science, by performing reliable email checking at the volumes we deliver is a very challenging task requiring detailed knowledge of how Internet Service Providers work, and the mail server technology behind the emails themselves. No other email verification service can match the accuracy of our checks, we've already looked into it.

Lightning Fast Verification

We can verify emails at rates well over 100,000 emails per hour thanks to our beefy infrastructure.

Reliable and Secure

Security of your data is our primary concern. To ensure security, we implement:

• Robust data security implemented using Microsoft Trustworthy Computing guidelines.
• Logical security of your data by allocation of your own, dedicated database. Any data that you upload goes into your database and is not visible by anyone else for any reason. Your own secure spot in our cloud, with no data sharing.
• Physical security in our US and EU data centers, servers, and backup devices. Lock and keyed, with ID scan.
• Once you delete a list from our system, it is wiped completely off our servers. We have no interest to retain.

Ultimately, no one gets access to your data except you. As well as the assurance of security, we appreciate that you want reliability. That’s why, as a customer, you receive priority support by phone and email. In the unlikely event of a technical problem, our promise to you is to resolve your issue within 24 hours. Our systems include built in exception and error alerting to give us a proactive glimpse of what is going on. Meaning that, in the unlikely event that you need to call us, we will usually already know about the problem and already be working on a fix for it!
