How are email addresses checked?
We check each and every email at 3 levels:
- Syntax – Is the address in the right format? (e.g. email@example.com)
- MX – Does a mail server exist for a domain?
- Mailbox – Our server talks to remote mail server and asks “Does this mail box exist?”
How accurate is this service?
Very. For various technical reasons, it is the most accurate service that you can find anywhere and we aim for between 97-99% overall accuracy based on a typical email list.
We are so confident of our claims that we back them up with a full satisfaction money back guarantee*. Find a more accurate email address checker and we’ll give you your monthly subscription fee back with no questions asked*.
How does your service handle 'Grey Listing'?
Please use our bulk email address checking service for automated grey listing management.
Our real time validation service (tools.email-checker.com) flags grey listed addresses for you to manually re-check at a future time.
Does your service detect spam trap emails?
We don’t tag spam trap emails as they are a constantly moving target. Any spam trap database is instantly out of date the moment it’s published as new spam trap emails are probably created every second of every day.
We looked at providing this feature but felt that we couldn’t do it accurately enough to back it up with a “stated accuracy” figure as we do with overall accuracy. Interestingly, we’ve never had a complaint (in the years of running our other checking services) about inaccuracy from detecting spam trap emails.
In our product design, we focused more on core accuracy (which we beat PC based checkers on by a substantial margin). Maybe we’ll re-visit spam tram addresses in a future release.

Why should I pay for this service?
Our email checking services are the best out there. Every day we check thousands of emails on behalf of thousands of satisfied users.
Top quality services such as our don't happen by accident. We invest financially in server hardware, bandwidth, staff, development, testing and a multitude of other areas in order to provide you, our users, with robust and high quality services.
Like any quality service, we charge a fee.
If you use and enjoy this service, please subscribe and support us in continuing to provide you with the best email checking tools available.
We are aware that there are other free services out there that you could use. Here are some reasons why our customers choose our service over the free alternatives:
- Robust service - with 99.9% uptime.
- No advertising - can be annoying on free sites.
- Best possible accuracy - email address checking is not an exact science due to the nature of email servers. A few email addresses just can't be checked. Most free services get around the problem by telling you that an address is valid when they don't know (e.g. punch any Yahoo address into a free checker and it will always say "valid"). We differentiate addresses that we know can't be checked from those that are genuinely valid / not valid.
- Advanced features - such as grey listing detection, email extraction and supplemental search info. Free services don't provide these.
We respect your choice of "free" (or advertising subsidised) versus subscription. However, as a paid service, we are better motivated to provide robust, accurate and feature rich services than those of our "free" competitors.
Ultimately your decision is cost versus quality. If you use our services for business purposes where each of your email leads can cost or make you dollars, are you happy with lower quality results from free services?
