We’ve been validating email addresses since 2004. Email address checking started originally on our “niche” site Broadband-help.com and then moved to our corporate site Rolosoft.com in 2007.

Our free email address checker is one of the most popular email validators on The Internet. Every day, we check and validate thousands of email addresses through our free checker.

Since 2007, we have provided commercial API web services using XML and SOAP standards. Today, we support a number of medium to large clients across the globe with this service and we check tens of thousands of email addresses on their behalf every day.

Over the years of running email address checking services, we have developed a detailed knowledge of what it takes to deliver accurate email address checks in near real-time. We have learnt that it simply is just not possible to provide a satisfactory email address checking service that is anything other than server based. That’s to say that we know (and you should too!) that software that you download and install onto your computer simply cannot deliver accurate email address checking.

We have created our bulk email checking service (Email Address Checker) to complement our existing services. Email Address Checker has been engineered to deliver robust, accurate and affordable email address checking capabilities to our customers in a way that has never been done before by anyone else.
