CheckMail – Email Address Verification

It’s been a few weeks since I launched a new service I’m involved in, and so far the take-up rate has been extremely encouraging.

CheckMail is an email address verification service. Put simply, you give us an email address, and we’ll tell you if it’s a valid, working, email address or not. You can bulk-validate a CSV or Excel file with your email addresses, or you can integrate our solution into your lead generation process using our API.

So far we’ve had a great take-up rate using our API, which is our primary focus for the CheckMail service. Customers can get up and running quickly with the CheckMail API libraries for Node.js, PHP, Python, and Ruby.

We maintain multiple geographically load balanced instances of the CheckMail API, in six different locations throughout the world, to ensure the fastest response times possible for all our customers.
