Welcome to the eDataSource API

eDataSource's new API allows you to access over 16,000,000 emails from thousands of top marketers.

Start creating applications that empower your customers with the competitive email intelligence they need to increase their ROI and make every email marketing campaign as effective as possible.

Get started today by following these steps:

  1. Register for a user account.  You will be asked to confirm your email address.
  2. Apply for an API key.  With your API key you can begin using the Developer API.
  3. Browse the documentation for guidance on developing your application.
  4. Join a discussion in the forums.
  5. Contact us to discuss your ongoing use of the API.

In order to help you get started we allow limited free use of our Developer API.  Once you know what you want to do with the API we'll need to put an agreement in place so you can develop and deploy your application.
