Our Activity Data feature allows you to gather insights into your subscribers’ overall email engagement. The tool returns if the email inbox has been active in the past 30, 60, 90, 180, 365, 730 or 1095 days. Thus, you can improve your targeting and personalization, and run more successful email campaigns.

If you’re interested in returning results via an API, Activity Data is also compatible. The API endpoint URL is below, please replace your_api_key with your API key from your account.

If you are not sure where to find your API key, you can generate one, or use an existing key. If you’re uncertain on how to interact with our API, please refer to our expanded API documentation.

As with dashboard usage, the API endpoint will consume a credit only when a positive match has been found. If the response is found: false, the Activity Data API will not consume any of your credits.

Using Activity Data via the API provides results in real time and enables you to add this additional information to your email list instantly. If you need guidance on using the API, please don’t hesitate to get in touch with our 24/7 customer support team.
