About the Benchmark Email API
The Benchmark Email API lets you connect your account to external systems such as CRMs, e-commerce platforms, and other applications.
You can automatically add and update contacts, search and manage lists, and sync your data without manual imports. The API also lets you create and manage your own API keys directly in Account Settings > API Keys, with control over access permissions.
API Key Limits
To help keep things secure and manageable, there are limits on how many API keys you can create:
- Free plans can create up to 2 API keys
- Pro plans can create up to 10 API keys
If you reach your limit, you’ll need to deactivate an existing API key to create a new one.
