These Direct Mail API Usage Guidelines (these “Guidelines”) provide additional terms with respect to your access to and use of any APIs provided by Postalytics, Inc. (“Postalytics”).

The APIs are powered by the same underlying technology that powers the core Postalytics application. As a result, Postalytics closely monitors usage of the APIs to ensure a quality experience for users of the Postalytics platform.

Postalytics has the following limits in place for API requests:

  1. 15 requests per second
  2. 900 requests per minute.

Rate limits are based on and throttled by IP address as well as API key. Customers exceeding either of those limits will receive error responses with a 429 response code.

Integrations (as identified by an access token) that poll Postalytics for new or updated information are limited to polling for those changes at intervals of 5 minutes or more.

Requests resulting in an error response may not exceed 5% of your total requests.

Integrators should use their own public and documented APIs when working with the Postalytics Direct Mail API.

Abuse or excessively frequent requests to Postalytics platform via the API may result in the temporary or permanent suspension of your account’s access to the API. Postalytics, in its sole discretion, will determine abuse or excessive usage of the API. Postalytics will make a reasonable attempt via email to warn the account owner prior to suspension, provided we may throttle your sending or connection through our API at our discretion.

Postalytics reserves the right to change or deprecate the APIs over time. Postalytics may also update and change any part or all of these Guidelines. The updated Guidelines will become effective and binding on the next business day after it is posted. When we change these Guidelines, the “Last Modified” date above will be updated to reflect the date of the most recent version. We encourage you to review these Guidelines periodically.
