Introduction to the Moosend API

Abstract

Introduction to the Moosend API and what topics are included in this API documentation.

Moosend is a cloud-based, AI-powered email marketing solution that allows you to target your audience at scale.

The API enables you to connect directly to the Moosend infrastructure and programmatically run many of the system’s capabilities from creating email lists to retrieving advanced real-time analytics in an easier, faster, and more efficient manner.

To get started, you need a Moosend  account and an API key. By accessing the API endpoints, you can programmatically leverage the system’s core capabilities:

Email lists

  • Create, retrieve, update, or delete email lists and their details.

  • Create or update custom data included in the email lists.

Subscribers

  • Add up to 1000 subscribers with their custom data or retrieve them by ID or email address.

  • Remove subscribers or unsubscribe them from an email list or a campaign.

Campaigns

  • Create or clone campaigns, and efficiently retrieve their details and campaign senders.

  • Send a test campaign, schedule campaign delivery, or dispatch it immediately.

  • Retrieve campaign metrics such as link performance, opens, clicks, and A/B test results to make data-driven decisions.

Segments

  • Create, update, delete, and retrieve segments with their details and subscribers.
