Mailchimp

This module provides integration with Mailchimp, a popular email delivery service. The module makes it easy for website users or visitors to control which of your email lists they want to be on (or off), lets you generate and send Mailchimp email campaigns from your site, and lets you and your users view a history of emails they have been sent from Mailchimp. More generally, it aspires to makes your email delivery world efficient and to make your user's email receipt and control simple and precise. Thanks to Mailchimp's ongoing sponsorship, this module is actively maintained and regularly adding features.

Features & Modules The Mailchimp core module provides all of the API integration functionality, and the ability to add your Mailchimp API key and configure a few options. Unless you are writing your own functionality with Mailchimp, it doesn't do much alone. The other features are broken out into the following sub-modules:

Mailchimp Lists

* Directly connect a Mailchimp List to any entity with an email address field or property by adding a field to that entity
* Display subscription forms or status for Lists on entities
* Subscription controlled on Entity creation (including User Registration if desired)
* Map entity fields to your Mailchimp merge fields, including mapping fields on Field Collections and internal values on, for example, Addressfield fields
* Use Views Bulk Operations to create Mailchimp List Segments [D7 only] (Note: This VBO Patch may be needed depending on your versions)

Mailchimp Signup

* Create forms to allow site visitors to sign up for any Mailchimp List or combination of Lists
* Create Pages, Blocks, or both to display forms

Mailchimp Campaign

* Create campaigns containing any Drupal entity, or entities, as content
* Send campaigns created in Drupal through Mailchimp or Drupal interfaces
* View campaign statistics

Installation Notes 2.x
The 2.x release uses composer to install the Mailchimp library. It is also compatible with Ludwig, though composer is recommended. If you are not using one of these package managers to build your site, you will need to install the library manually. (See the README.md)

8.x-1.x
The 8.x-1.x release uses version 3.0 of the Mailchimp API and bundles the library with the module.

7.x-5.x
The 7.x-5.x release uses version 3.0 of the Mailchimp API. A new library is available here and will need to replace the old library if you are upgrading the module from 7.x-3.x or 7.x2.x.

See the README.md for library installation instructions.

Dependencies Make sure your libraries module is version 2.0 or above before you install or upgrade Mailchimp. Drupal will let this module install even if you have 1.0, despite the requirements specification in the Mailchimp module, and the Mailchimp install routine will break.

The mailchimp_campaign and mailchimp_signup modules require the entity module.
