Installation Guide

Please note that we highly recommend composer installation.

Composer installation:
    1. Look for the latest version required for your Magento instance at Mailchimp for Magento 2 releases and run the command listed in it.
    2. Run from command line: bin/magento setup:upgrade
    3. Run from command line: bin/magento setup:di:compile

About the library installation:

The mailchimp-lib is a required dependency of the Mailchimp module, when you install Mailchimp for the first time via composer, the library is also automatically installed as well, but when you are updating Mailchimp via composer the latest version of the library isn't always downloaded automatically and it can cause issues, it can be updated manually at any moment running the following command:

composer require ebizmarts/mailchimp-lib

You can make sure to you are getting the latest version here:

When installing the Mailchimp extension using the Manual method (in app/code - NOT RECOMMENDED), the library must be installed via composer separately always anyway, if you try to install it manually it will simply not work.

Mailchimp for Magento 2 is available at Ebizmarts' StoreMakento Marketplace and GitHub.
