MailChimp integration for Plone 4 and 5.

MailChimp helps you design email newsletters, share them on social networks, integrate with services you already use, and track your results.

collective.mailchimp provides a @newsletter view to let visitors subscribe to one or more MailChimp mailing lists. It also provides a MailChimp portlet in case you want to display your newsletter subscription as part of an existing site.

The newsletter subscriptions forms in both the view and the portlet are extendable, so you can add custom fields that can be stored in your MailChimp subscriber list.

It also comes with a MailChimp control panel to let you enter your MailChimp credentials for your Plone site.

collective.mailchimp is tested on Plone 4.x and 5.x and should work on Plone > 3.3 (with the appropriate version pins for and z3c.form).


Install collective.mailchimp by adding it to your buildout:



eggs =

and then running "bin/buildout".

Multiple MailChimp Lists

collective.mailchimp supports multiple MailChimp lists. The MailChimp portlet allows administators to choose a MailChimp list from a dropdown list for each portlet. The MailChimp newsletter view (@@newsletter) allows to provide a list_id (see your MailChimp account) as optional URL parameter:


If no URL parameter is provided the form just chooses the first MailChimp list available (which is fine as long as you have just one list anyway).

Preselect Interest Groups

collective.mailchimp supports MailChimp's interest groups. In case there is more than one single group you might want to pre-select some of the groups. To do so add one or more 'preselect_group' parameters to the URL that points to your MailChimp newsletter form. For instance to select the first and the fifth group entry use the following link:


Note: if you used version 1.4.1 of collective.mailchimp or earlier, you may no longer see the interest groups on the subscribe form. You should visit the control panel again. This will update the data automatically.

Extend Newsletter Subscription Form

The collective.mailchimp newsletter form (used in the separate view as well as in the portlet) can be extended without touching the code of collective.mailchimp.


collective.mailchimp has been written from the scratch in order to replace raptus.mailchimp for newer versions of Plone (> 4.0).

The difference between collective.mailchimp and raptus.mailchimp is:

  • Directly use the MailChimp API instead of greatape as Python wrapper (because greatape is completely untested, does not support the latest MailChimp API version and seems to be not actively developed any longer)
  • z3c.form instead of formlib for forms (because formlib is deprecated)
  • instead of portal_properties for storing properties (because portal_properties will be deprecated soon)
  • it is tested by automated software tests (because untested code is broken code)
