MailChimp & Sprout Forms I am using Sprout Forms for my contact forms and I want to integrate the MailChimp subscribe plugin but it looks like the MC Subscribe plugin needs to have name="mcvars[FIRSTNAME]" on the input fields and Sprout Forms needs name="fields[LASTNAME]".

Also, they have different hidden fields for the action:

MailChimp Subscribe

&lt;input type="hidden" name="action" value="mailchimpSubscribe/list/Subscribe"&gt;


Sprout Forms

&lt;input type="hidden" name="action" value="sproutForms/entries/saveEntry"&gt;


Has anyone managed to integrate the two so people can choose to subscribe to a list while also using the power of Sprout Forms?
Currently, this may be a bit challenging to pull of with Sprout Forms v1.1.0

We do have several features and improvements in the works that will help you achieve this in the future though, including:


Full control over customizing the template HTML
The ability to customize the value of the name="" inputs
The option to submit form data to third-party URLs
Control over hidden fields


While I don't have a release date for you — the features above are currently under development.

I'll plan to revisit and update this post once we release those features.
