Mapping form custom fields to MailChimp custom fields
When adding custom fields to ConvertFlow form elements, you can choose to select from "MailChimp fields". This allows you to map contact info entered into the ConvertFlow custom field, into the correct subscriber custom field in MailChimp.
Mapping survey fields to MailChimp custom fields
When you create a survey element in ConvertFlow, click on the "Map to custom field" dropdown to the right in the builder panel, and you can select from your MailChimp custom fields
Mapping preset ConvertFlow fields to MailChimp custom fields
On your website's Integrations page, when you have MailChimp connected, you'll see a "Fields" button, that when clicked, allows you to map ConvertFlow's preset contact fields to MailChimp custom fields.
This is useful for mapping contact info added to ConvertFlow's preset fields through ConvertFlow's forms, that isn't already mapped to fixed fields in MailChimp. For example, "first name" and "email address" are already mapped to MailChimp for you.
Just enter the data name of the MailChimp custom field you would like ConvertFlow's preset fields to be mapped to, and you're set!
