How do checkboxes work in Mailchimp?

In the Mailchimp hosted forms tool, there is a checkbox (multiselect) that you can add to your form. However, that field type is only available to allow members to manage their Mailchimp Groups. It can't be used like their other Merge Fields, to merge data into emails or to define segments. You can read more about Mailchimp field types in their documentation.

Therefore, integrating Salesforce checkboxes with Mailchimp varies depending on the direction of data flow.

Salesforce to Mailchimp

We recommend mapping the Salesforce checkbox to either a Mailchimp text, radio button or drop down to handle this. Here are the options:

• Text Field: This is the simplest method. When you push data from Salesforce to Mailchimp, the text field will store the value as “true” or “false” without restrictions. If you add the new Merge field from within our app, we create a text field. 

• Drop Down or Radio Buttons: You can also map your checkbox to these field types in Mailchimp, with the values 'true' and 'false' (lower case).
 

Note: To map a Salesforce checkbox to any value other than the true/false picklist we can support in Mailchimp, you will need to create a separate formula field in salesforce. This formula should translate the checkbox to your Mailchimp picklist values (Yes, No, etc). Map this formula field to Mailchimp instead of the checkbox. You will only be able to map this formula field via the Data Wizard, not via Mappings, since formulas can't trigger mappings.

Mailchimp to Salesforce

In this direction, you can use a picklist or radio button field in Mailchimp with two choices.

The integration supports the following option values in that Mailchimp field when mapping to a Salesforce checkbox:

• Yes or No

• 1 or 0

• True or False

These values are not case-sensitive, ensuring flexibility and ease of integration.
