Checkboxes into Mailchimp from native form

[Meghan_McBain]

Hello. Webflow support has kindly supplied the following instructions:

Here’s how to adjust your Webflow form to send checkbox data to Mailchimp:

Name each checkbox input using Mailchimp’s required format:

• Add checkboxes to your form in the Webflow Designer.
• For each checkbox, click it to access its settings in the right-hand panel.
• In the Name field, enter the exact name required by Mailchimp, such as group[12345][10], where 12345 is the Group ID and 10 is the Option ID.
• Set the Value field to 1 for each checkbox (Mailchimp uses this to register selections).
• Example:
  • Checkbox 1: name="group[12345][10]" value="1"(e.g., “Newsletter”)
  • Checkbox 2: name="group[12345][20]" value="1"(e.g., “Updates”)
• Tip: Find your Group ID and Option IDs in Mailchimp under Audience > Manage Audience > Groups.

A few other things to keep in mind:

• Ensure standard fields like EMAIL, SALUTATION, LNAME, and INDUSTRY are included with their name attributes matching Mailchimp’s merge tags.
• In Webflow, set these names via the element settings panel.

Once you’ve configured your Webflow form as outlined above, the checkbox data should flow into Mailchimp smoothly.

…However, it’s not working. I’m not sure about the value=1, as value isn’t allowed in the custom attribute name field. And I can’t think what else to call it.

I’ve named the form fields as per the code export from the Mailchimp embed form. You can see this in the screenshot here:

And here you can see how I’ve added the value without a label… which I don’t think is right, but unsure what to do.

I’d be so grateful for your thoughts and assistance. I’ve been trying to resolve this issue for several days!

Cheers, Meghan
