It seems that if add the action and POST URL to connect that form to my mailchimp audience, then the form that was just submitted will only send the data to mailchimp - and not send the form to the specified email in Webflow’s native form capabilities.
Is this true, and if so is there a workaround?
Correct, when you set the action, you’re supplying your own form submission handler to replace Webflow’s.
If you really wanted Webflow’s handler to run as well - usually not the case with newsletter enrollments - then you could build an automation against Webflow’s form submission webhook, and add the new subscriber through Mailchimp’s API.
Essentially, the goal is to have people submit their inquiry and simultaneously having the option to opt into our newsletter marketing, whether it be a checkbox or a disclaimer.
If the Mailchimp API is the only solution, do you have any resources on completing this that I can follow along with?
Google will be your best way to find Webflow + Mailchimp integration resources. But you have a ton of setup options here.
The easiest one is to just build your form normally then use an automation platform like Make.com to trigger on new form submissions. There, check your opt-in, and add the user’s email to Mailchimp if they requested the newsletter.
Thanks for the proposed solution. Is the part where adding the user’s email to Mailchimp if they requested the newsletter an automated feature of Make.com?
Make is an automation platform, you just set up the automations the way you want. It natively supports Webflow and Mailchimp modules, so it’s relatively easy to learn the setup.
