Subscribe contacts to Mailchimp from a web form
A public form that adds the contact to your Mailchimp audience, with email confirmation and a source tag.
Everything is created inactive in a new folder of your account. Nothing runs until you activate it, and you can undo it for 24 hours.
What it does
Capture subscribers without touching Mailchimp. The person fills in the form (first name, last name, email and consent) and the flow adds them to your audience through the Mailchimp API, with a tag showing where they came from.
By default it uses double opt-in: Mailchimp sends an email to confirm the subscription, which is recommended for GDPR. If the contact already existed, their data and tags are updated without duplicating them. If someone who unsubscribed tries to subscribe again from here, Mailchimp does not allow it and the form explains why.
What you need: a Mailchimp account, an API key and the audience ID (steps below).
