Add new Fourthwall newsletter subscribers to a Mailchimp audience

When a fan subscribes to the newsletter on your Fourthwall site, this workflow adds their email address to the Mailchimp audience you choose, so your campaign list grows without CSV exports.

What this workflow does

Fourthwall lets fans sign up for your newsletter on your creator shop, but the campaigns you send probably go out from Mailchimp. Moving those sign-ups across by export and import is slow, and fans who join between exports miss your next email. This workflow moves each one as it happens.

The Fourthwall trigger fires on Newsletter Subscribed, when someone subscribes to your newsletter there. FlowMattic takes the subscriber data Fourthwall sends and passes it to Mailchimp with the Add New Member action. That action adds the person to your audience, or updates them if the address is already a member.

Because existing members are updated, a fan who is already on your list keeps a single member record that takes the values you map. Run a test sign-up after import so you can map the email field and any name details Fourthwall includes.

After importing, map your own data. To keep the template universal, not every step is pre-filled. Open each step in the builder and connect your accounts and fields (channels, lists, sheets, recipients) before you switch the workflow on.

Make it yours

Changes worth making after you import it.

Add a Filter between the Fourthwall trigger and the Mailchimp step that continues only when the email field is not empty, so the Mailchimp step only runs for sign-ups that carry an address.
Build a copy of this workflow with Fourthwall's Order Placed trigger feeding the same Add New Member step, if you also want buyers in that Mailchimp audience.
Sign up with a test address after import and check Task History to see the fields Fourthwall sends before you finish the Mailchimp mapping.

Questions about this workflow

What if the Fourthwall subscriber is already in my Mailchimp audience?

Add New Member adds new people and updates people who already exist, so that fan's existing member record is updated with the Fourthwall values you map. Task History shows what Mailchimp returned.

Are my existing Fourthwall subscribers copied to Mailchimp?

No. The trigger fires on new sign-ups after the workflow is turned on, so people who subscribed earlier have to be moved to Mailchimp separately.

Which Mailchimp audience do Fourthwall fans join?

The audience you select in the Add New Member step after connecting your Mailchimp account. Every new Fourthwall subscriber goes to that one audience.
