When a new user is added to WordPress, add a new member to Mailchimp list

When a user account is created on your WordPress site, this workflow adds that person to the Mailchimp audience you choose, or updates them if they are already a member, so your list keeps pace with site sign-ups.

What this workflow does

Your site's user list and your Mailchimp audience drift apart unless someone syncs them. People register, never get your newsletter, and the CSV export you meant to run each month gets skipped. This workflow copies each new WordPress user into Mailchimp the moment the account exists.

The WordPress trigger, New User, runs when a user is registered on the site where FlowMattic is installed. It hooks into WordPress user creation, so accounts made through the registration page, a membership or shop plugin, or the admin screen all count. The user's details and stored meta pass to Mailchimp, where Add New Member puts the email on your list, or updates the existing member if the address is already there.

As imported there is no Filter, so every new account is sent. Check that people agreed to marketing email before you add them, and use the tips below to narrow who gets through. Task History shows each run and Mailchimp's reply.

Online course students

Students create a WordPress account to access lessons. Each one joins the Mailchimp audience you use for course announcements and new-module emails.

Customers who register at checkout

A WordPress shop creates an account for buyers who choose to register. They are added to Mailchimp, so your product updates reach account holders.

Members of a private community

New members of a members-only site land in Mailchimp, where you send the monthly community round-up.

How this workflow runs

What happens at each step once the workflow is on, and what you need before you import it.

Step 1Trigger
WordPress New User
Fires whenever WordPress creates a new user account on this site. The user's email, login name and stored user meta become available to map into Mailchimp.
Step 2Action
Mailchimp Add New Member
Adds the new user to the Mailchimp list you choose, or updates the member if that email is already on it. Connect your Mailchimp account and map the WordPress email, plus any name values you want.

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 after the trigger on the user's role, found in the user meta, so administrator and editor accounts never reach your Mailchimp audience.
Use a Router with one route per user role, each with its own Mailchimp step, when customers and members belong in different audiences.
Create a test user from the WordPress admin screen after import, then confirm the member appears in Mailchimp before you turn the workflow on for real sign-ups.
