Connect Ninja Forms and Mailchimp
Ninja Forms collects enquiries, sign-ups and requests on your WordPress site, and FlowMattic runs right beside it. Each submission can add or update a Mailchimp member, with tags from dropdowns and notes from the message box. It suits small businesses, nonprofits and agencies whose contact and newsletter forms are built in Ninja Forms.

Ninja Forms and Mailchimp workflows you can build
Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.
Ready-made template Tag members with the service they asked about
A dropdown such as Which service do you need becomes a tag, so the email about web design only goes to people who picked web design.

Keep the enquiry message on the member profile
Add Member Note saves what the person wrote in the message box, so whoever follows up from Mailchimp can see the question without searching the inbox.

Update details for people already on the list
Find Member checks the email. A Router runs Update Member for someone already on the list and Add New Member for someone new, so their details stay current.

Handle unsubscribe requests from a site form
Some people ask by form instead of the email link. Find Member locates them and Archive Member takes them off your sends while keeping their history.

Send each form's sign-ups to its own audience
A Lookup Table maps the form title to an audience, so one workflow serves your shop newsletter form and your volunteer form without mixing the lists.

Set up: entries as Mailchimp members
At the end, each submission of your Ninja Forms form adds the person to one Mailchimp audience.
Connect Mailchimp

Triggers and actions in this pair
A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Good to know
- These workflows go from a Ninja Forms submission to Mailchimp. Mailchimp triggers can start other workflows, not change a form entry.
- Contact forms get repeat visitors. Check with Find Member first and send people already in the audience to Update Member.
- Field names come from your own form, so the mapping is an example. Remap after editing the form.

Why run this pair with FlowMattic
Ninja Forms and Mailchimp connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Form and workflow on one site
Ninja Forms and FlowMattic both run in your WordPress, so entries go to Mailchimp from your own server.
Every form, no task count
Runs are unlimited, so every contact, newsletter and event form can feed Mailchimp on the same plan.
More than a list sign-up
Tags, notes and archive steps carry what the person asked for, not just their email address.
Common questions
How do I connect Ninja Forms to Mailchimp?
Create a FlowMattic workflow with the Ninja Forms New Form Submission trigger, add Mailchimp Add New Member, choose the audience and map the email and name fields.
Can a checkbox decide whether someone is added?
Yes. Add a Filter after the trigger that continues only when the newsletter checkbox is ticked, so contact enquiries without consent are not subscribed.
Can one form feed different audiences?
Yes. Use a Router on a field such as location or interest, with an Add New Member step per audience on each path.
Do I need the Ninja Forms Mailchimp add-on?
No. FlowMattic reads the submission directly and talks to Mailchimp through your connection under Connects.
