What this workflow does
Formidable Forms is often the form behind a newsletter box, a quote request or a download gate. The entries sit in WordPress, while your emails go out from MailerLite. This workflow moves each new person across as soon as they submit.
The Formidable Forms trigger runs when a form is submitted on your site. FlowMattic passes the submitted fields to MailerLite, where Create or Update Subscriber adds the person. If the email is already a subscriber, MailerLite updates that record with the new details instead of adding a second one.
You map the form's email field and any name or custom fields after import. Formidable keeps its own copy of the entry as usual, so nothing changes on the WordPress side. Only entries made after you turn the workflow on are sent.
Newsletter sign-up in a sidebar
A short Formidable form in your blog sidebar collects name and email, and each new reader becomes a MailerLite subscriber you can send your next issue to.
Quote requests from a services page
A builder's quote form passes each enquirer to MailerLite, where a custom field holds the service they asked about.
Gated downloads
Visitors fill in a Formidable form to get a checklist. They join MailerLite at the same moment, ready for the follow-up emails you write there.
How this workflow runs
What happens at each step once the workflow is on, and what you need before you import it.
Formidable Forms New Form SubmissionRuns each time a visitor submits the Formidable Forms form you pick. Every field from the entry is available to map into MailerLite.
MailerLite Create or Update SubscriberCreates the person in MailerLite, or updates the subscriber who already has that email. Map the email, name and any custom fields, and connect MailerLite.
What you need
- FlowMatticCore
- Formidable Forms PluginPlugin
- MailerLite AccountAccount
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 MailerLite's Add Subscriber to a Group as a third step so each person joins the group that matches the form they filled in.
- Add a Filter after the trigger on your consent checkbox so only people who agreed to receive emails reach MailerLite.
- Submit one test entry after import so FlowMattic captures the form's fields, then finish the mapping before you turn the workflow on.
Questions about this workflow
What happens if the Formidable Forms submitter is already a MailerLite subscriber?
Create or Update Subscriber updates the existing subscriber with the same email, so they are not added twice.
Does editing a Formidable entry update MailerLite?
No. This template uses New Form Submission. Formidable also has a Form Submission Updated trigger in FlowMattic if you want edits sent in a second workflow.
Are older Formidable Forms entries sent to MailerLite?
No. Entries from before you switch the workflow on never start a run. Export older entries and import them into MailerLite once if you need them.
Can Formidable fields fill MailerLite custom fields?
Yes. Map each form field to the MailerLite custom field that should hold it, as long as that field exists in your MailerLite account.
