Connect Forminator to MailerLite

Connect Forminator to MailerLite and every form submission becomes a subscriber in the group you choose. The free ClickSyncr for MailerLite plugin registers a native Forminator application: connect it once, activate it on any form, map your fields, publish. No code and about two minutes per form.

Before you begin

You need three things: the ClickSyncr for MailerLite plugin activated, the free Forminator plugin active, and a MailerLite account (the free tier is fine, with permission to create an API token). You connect once for the whole site.

Get your MailerLite API key

1. Log in to MailerLite and go to Integrations → API (dashboard.mailerlite.com/integrations/api).
2. Generate a new token and give it a recognisable name such as WordPress ClickSyncr.
3. Copy it immediately: MailerLite shows the full token only once. If you lose it, generate another.

Treat the token like a password. Anyone holding it can read and modify your MailerLite subscribers.

Forminator setup, step by step

1. Connect MailerLite (ClickSyncr) globally. Go to Forminator → Integrations, find MailerLite (ClickSyncr) and connect it with your API key. Once connected it appears under Connected Apps.
   

   

2. Activate it on your form. Also, open your form in the wizard and switch to the Integrations tab. Activate MailerLite (ClickSyncr), then walk through the short setup: pick the group, set the email field, and map the rest.
   

   

3. Publish the changes. In fact, click Publish Changes so the activation is live. Submissions now sync to the group you picked.

The nine MailerLite fields

Every builder maps the same nine standard MailerLite fields, and any custom fields in your account appear in the list automatically. Only Email is mandatory; an unmapped field is simply skipped and never overwrites existing subscriber data with a blank value. If MailerLite rejects one value’s type, that single field is dropped and the subscriber still syncs.

Verify the sync

First, submit the form on the front end (not the admin preview) with a test address you can recognise, filling every mapped field. Then, in MailerLite, open Subscribers and confirm the subscriber exists, sits in the group you selected, and carries the mapped values. In short, that one minute catches almost every configuration mistake.

Troubleshooting

Does this work with the free Forminator?

Yes. The MailerLite (ClickSyncr) application registers in the free Forminator plugin from WPMU DEV; no pro tier is required.

Can I apply the integration to only some forms?

Yes. Forminator applies integrations per form, so only the forms you activate it on will sync, each with its own group and mapping.

Frequently asked questions

Does unchecked consent send an Unconfirmed subscriber to MailerLite?

An unchecked configured consent field currently prevents the Forminator submission from being sent to MailerLite. That differs from selecting Unconfirmed as the saved subscriber status when no consent field is used. Check both controls before testing: the consent answer takes priority. A recorded “Nothing was sent. Consent was not given.” result means there was no subscriber request for that submission.

What does the MailerLite rate-limiting error mean?

The message “MailerLite is rate limiting this account. Try again shortly.” means MailerLite refused the request because of its request limit. It is a delivery error, not evidence that the Forminator field mapping is wrong. Avoid repeatedly submitting the form while investigating. Check the contact and the recorded result, allow the account limit to clear, and then run a controlled test.

Which types can a new MailerLite custom field use?

The plugin’s field-creation method accepts text, number, or date. A field also needs a nonempty name; choosing another type is rejected before the creation request is sent. Decide what the Forminator answer represents before creating its destination field. A numeric answer belongs in a number field, while descriptive content needs text. After creating the field, check the mapping and submit a representative value.
