Connect Gravity Forms to MailerLite

Connect Gravity Forms to MailerLite and every form submission becomes a subscriber in the group you choose. The free ClickSyncr for MailerLite plugin adds a native Gravity Forms feed: connect your API key once, add a MailerLite feed to any form, map your fields, save. So there is no code, and it takes about two minutes per form.

Before you begin

You need three things: the ClickSyncr for MailerLite plugin activated, Gravity Forms active (any license tier), and a MailerLite account (the free tier is fine, with permission to create an API token). Gravity Forms uses the shared plugin key: paste it once under Forms → Settings → MailerLite and every builder on the site reuses it.

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.

Gravity Forms setup, step by step

1. Connect your API key once. Go to Forms → Settings → MailerLite and paste your key. This is the same shared key used by the other builders: saving it here fills it everywhere, and the other way round.
2. Open the MailerLite feed screen for your form. Also, go to Forms, open a form, then Settings → MailerLite and click Add New. Feeds are per form, so each form can have its own group and mapping.
   

   

3. Fill in the feed and save. In fact, name the feed, pick the MailerLite group, map Email (required) and the rest of the nine fields, then choose the subscriber status and an optional consent field. Click Save Settings.
   

   

4. Done. In addition, every submission that passes the feed now syncs to MailerLite.

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

Is this a Gravity Forms feed add-on?

Yes. ClickSyncr for MailerLite registers a standard Gravity Forms feed add-on, so feeds behave exactly like the Gravity Forms integrations you already know, including conditional logic from the feed framework.

Do I need a specific Gravity Forms license?

Any license tier works. The plugin only needs Gravity Forms itself active on the site.

Frequently asked questions

Does unchecked consent send an Unconfirmed subscriber to MailerLite?

An unchecked configured consent field currently prevents the Gravity Forms 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 Gravity Forms 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 Gravity Forms 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.
