Connect Contact Form 7 to MailerLite

Connect Contact Form 7 to MailerLite and every form submission becomes a subscriber in the group you choose. The free ClickSyncr for MailerLite plugin adds its own tab to the Contact Form 7 editor: paste an API key, pick a group, map your fields, save. No code and about two minutes per form.

Before you begin

You need three things: the ClickSyncr for MailerLite plugin activated, Contact Form 7 active, and a MailerLite account (the free tier is fine, with permission to create an API token). Contact Form 7 stores the API key per form, right inside the form editor.

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.

Contact Form 7 setup, step by step

1. Open your form and switch to the ClickSyncr MailerLite tab. From Contact → Contact Forms, open a form. The plugin adds its own tab next to Form, Mail, Messages and Additional Settings. You can also jump straight there with /wp-admin/admin.php?page=wpcf7&post=YOUR_FORM_ID&active-tab=clicksyncr-ml-panel.
   

   

2. Paste your API key and connect. Also, the connect button turns green and reads Synced once the key is verified. The eye icon reveals the key if you need to check it.
   

   

3. Choose the MailerLite group. In fact, the dropdown fills with every group in your account and shows each one’s subscriber count. Use Refresh Groups after creating a group in MailerLite.
   

   

4. Map your form fields. Then each MailerLite field gets a dropdown listing your form’s tags. Email is required; if you map nothing else, map that.
   

   

5. Optional: set a consent field. Also, choose a checkbox, acceptance or radio field to drive opt-in. Ticked adds the subscriber as Active; unticked adds them as Unconfirmed. Leave it on None to add everyone as Active.
   

   

6. Save the form. In addition, the next submission syncs.

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

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

Troubleshooting

Does each Contact Form 7 form need its own key?

Each form stores its own key and mapping, so different forms can even feed different MailerLite accounts. Most sites paste the same key into each form.

Can Contact Form 7 add subscribers with opt-in consent?

Yes. Point the consent control at an acceptance or checkbox field and only ticked submissions arrive as Active subscribers; unticked ones are stored in MailerLite as Unconfirmed.

Frequently asked questions

Does unchecked consent send an Unconfirmed subscriber to MailerLite?

An unchecked configured consent field currently prevents the Contact Form 7 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 Contact Form 7 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 Contact Form 7 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.
