How to Subscribe a Contact Form 7 Visitor to ConvertKit

A lead who fills in your enquiry form is ready to hear from you. Zapify subscribes them to a ConvertKit form, and so into its sequence, with the free A form is submitted trigger and the Subscribe to a form action. ConvertKit is a Zapify PRO integration.

What this automation does

The automation is one trigger plus one action:

• Trigger: A form is submitted (CF7_FORM_SUBMITTED, Contact Form 7)
• Action: Subscribe to a form (CONVERTKIT_SUBSCRIBE, ConvertKit)

Each time the form is submitted, Zapify subscribes the visitor to the ConvertKit form you choose.

Before you start

• Contact Form 7 installed and active, with a published form that has an email field.
• A ConvertKit API key — from your ConvertKit account settings. See ConvertKit's developer docs if you can't find it. The API secret is not needed for this action.
• The Form ID of the ConvertKit form to subscribe people to — the number at the end of the form's URL in ConvertKit.

How to build the automation

Step 1: Connect ConvertKit

1. Go to Settings → Connections and click Add New.

2. Choose ConvertKit, paste in your API key, and name the connection something like Course ConvertKit.

3. Save. The API secret field can be left blank — it's only needed for actions that read or delete data, not for subscribing.

See Connections for how this screen works generally.

Step 2: Create a new automation

1. In the WordPress admin, go to Zapify → Automations.
2. Click Add New to open the builder.
3. Name it clearly, such as Subscribe enquiries to ConvertKit.

Step 3: Add the "A form is submitted" trigger

1. Click Add Trigger.

2. Choose Contact Form 7 as the app.

3. Select A form is submitted.

4. In the Form field, pick the specific form. Choosing a form gives you one token per field on it.

Step 4: Add the "Subscribe to a form" action

1. Click Add Action.

2. Choose ConvertKit as the app.

3. Select Subscribe to a form.

Step 5: Configure the action

Field	Required	What it does
Connection	Yes	The ConvertKit connection you set up in Step 1.
Form ID	Yes	The number at the end of the form's URL in ConvertKit.
Email address	Yes	Insert the token for the form's email field.
First name	No	Insert the form's name token.
Tag IDs	No	Comma-separated. ConvertKit tags are numbers, not names — find a tag's ID in ConvertKit's own interface.

Step 6: Set the steps Live and save

Each trigger and action has its own Live / Off / Draft switch. A new automation starts as a Draft and does nothing until its steps are Live.

1. Set the trigger and every action to Live.
2. Click Save.

Step 7: Test it

Submit the form with an address you control. Check the subscriber in ConvertKit, or open Zapify → Logs.

Tokens you can use

Once you select a specific Contact Form 7 form, the trigger exposes these tokens. Insert them anywhere in the email with the {} button.

Token	What it holds
Form ID	The numeric ID of the submitted form.
Form title	The form's name.
Submitted at	The date and time of the submission.
All fields	Every submitted field rendered as one labelled block — handy when you just want the whole submission in the email.
One token per field	The value the visitor entered in that field, named after the field's tag (for example a your-email tag becomes a your-email token).

Multi-value fields such as checkbox groups are joined into a readable, comma-separated list.

Conclusion

With the free A form is submitted trigger and the Subscribe to a form action, every enquiry joins your ConvertKit sequence. For buyers instead, see subscribing a customer to ConvertKit when a product is purchased.

FAQs

Is this free in Zapify?

The trigger is free. The ConvertKit action needs an active Zapify PRO licence and a Connection.

Do enquirers consent to marketing emails?

An enquiry is not always consent. Add a consent checkbox to the form and only continue when it is ticked. See Filters and conditions.

Do I need to write any code?

No. Everything is set up visually.
