How to Send Email Subscribers Data to ConvertKit

ConvertKit is a email marketing platform for managing subscribers and campaigns. Here is how to pipe Email Subscribers subscriber straight into ConvertKit using Advanced Form Integration. The setup takes about five minutes and runs entirely on your own server.

The direct approach

AFI delivers subscriber data straight from WordPress to ConvertKit. No third-party cloud, no per-task fees, and every request is logged for troubleshooting.

What you will need

• A WordPress site with Email Subscribers installed and configured.
• A ConvertKit account.
• The Advanced Form Integration plugin (free from WordPress.org).

Connect ConvertKit to AFI

1. Log in to your ConvertKit account.
2. Go to Settings → API and copy your API Key and Secret.
3. In WordPress, go to AFI → Settings → ConvertKit.
4. Enter the API Key and Secret, then click Save.

Setting up the integration

1. Create a new integration

Go to AFI → Add New. Name it Email Subscribers to ConvertKit.

2. Pick your trigger

Select Email Subscribers as the form provider. AFI fires when a subscriber joins a list or confirms their subscription, giving you access to subscriber name, email, list ID, and subscription status.

3. Select ConvertKit as the destination

Choose ConvertKit from the platform dropdown and pick Add Subscriber. This adds a subscriber to ConvertKit.

4. Map fields

Match each ConvertKit field on the left to the corresponding Email Subscribers field on the right. Common mappings include subscriber name, email, list ID, and subscription status. You can also use smart tags like {{_submission_date}}.

5. Add conditions if needed

Only want to send certain records? Set up a conditional rule based on any field value.

6. Save and test

Click Save Integration. Trigger a test event in Email Subscribers. Check ConvertKit to confirm the data arrived. If anything looks wrong, open AFI → Log to see the exact request and response.

Free vs Pro

The free version maps email, first name, and last name to ConvertKit with unlimited records. Pro adds custom field mapping and tag assignment. No per-record fees on any plan.
