The direct approach

What you will need

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

Connect Kartra to AFI

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

Setting up the integration

1. Create a new integration

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

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 Kartra as the destination

Choose Kartra from the platform dropdown and pick Add Lead. This adds a lead to your Kartra account.

4. Map fields

Match each Kartra 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 Kartra 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 Kartra with unlimited records. Pro adds custom field mapping and tag assignment. No per-record fees on any plan.
