Smartlead is a cold email outreach platform for managing subscribers and campaigns. Here is how to pipe Ninja Forms submissions straight into Smartlead using Advanced Form Integration. The setup takes about five minutes and runs entirely on your own server.

Skip the automation middleman

Rather than routing data through a third-party cloud, AFI sends it directly from your WordPress server to Smartlead. No task meter, no monthly bill.

What you will need

  • A WordPress site with Ninja Forms installed and at least one form.
  • A Smartlead account.
  • The Advanced Form Integration plugin (free from WordPress.org).

Connect Smartlead to AFI

  1. Log in to your Smartlead account.
  2. Go to Settings → API and copy your API Key.
  3. In WordPress, go to AFI → Settings → Smartlead.
  4. Paste the API Key and click Save Changes.

Setting up the integration

1. Create a new integration

Go to AFI → Add New. Name it Ninja Forms to Smartlead.

2. Pick your trigger

Select Ninja Forms as the form provider and choose the form you want to connect. AFI detects the fields automatically.

3. Select Smartlead as the destination

Choose Smartlead from the platform dropdown and pick Add Lead. This adds a lead to a Smartlead campaign.

4. Map fields

Match each Smartlead field on the left to the corresponding Ninja Forms field on the right. You can also use smart tags like {{_submission_date}} and {{utm_source}}.

5. Add conditions if needed

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

6. Save and test

Click Save Integration. Fill out your Ninja form and submit. Check Smartlead 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 Smartlead with unlimited submissions. Pro adds custom field mapping and campaign selection. No per-submission fees on any plan.

Frequently asked questions

Do I need coding skills?

No. Everything is configured through a visual interface, including field mapping.

Will adding this slow down my form?

No. AFI sends data to the destination after the form submission completes. Your visitors see the normal success message without any delay.

Can I connect multiple Ninja Forms?

Yes. Create a separate integration for each form, or send one form to multiple platforms.
