Overview

Many site owners collect leads through a form and then copy the details into their email system by hand, or rely on extra plugins and custom code to bridge the two. This plugin removes that step. When someone submits a Ninja Form, the data is sent to your Kit account as a new subscriber, based on how you set up the form action.

You map form fields to subscriber emails, tags, sequences and custom fields, so each submission arrives organized the way you want it. Each form action can use its own Kit credentials, which helps if you run several brands or campaigns. It suits bloggers and online entrepreneurs who already build forms with Ninja Forms and want their email list to grow from them.

Features

  • Direct connection to Kit: Sync your Ninja Forms with your Kit account so submissions are sent to your email marketing CRM automatically, without copying subscriber details by hand.
  • Field and feature mapping: Map subscriber emails, tags, sequences and custom fields to your form fields, so each submission is transferred exactly as you have mapped it.
  • Multiple Kit accounts: Action-level credentials let you connect a different Kit account for each form action, which is useful when you manage several campaigns or brands.
  • Automatic tags and sequences: Apply tags and add subscribers to chosen sequences based on their form submissions, so your audience is segmented as people sign up.
  • API debugging: Troubleshoot integration problems through your Kit account API, which helps you find and fix issues with data transfer between your forms and Kit.
  • No custom coding needed: The plugin is built to work with WordPress and Ninja Forms, so you do not need custom code or third-party connectors to keep the integration running.
  • Organized subscriber data: Because every submission follows your mapping, you build a detailed, tidy subscriber database that is ready for targeted email campaigns.
  • Required field indicator: Required fields in the Kit action are marked with a required indicator, so it is clear which settings must be filled in before the connection works.

Best for

  • Bloggers building an email list from site forms
  • Online entrepreneurs already using Ninja Forms
  • Agencies managing several brands or Kit accounts
