Overview
Collecting email addresses by hand, or copying them from form entries into Mailchimp, takes time and invites mistakes. Ninja Forms MailChimp removes that step. You connect your Mailchimp account with its API key, choose an audience or group, and map your form fields to the data Mailchimp expects. New subscribers then arrive in your list as soon as the form is sent.
The add-on works with the core Ninja Forms plugin, so you build signup forms the same way you build any other form. You can create as many signup forms as you need and place them anywhere on your site. Options such as double opt-in, an opt-in checkbox, tags and conditional logic let you decide who joins which list and how they are asked for consent, without writing code.
Features
- Mailchimp account connection: Link your WordPress forms to Mailchimp with your API key, so submissions sync to your account and new subscribers are added directly from your website.
- Unlimited signup forms: Create as many Mailchimp signup forms as you need and place them across your site, each with its own styling, layout and field presentation.
- Audience and group mapping: Pick any Mailchimp audience or group and map form fields to it, including tags, custom fields and the data your lists and interest groups ask for.
- Per-form double opt-in: Turn on double opt-in for individual forms, so you can require confirmation from subscribers on the forms where you want it.
- Mailchimp opt-in field: Add a checkbox that visitors can select to join your list, which makes consent clear at the point of signup.
- Conditional logic for lists: Use conditional logic to add subscribers to specific lists or groups based on how they answer your form, creating targeted segments.
- Custom confirmation messages: Send or display a confirmation message after a successful signup, so visitors know their subscription went through.
- Refreshable Mailchimp lists: Refresh your connected lists from inside the plugin so you are always working with your current Mailchimp audience data.
Best for
- WordPress sites that already use Ninja Forms
- Site owners managing several Mailchimp audiences or groups
- Marketers who segment subscribers by form responses
