How to Connect Gravity Forms to MailPoet: Complete WordPress Newsletter Guide

Growing a loyal email subscriber base directly on WordPress is one of the most effective strategies for publishers, bloggers, and eCommerce stores. If you use Gravity Forms to capture signups and MailPoet to manage newsletters, having submissions instantly subscribe users without leaving WordPress ensures zero latency, zero monthly SaaS costs, and complete privacy compliance.

In this step-by-step guide, learn how to link Gravity Forms to MailPoet using our direct PHP integration add-on.

Step 1: Verify MailPoet Installation

Make sure the free or premium MailPoet plugin is activated on your WordPress website. Install and activate the Gravity Forms MailPoet Integration Add-on. Because the add-on interfaces directly with MailPoet’s core classes, no external API configuration is needed.

Step 2: Create a MailPoet Subscription Feed

Open your newsletter or contact form, and go to Settings → MailPoet:

• Click Add New to create a feed.
• Target List: Choose which MailPoet list (e.g. Weekly Digest or Customer Newsletter) contacts will be enrolled in.
• Field Mapping: Map the Email Address, First Name, Last Name, and any custom subscriber fields.
• Double Opt-In Setting: Choose whether to send MailPoet’s confirmation email or immediately subscribe the user.
• Conditional Opt-In: Add a condition such as “Subscribe to newsletter checkbox is Checked”.

// Append referral source attribute to MailPoet subscriber
add_filter('ge_mailpoet_subscriber_data', function($subscriber, $feed, $entry, $form) {
    $subscriber['source'] = 'Gravity Forms Lead Form';
    return $subscriber;
}, 10, 4);
