NetSendo v1.6.6: Advanced A/B Testing & Visual Editor

In digital marketing, assumptions are expensive. Guessing which subject line will perform best or which call-to-action will drive more clicks can lead to missed opportunities and wasted resources. The only way to truly know what works is to test. That's why we're thrilled to announce the release of NetSendo v1.6.6, a game-changing update focused on data-driven optimization.

This release introduces an enterprise-grade A/B Testing system directly into the platform, giving you complete control over your campaign optimization. We've also added a full visual editor for HTML templates, making customization easier than ever. Take control of your marketing stack and start making decisions based on data, not guesswork.

🚀 What's New in v1.6.6

This update is packed with features designed to enhance your workflow and boost your campaign performance. Let's dive into the details.

Enterprise-Grade A/B Testing

Move beyond simple subject line tests. Our new A/B testing suite is built for professional marketers who demand robust features and statistical accuracy. It’s an integrated solution that gives you the power to test nearly every aspect of your email messages.

ℹ️ Note: The Control Variant (A) is locked to your main message content to ensure a consistent baseline for all your tests. Use our new AI Assistant to generate creative ideas for your other variants!

Full HTML Visual Editing

Tired of switching between your code editor and NetSendo to tweak your HTML templates? Now, you can edit your full HTML templates directly in our visual editor. Just click on any text element to edit it in a simple modal, complete with variable insertion and live previews.

This new functionality streamlines the template editing process, saving you time and reducing the friction between design and implementation. Hover highlights guide you to editable elements, making the experience intuitive and fast.

UI Enhancements & Key Fixes

We've added a new A/B test indicator (🧪) to the Messages list, giving you an at-a-glance view of a campaign's test status—from draft to completion. We also fixed a crucial API endpoint, resolving a 404 Not Found error for our WordPress and WooCommerce plugin users and ensuring smooth pixel tracking.

🎯 Benefits & Use Cases

Here’s how you can leverage these new features in real-world scenarios:

🛠️ Step-by-Step Guide: How to Set Up Your First A/B Test

Ready to get started? Launching an A/B test in NetSendo is straightforward. Follow these steps:

1. Create Your Message

   Start by creating your email message as you normally would. This will serve as your "Control" or Variant A. Fill out the subject, preheader, and content.

2. Enable A/B Testing

   In the Message Creator, find the A/B Testing Panel and toggle it on. The panel will appear, allowing you to configure your test.

3. Add and Configure Variants

   Click "Add Variant" to create Variant B. Choose what you want to test (e.g., "Subject"). Enter your alternative subject line. You can add up to 4 additional variants (for a total of 5).

4. Set Test Parameters

   Define your test settings. Choose the sample size (e.g., 20%), the test duration (e.g., 4 hours), and the metric for selecting a winner (e.g., Open Rate).

5. Launch Your Campaign

   That's it! Schedule or send your message. NetSendo will handle the rest: sending the variants to the sample audience, monitoring the results, and sending the winning version to the remaining subscribers automatically.

💡 Expert Tips

⚠️ Important: A/B testing is most effective with larger list sizes. If your list is small, consider using a larger sample size percentage to gather enough data for a meaningful result.

Conclusion: Optimize, Don't Guess

NetSendo v1.6.6 puts powerful, data-driven optimization tools directly in your hands. With enterprise-grade A/B testing and a streamlined visual editor, you have everything you need to refine your strategy, boost engagement, and maximize your ROI—all from your self-hosted platform.
