Email marketing works best when it's driven by data, not guesswork. The Email Split-Testing Workflow, an Agent.so guide, gives you a step-by-step framework to test and improve your campaigns with clarity and confidence.

Whether you're aiming for more opens, clicks, or conversions, this guide helps you uncover what actually moves the needle.

With structured experimentation, you can stop guessing and start sending emails that perform better, every time.

Design smarter tests that lead to real results

This guide starts with the basics of effective A/B testing. You'll learn how to properly set up experiments and choose variables that matter most, such as subject lines, content blocks, send times, and calls to action.

The included ICE framework (Impact, Confidence, Ease) helps you prioritize what to test first, so your decisions are strategic and backed by results.

Instead of relying on hunches, you’ll use a system that supports measurable improvement in every campaign.

Stay consistent with a repeatable testing workflow

Email testing is not a one-time fix. It's a continuous system for growth. This Agent.so guide includes a 90-day testing calendar, easy-to-use tracking templates, and real-world examples that show how small changes can lead to big gains.

You’ll also learn which metrics truly matter, like conversion rates and engagement, so you’re optimizing for meaningful outcomes, not vanity stats.

Whether you manage your own list or oversee campaigns at scale, this workflow makes testing easier, smarter, and more impactful.

Use this guide to simplify your testing process, improve every email, and grow your business with full confidence in what works.
