3 ways to optimize every email you send

Stop guessing what works and start testing what converts. This month we're giving you the complete toolkit to optimize every aspect of your emails—from subject lines that get opened to content that drives clicks. Here's what's new:

AI-powered subject lines: Get attention-grabbing subject line suggestions based on your email content. Write your email, and AI instantly suggests the best subject lines to help you find the right words faster—no more staring at blank subject line fields.

A/B test up to 5 subject lines: Test more variations to learn what really resonates with your audience. Creator Pro subscribers can now test five subject line variations instead of just two, giving you more data to discover exactly what makes your subscribers open.
A/B test your content: Optimize beyond opens by testing different email layouts, CTAs, and content approaches. Available exclusively on the Creator Pro Plan, content testing helps you discover what drives the highest click-through rates and conversions.
