See our email testing feature in action
TestFeed's email testing tool predicts how recipients will respond to your important emails before you send them. No more guessing or obsessing - just clear insights that help you write with empathy and confidence.
Hi there,
I noticed your company is growing quickly, and I wanted to reach out about how we might be able to help with your team's collaboration challenges.
Would you be interested in a quick call next week to discuss?
Thanks,
Sarah

You spend hours crafting partnership outreach, client proposals, or important cold emails, but never know how they'll be received until it's too late.
Without feedback, you're left wondering why your emails are ignored or why they receive unexpected responses that kill promising opportunities.
You rewrite, get colleague feedback, run it through AI, and still hit send with nagging doubt about whether it's the right approach.
Describe a specific person (like 'the CMO considering our proposal') or an avatar ('marketing directors at SaaS companies').
Test a single email draft or compare two versions if you're torn between different approaches.
We simulate that person receiving your email 100 times in different mental states (busy, distracted, focused) and show you meaningful predictions about their likely response.
Will they open your email in the first place? See open rate predictions based on your subject line and sender information.
Understand the probability of receiving a response and what factors are influencing their decision to reply or ignore.
View simulated replies that represent how recipients might respond - both positive and negative scenarios.
Peek inside their mind to see what they're really thinking, even when they respond positively or choose not to reply at all.
Identify potentially problematic phrases, tone issues, or missing information that could reduce your chances of success.
Test two approaches head-to-head and see which one is more likely to achieve your communication goals.
Test outreach emails to potential partners or high-value clients where the initial communication can make or break the opportunity.
Refine fundraising emails or updates to investors where clear, effective communication is essential for building confidence.
Evaluate cold emails to industry influencers, potential mentors, or important contacts where you only get one chance to make an impression.
Test sensitive communications during negotiations to ensure your message conveys the right tone and expectations.
Our email testing tool provides directional guidance rather than perfect predictions. While no simulation can account for every variable in human communication, our tool gives you valuable insights into potential recipient reactions and areas for improvement that dramatically increase your chances of success.
Unlike general AI writing tools that focus on improving your writing style, our technology simulates how real people in different mental states would actually respond to your message. It's the difference between someone telling you 'this sounds good' versus showing you precisely how it will be received.
Email testing is currently in R&D stage and available to a limited group of beta testers. Join our waitlist to be notified when it's ready for wider release.
Yes! The tool allows you to specify exactly who you're emailing, whether that's a specific individual or a broader recipient persona. This customization ensures predictions are relevant to your unique communication scenario.
