ProSignify is a modern email signature editor designed to help individuals, freelancers, and businesses of all sizes create professional, branded, and consistent email signatures—without the need for design or coding skills.

Hey Product Hunt! 👋 I built ProSignify because I was frustrated with how complicated it was to create a professional email signature that actually worked across different email clients. What makes ProSignify unique is our AI-powered analysis engine - it doesn’t just help you build signatures, it actually analyzes them and gives you evidence-based recommendations to improve performance. For example, it can predict that adding a clear call-to-action button could increase your email click-through rates by up to 371%. The thing I’m most proud of? We’ve solved the biggest pain point - compatibility. Your signature will look perfect whether someone opens it in Gmail, Outlook, Apple Mail, or any other client. No more broken formatting or missing elements. What’s new compared to other tools: • Real-time AI analysis with performance predictions • Evidence-based recommendations backed by actual studies • Multi-language support (English, Czech, German) • Advanced team management for businesses • One-click export for any email client We’ve already helped thousands of professionals create signatures that not only look great but actually drive results. Would love to hear what you think! Any questions about email signatures or the tool? Happy to help! 🙂

Okay, ProSignify looks truely awesome! That AI-powered analysis engine with the performance predictions is kinda genius tbh – turning a signature into a conversion tool is a game changer. Super impressed you solved the compatibility nightmare too. How does the AI evolve its recommendations over time, based on new data or trends?
