From Idea to Launch: How I Built TailorMails Using Free Tools

🌱 The Beginning

Ever felt stuck sending cold emails manually?

I did. Hours spent researching leads, crafting personalized icebreakers, and still getting poor responses.

I thought: "There has to be a smarter way."

And that frustration sparked TailorMails — an AI tool that writes personalized emails that actually get replies.


🛠️ Building the MVP With Free Tools

I didn’t have a team or funding. Just curiosity, free tool credits, and late nights.

  • Next.js – For fast, SEO-friendly frontend and dashboard.
  • Firebase – Auth, Firestore, serverless functions. Free tier enough to start.
  • Firebase Studio – Rapid UI/UX iteration without hiring a designer.
  • Gemini AI Model – The engine that writes emails.

Basically, I hacked together an MVP that cost $0.


🚀 Sharing Progress Publicly

I started posting weekly updates on Twitter & LinkedIn.

  • New features
  • Tiny wins
  • Failures and lessons learned

Building in public not only kept me accountable but also helped me connect with early users.


📈 Launching on Product Hunt

The big test: Product Hunt.

I knew “just posting” wouldn’t work. So here’s what I did:

  1. Redesigned the landing page – clear, fast, and value-driven.
  2. Added free tools – email opener generator, icebreaker generator, no login required.
  3. Prepared a launch story – why TailorMails exists, not just features.
  4. Reached out to early users & friends – to support votes and feedback.

Result? Real traffic, real signups, and early adopters giving honest feedback.


💡 Key Lessons

  • Free tools can get you surprisingly far.
  • Share your story — people connect with founders, not just products.
  • A Product Hunt launch is feedback gold, not just traffic.

🌍 What’s Next

TailorMails is early, but the vision is clear:

Help founders, sales teams, and freelancers send smarter, human-sounding cold emails.
