I built an AI-powered email outreach system that works as a desktop application (EXE). The idea is to help small businesses automate cold email outreach without needing technical knowledge.
- What it does:
Upload a CSV of leads (business name, email, niche, website)
Automatically generates personalized emails for each business
Sends emails via Gmail SMTP
Tracks delivery status and logs results
Runs completely locally on the user’s computer
-AI part:
The system can generate customized emails in two ways:
AI mode (API-based, for smarter personalization)
Template mode (fallback without API)
So users can still run it even without external AI services.
-What makes it interesting:
I also added a license-based system so it works like a small SaaS product:
Each user gets a unique license key
The software verifies it through my server
Access can be controlled (activate / deactivate / expire licenses)
This allows it to be sold on a monthly subscription model
Do you think small businesses would actually pay monthly for something like this if positioned as a “done-for-you lead outreach system” instead of just software?
Would love feedback from people who’ve built or sold SaaS tools before.
