I built a free open-source tool to automate cold emails β€” feedback welcome πŸš€

One of the hardest parts of being a solopreneur (at least for me) is outreach. Copy-pasting emails from a CSV and tracking which ones worked was eating my time.

So I built a simple open-source Python tool: TrinidiumLab-v1.

  • Import leads from a .csv
  • Send emails via Gmail API
  • Logs sent & failed emails into text files
  • Configured safely with .env + credentials.json

It’s super basic (my first public release), but it saves me a ton of time. Thought I’d share here in case anyone else is struggling with manual emailing.

πŸ”— GitHub Repo: github.com/Devankattrinidium/TrinidiumLab-v1

Planning a v2 with scraping + AI personalization, but for now would love feedback:

  • What features would make this actually useful to you?
  • Any pain points in your outreach workflow?

Appreciate any thoughts πŸ™Œ
