AI Follow-up Assistant (Google Sheets + Gmail + AI)
ResultDrafted 4 personalized follow-ups in under a minute, with every lead tracked and none missed
An automation that reminds me who needs a follow-up each morning and uses AI to draft a personal email for each lead.
- Google Sheets
- Gmail
- Google Apps Script
- Gemini AI
The task: Following up is where most leads are lost. I built this for my own client outreach, and it's the same system I can set up for any business that follows up with clients, patients or leads.
What I built:
- A lead tracker, dashboard and activity log in Google Sheets
- A daily 8 AM email listing every follow-up that is due
- One-click AI drafting: each follow-up uses the lead's name, business type and one detail I noticed about them
- Every email is saved as a Gmail draft, so nothing is sent without review
- A quality check on every AI email, automatic retries when the AI is busy, and a backup template so a draft is always ready
The result: A whole list of personalized follow-ups is drafted in under a minute, and no lead is forgotten.
Built with Google Apps Script. If a client prefers n8n, Zapier or Make, I can build the same workflow on their paid plan.

Demo: I click "Check follow-ups due" and overdue leads turn yellow. Then "Draft follow-ups with AI" writes a personal follow-up for each lead and saves it as a Gmail draft, ready to review and send.
