Executive Summary

Many small businesses, sales reps, and non-marketers still run lists and segments in spreadsheets but struggle to send high-quality personalized emails at scale without manual copywork, deliverability problems, or getting throttled/blocked by email providers. The pain is operational (messy exports, manual delays) and technical (provider sending limits, bounce/blacklist risk), which makes outreach inefficient and risky for SMBs. Build a spreadsheet-first product (Sheets add-on + lightweight web app) that reads rows, generates AI-assisted personalized copy, and automatically staggers sends with configurable per-recipient/provider delays, pacing rules, retry logic, and deliverability-aware scheduling. Deliverability monitoring, simple templates, and one-click sync with common ESPs/SMTP would make it usable by non-marketers while keeping control over send reputation. This is a timely opportunity: the TAM is about $6.0B (2M businesses × $3K ACV) and the market scores high (88/100) with strong revenue potential (82/100), driven by AI personalization becoming accessible and stricter provider throttling creating demand for smart scheduling. The spreadsheet-first workflow reduces adoption friction for SMBs who resist complex CRMs, so acquisition costs can be lower if positioned correctly. You can stand out by combining deeply integrated Sheets UX, AI copy that adapts to row-level data, and a deliverability-first scheduler that maps to provider limits and best practices. That said, competition is high and success will hinge on nailing deliverability (IP/domain reputation), building trustworthy provider integrations, and executing on go-to-market to reach the many small buyers.
