# Turn Complaint Emails Into a Response Library — Free

Paste a batch of complaint emails and this sorts them by type — refund, late, rude, broken — and drafts a response template for each. Runs locally.

**Free and complete.** This guide is a standalone free tool — no account, no card, anywhere. The only paid option is one optional extra outcome: $4 one-time. Nothing in the free tier is gated.

## Who it's for

Small teams who answer the same complaints by hand, one by one, and want a library instead

## What's free

- Sort complaints into type lanes
- Draft a response template per type
- See which type costs you the most time

## Optional paid add-on

**$4 one-time.**

- Response-sheet export — templates as a clean sheet — estimate: ~20 min saved.
- Saved library shelf — libraries per product line — estimate: ~12 min saved.
- Lane-count log — track which type is growing — estimate: ~10 min saved.

## Sources & verification

- Tool: Local complaint sorter (no model needed)
- Primary source: the free tool itself (local-first, no external dependency)
- Last verification: 2026-09-12 (green)
