ReplyVault — Instantly Unibox Exporter

Export your entire Instantly Unibox to CSV or JSON, right from your browser. Your data goes only to Instantly — never to us.

Instantly.ai has no bulk export for the Unibox. ReplyVault fixes that: one click exports every email and reply — across all your campaigns — to a clean CSV or JSON file. WHY AGENCIES USE IT • Client reporting: hand over a complete, readable reply history • Backups: your conversations, on your disk, not locked in a dashboard • Analysis: load replies into Sheets/Excel or any tool that reads CSV/JSON • Migrations & audits: take your data with you WHAT IT EXPORTS Timestamp, direction (sent/received), campaign ID and name, from, to, cc, subject, plain-text body, HTML body, thread ID, message ID, sending account. CSV is Excel-ready (proper UTF-8, RFC 4180) with an optional Excel-safe mode that stops spreadsheet formulas from running. JSON is a clean array. FILTERS Whole Unibox, or narrow by date range, campaign, or direction (replies only / sent only). BUILT FOR BIG MAILBOXES Instantly's API allows ~2,000 emails per minute. ReplyVault paces itself at exactly that limit, shows live progress, and can pause and resume — even if the tab closes or the browser crashes, your progress is saved on your device and picks up where it left off. PRIVATE BY ARCHITECTURE ReplyVault runs entirely in your browser. Your Instantly API key and your emails go only to Instantly's own API over HTTPS — the developer runs no servers and receives nothing. No analytics, no telemetry, no remote code. The only other host the extension can reach is our payment provider (api.polar.sh), used solely to check a license key you enter. PRICING Free: export your newest 200 emails, no license needed. $49 one-time: unlimited exports, lifetime license. No subscription. REQUIREMENTS An Instantly.ai account on a paid plan (for v2 API key access). Get your key in Instantly → Settings → Integrations → API.
