TrailMail

Predict work emails on LinkedIn from public company patterns, save templates, and send them from your own Gmail — no backend.

Stop burning a lookup credit on every single email. TrailMail spends just ONE Hunter.io credit per company. It reads that company's verified email pattern once, then generates a predicted work email for everyone on the LinkedIn page - up to 15 per scan - for free. Your free Hunter.io tier (50 lookups/month) becomes hundreds of emails. Then send a personalized template to the people you pick, straight from your own Gmail. All in one tab. Why TrailMail 💳 1 credit → up to 15 emails — one company lookup covers the whole team ⚡ Verified-pattern predictions — anchored to the company's real email pattern, cross-checked against multiple records 🎯 Confidence on every result — HIGH / MEDIUM / LOW, so you know what to trust ✍️ Templates with merge tags — {First}, {Company}, {Role}; write once, personalize each send 📨 Sends from your Gmail — one email per person, from your account, in your Sent folder 📋 Export anytime — copy to clipboard or download CSV in one click Privacy first: Runs entirely in your browser. No server, no data collection, no third-party storage. Gmail access is send-only and cannot read or touch your mailbox. What you need • A free Hunter.io API key — and each credit covers a whole company, not one email • Gmail sign-in for sending Heads up Predicted emails are not verified and some may bounce.
