Find the right leads. Approve every one. Let AI personalize — never invent.

Mailer Muse discovers public business contacts from the web, keeps a human approving every lead before it's ever emailed, and uses Claude to rephrase and personalize the master email you wrote — it never invents offers, claims, or pricing on its own.

Discover

Search by keyword and location. Auto-collect candidate URLs (or add your own), extract public contact emails, and validate syntax + MX before anything reaches your review queue.

Review & approve

Nothing enters a campaign until a human approves it. Blacklisted contacts never resurface, and every decision is logged.

Personalize, not fabricate

Claude rephrases the master email you write for each recipient — name, title, organization, city — without inventing offers, claims, or pricing.

Send your way

Send manually over SMTP or via the Brevo (Sendinblue) API. Nothing goes out automatically — every send is a deliberate click.

Track replies

Sync IMAP to pull replies back into the app, matched to the original draft and lead so the whole conversation stays in one thread.

Full audit trail

Every approval, send, and settings change is logged and filterable — nothing happens silently.
