Recipient Finder

Never search through old emails again. Recipient Finder instantly suggests email addresses from your mailbox history.

Recipient Finder is a privacy-first Outlook add-in that helps you quickly find and add email recipients while composing messages. It builds a fast, local index of past senders so you can find the right contact in seconds—without leaving your compose window.

Key Features

• Instant search — Type a name, email, or domain and see matches immediately.
• One-click adding — Insert recipients directly into To, Cc, or Bcc.
• Privacy-first design — Your sender index stays on your device; we do not transmit it to our servers.
• Smart indexing — Configurable limits (500–5,000 senders) with automatic updates.
• Works offline — Once indexed, search continues to work without an internet connection.
• GDPR controls — Export or delete your data anytime with one click.

How It Works

1. Sign in securely with your Microsoft account (Microsoft Entra ID).
2. Recipient Finder scans your Inbox for sender information (you control the cap).
3. Contact data is encrypted and stored locally in your browser.
4. Search and add recipients instantly while composing emails.
5. Only licensing and diagnostic pings are sent to our servers—your sender index is not.
