Zimity is a digital privacy platform designed to help people understand and manage who can reach them online. By connecting an existing inbox, users can map companies, services, and individuals that already hold their email address, then manage those connections from a central dashboard. Zimity says this discovery uses email metadata rather than reading message content.

For ongoing privacy, the platform offers persistent Smart Aliases, self-expiring Burner Aliases, and custom XID subdomains, allowing users to share alternative email addresses. Its connection controls include blocking senders, scheduling delivery, setting message limits, favouriting important contacts, assigning VIP alerts, and tying an alias to a specific sender to help identify when an address may have been shared.

Zimity Speak provides private conversations without requiring a phone number or a guest account. Users can configure options such as messaging, voice and video calls, media sharing, screenshots, and conversation duration, including an instant kill switch. The platform works with major inbox providers that support IMAP, including Gmail, Outlook, iCloud, Yahoo, and AOL.
