Cobalt Mail

Private by design: no ads, no analytics, no Cobalt Mail servers. Just a direct, encrypted connection to your own IMAP/SMTP email account.

Cobalt Mail is a fast, private email client built for IMAP and SMTP — connect the accounts you already have, on your own terms.

No sign-up, no third-party account linking, no ads. Cobalt Mail talks directly to your mail provider's IMAP and SMTP servers using the credentials you already have, the same way email has worked for decades.

FEATURES

• Add multiple email accounts via standard IMAP/SMTP — works with virtually any provider that supports these open protocols • Inbox, Sent, and Trash out of the box, plus your full folder tree for providers with custom folders and labels • Read messages in plain text or HTML, with inline images and file attachments • Compose, reply, and forward messages with attachments, sent securely over SMTP • Messages and folders are cached on your device for fast, offline reading • Credentials are stored in your device's secure Keychain, never in plain text

PRIVACY BY DESIGN

Cobalt Mail doesn't run its own servers, doesn't include analytics or ad tracking, and never sees your email — your data goes straight from your provider to your device, over an encrypted connection.

Cobalt Mail syncs when you open the app or pull to refresh. It's a calm, focused inbox, not a notification firehose.
