SipherMail is private email with AI built in. Read less, reply faster and keep control of your inbox, on your phone, tablet or foldable.

PRIVATE BY DESIGN
• End-to-end encryption between SipherMail users. Messages are encrypted on your device before they leave it, and the server stores only ciphertext.
• Expiring messages, with an optional password that only you and your recipient know.
• Known tracking pixels are removed from incoming mail, and remote images load through a privacy proxy.
• Privacy mode switches off every AI feature in one tap.
• Lock the app with your fingerprint, face unlock or a passkey.

AI THAT WORKS FOR YOU
• Thread summaries that turn a long conversation into a few lines.
• Smart replies: suggested responses you can edit before sending.
• Rewrite a draft in the tone you want.
• Translate a message without leaving the thread.
• Extract tasks and key dates from a conversation.
• Ask a question about a message and get the answer in place.

A CALMER INBOX
• Conversation view that keeps every reply together, with quoted text folded away.
• Search across all your mailboxes.
• Folders, starred mail and archive.
• Connect more than one account and read them in one place.

SWITCH WITHOUT STARTING OVER
• Import your mail from another email service. For the biggest services you sign in on their own page, so SipherMail never sees your password. Any other service works with its IMAP details.
• Your old account is left untouched, and importing again never creates duplicates.
• Bring your contacts from CSV or vCard files.

BUILT FOR EVERY SCREEN
• On a foldable, the layout follows the screen: phone layout when closed, tablet layout when open.
• On tablets and large screens, mailboxes, the message list and the reader sit side by side.

SipherMail is made by Sipher Ltd. AI features may have usage limits that depend on your plan. End-to-end encryption applies to messages between SipherMail users. Mail from other services is not end-to-end encrypted.
