About
ONYX Mail is the official app for mailboxes hosted on ONYX's own mail servers — fast, private, and built natively for iPhone. Sign in with your address and go straight to your inbox.
• Conversation view, search, stars, and all your folders — including Scheduled and Snoozed mail
• Swipe to archive or delete, select several messages at once, and undo
• Rich composer with bold, italics, lists, CC/BCC, contact suggestions, and photo and file attachments
• Send files too large to attach as download links
• Drafts save automatically
• Face ID and Touch ID app lock
• New-mail notifications, with an option to hide the sender and subject
• Remote images stay blocked until you choose to load them, so senders can't tell when you open their mail
• Server-side filters and labels, signature, and auto-reply, edited right on your phone
• Several accounts, with light, dark, and system themes
Your mail stays between your device and your ONYX mail server. No ads, no tracking, no data sharing.

ONYX Mail, faster and closer to Gmail: • A new envelope icon. • The conversations at the top of your inbox open instantly, and a message draws as it opens. • Lists show their shape while they load instead of a spinner. • Compose starts at To and writes above your signature; replies carry your signature too. • Search opens ready to type, and a long press selects a message. • Email links in other apps open the composer, filled in. • Print a conversation, and View in light theme in dark mode. • Folders offer quick filters: Has attachment, Unread, Starred, Last 7 days. • Spam and Trash can be emptied in one tap; empty folders show a friendly picture.
