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.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
ONYX Mail now works more like Gmail:
• Conversations: replies are grouped into one conversation, including your own.
• Attachments show as chips on each message in the list: tap one to preview it.
• New mail appears on its own, and the app icon shows the unread count.
• Reply all and forward, undo send, and schedule send.
• Move, label, snooze and report spam from the menu or a selection.
• Attachments preview inside the app, and Drafts shows how many you have.
• A faster search with recent searches and filters.
• Your organization's colours and logo, and a full Arabic interface.
• Fixed: pulling down to refresh no longer selects a message.
