Aegis Mail is the iPhone client for Aegis — business email on your own domain. MAIL THAT IS ALREADY THERE Messages, folders and bodies are kept on the device. A folder is on screen before the request goes out, and a message is drawn the moment you tap it rather than after a spinner. EVERYTHING A MAILBOX NEEDS • Several mailboxes at once, and one unified inbox across all of them • Conversations, labels, snooze, and a reminder list for what comes back later • Search a folder, or search the mail screen itself to find a folder or label by name • Swipe actions you choose for each side • Replies with formatting, inline images and attachments • Signatures per address, including shared and delegated mailboxes • Send as a shared address, when your administrator has granted it • Out-of-office replies, set on the server, so they answer while your phone is off • Rules, templates, blocked senders and muted conversations • Calendar with day, week, month and agenda views, invitations and reminders • Contacts from the server address book • Push notifications the moment mail arrives • Face ID or Touch ID lock, with the delay you choose • Dark mode, Dynamic Type, VoiceOver • English, Russian and Azerbaijani NO ONE READING OVER YOUR SHOULDER No advertising, no tracking, no analytics libraries, and nothing about your mail leaves the app except to your own mail server. Aegis Mail needs an Aegis mailbox. Mailboxes are created by the administrator of your domain.

Verdict
The clearest difference is in-app purchases: Aegis Mail at none against Calendo's 1. Aegis Mail also leads on ads (none vs shown). Calendo's advantage is device support (3 vs 1). On price, update cadence and iOS requirement there is nothing between them.
