What is Canary Mail?
Canary Mail ships maintenance across four platform lines; features have gone quiet since April.
Canary Mail publishes release notes per platform — Android, iOS, macOS and Windows each on their own version line — and every entry in the current top six is fixes only. The August wave put out iOS 5.22.0 and Mac 5.22.0 within a minute of each other carrying an identical changelog (Advanced View overwriting a custom SMTP username, plus crash fixes), with Android 3.99 alongside them fixing swipe-to-select misfires and PGP key handling. The most recent entries carrying a genuinely new capability are the April 5.19 releases, which let users dismiss unwanted compose suggestions.
What is Superhuman?
Superhuman is rebuilding around the assistant: pre-drafted replies and multi-account MCP.
Superhuman ships small and often, and its releases now split cleanly in two. One half is conventional client work — calendar on Android, multi-day views on iPhone and iPad, personalized availability sharing. The other is an aggressive agent surface: Auto Drafts 2.0 pre-drafts a reply to every message that needs one, and the Mail MCP now drives multiple Gmail and Outlook accounts from Claude, ChatGPT and Codex.
Canary Mail vs Superhuman: editorial side-by-side
Canary Mail
5.0COMMS
Canary Mail ships maintenance across four platform lines; features have gone quiet since April.
◆ Current state
Canary Mail publishes release notes per platform — Android, iOS, macOS and Windows each on their own version line — and every entry in the current top six is fixes only. The August wave put out iOS 5.22.0 and Mac 5.22.0 within a minute of each other carrying an identical changelog (Advanced View overwriting a custom SMTP username, plus crash fixes), with Android 3.99 alongside them fixing swipe-to-select misfires and PGP key handling. The most recent entries carrying a genuinely new capability are the April 5.19 releases, which let users dismiss unwanted compose suggestions.
◆ Where it's heading
This is a mature client in upkeep rather than expansion: across four months of entries, the only line labelled New is a suggestion-dismissal control. Two defect threads recur across platforms — PGP correctness (a key-unavailable fallback on Android, a decryption failure on Windows) and Gmail account-setup crashes — which points at encryption and onboarding as where the real bugs live. iOS and macOS now ship in lockstep with word-for-word identical notes, so those two lines are converging in practice even though the version numbers stay separate.
◆ Prediction
After four consecutive maintenance waves the next release is most likely another cross-platform stability pass; these entries do not show enough to say when the PGP or compose surface gets new capability rather than repairs.
Superhuman
7.5COMMS
Superhuman is rebuilding around the assistant: pre-drafted replies and multi-account MCP.
◆ Current state
Superhuman ships small and often, and its releases now split cleanly in two. One half is conventional client work — calendar on Android, multi-day views on iPhone and iPad, personalized availability sharing. The other is an aggressive agent surface: Auto Drafts 2.0 pre-drafts a reply to every message that needs one, and the Mail MCP now drives multiple Gmail and Outlook accounts from Claude, ChatGPT and Codex.
◆ Where it's heading
The centre of gravity is moving off Superhuman's own client. Each recent release makes the mailbox more usable from somewhere else — first a Codex plugin with prebuilt workflows, then parallel search across every connected account — while in-app work is mostly mobile parity. Superhuman is positioning as the mail layer assistants call, and it names the single-account limit of the first-party Gmail and Outlook connectors as the reason to switch.
◆ Prediction
Expect the MCP surface to keep absorbing the features that only the client could do — Split Inbox triage, Read Statuses, Smart Send are already listed — with the native apps continuing to trail on platform parity.
