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 OpenPhone?
OpenPhone turns Sona into a deployable front-line AI agent with transfers and per-scenario instructions.
OpenPhone is hardening Sona, its AI phone agent, into something businesses can actually put in front of customers. Sona can now route calls to the right teammate when a human is needed, and admins can give it custom instructions per scenario (lead qualification, cancellations, booking) with templates to start from. Around it, the call flow builder keeps maturing: multiple routing setups with quick switching, in-place inbox switching during flow construction, and a Go-to Step primitive for cleaner branches.

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.
OpenPhone
0.0COMMS
OpenPhone turns Sona into a deployable front-line AI agent with transfers and per-scenario instructions.
◆ Current state
OpenPhone is hardening Sona, its AI phone agent, into something businesses can actually put in front of customers. Sona can now route calls to the right teammate when a human is needed, and admins can give it custom instructions per scenario (lead qualification, cancellations, booking) with templates to start from. Around it, the call flow builder keeps maturing: multiple routing setups with quick switching, in-place inbox switching during flow construction, and a Go-to Step primitive for cleaner branches.
◆ Where it's heading
The core bet is an AI-handles-first-contact, humans-handle-edge-cases pattern. Each Sona release is closing a deployment-blocker (instructions, transfers, free trial), while the call-flow tooling underneath is getting more flexible so AI and human routing can coexist in one config. Plan-tier expansion (call hold on Starter) suggests OpenPhone is also chasing volume in the lower segment.
◆ Prediction
Expect Sona to gain CRM-aware context (caller history, deal state) and outbound use cases — proactive callbacks, scheduled follow-ups. Pricing for Sona usage is likely to evolve from a flat add-on toward usage- or outcome-based once volume appears.
