Canary Mail Alternative: AI-Sorted Unified Inbox in the Browser
Connect every mailbox you own to one board, in the browser, and let AI read each message to categorize it and flag spam before you open it.
Any IMAP provider · AI category + spam per message · Two-way sync
In short
Canary Mail is a security-minded desktop and mobile email client with a unified inbox, an AI copilot, and PGP encryption, priced from $3 per month billed yearly. Inboxes is a browser-based unified inbox that puts every IMAP mailbox on one board and has an AI model read each incoming message to categorize it and flag spam. Canary is cheaper and has native apps and encryption we do not. Inboxes is the pick when you need automatic triage across many mailboxes from any browser.
The difference
Where Inboxes and Canary Mail actually diverge
Canary Mail built its reputation on privacy: end-to-end PGP encryption, read-receipt blocking, and a promise not to mine your mail. It has since added an AI copilot that summarizes and drafts, and it runs natively on macOS, iOS, Windows, and Android with a unified inbox across Gmail, Outlook, iCloud, Exchange, and IMAP. It is a strong, cheap product. Where people come looking for an alternative is device sprawl and triage. Canary licenses by device (its free tier caps at two, paid tiers at five), and it is an installed app, so the machine you are on decides whether you have your inbox. And its AI is mostly a writing and summarizing copilot you invoke, not a sorter that runs on everything that lands. Inboxes inverts that. There is nothing to install, because the board is a web app, and the AI is not something you invoke: it reads every message at every connected mailbox as it arrives, gives it a category, and decides if it is spam, so the inbox you open is already triaged.

// Where Canary Mail wins
Canary Mail is the better choice on price and on privacy engineering. If end-to-end encrypted mail matters to you, Canary does PGP properly and we do not offer encryption at all. If you want native Mac and iPhone apps with offline access, Canary has them and Inboxes does not. At $3 per month billed yearly for its Growth tier, it costs a small fraction of our entry plan. Pick Inboxes only if the specific thing you need is hands-off AI categorization and spam detection across a lot of mailboxes, reachable from any browser.
FAQ
Questions people ask before switching
What is the best Canary Mail alternative?
If you want the unified inbox without installing an app, and you want the sorting done for you, Inboxes is the closest alternative: it is browser based and runs AI categorization and spam detection on every message. If you want another native client, Spark and Mailbird are the usual comparisons, and Thunderbird is the free open-source option.
How much does Canary Mail cost?
Canary Mail publishes a free tier limited to two devices, a Growth plan at $3 per month billed yearly, and a Pro+ plan at $10 per month billed yearly, with lifetime purchase options. Paid tiers raise the device limit to five.
Does Canary Mail have a unified inbox?
Yes. Canary Mail merges Gmail, Outlook, iCloud, Exchange, and IMAP accounts into a single unified inbox on macOS, iOS, Windows, and Android. The difference with Inboxes is where it runs (a browser, not an installed app) and that AI categorizes and de-spams each message automatically as it lands.
Is a web-based email client safe for multiple accounts?
A web-based client is as safe as its handling of your credentials and mail. Inboxes connects over IMAP, keeps your mail on your own provider rather than migrating it, and uses the AI only to categorize and flag messages. We do not train models on your mail and we do not use it for advertising.
