Canary Mail vs. Spark Mail in 2026: Which to Use on Your Mac

Choose Canary Mail if you need encrypted email on your Mac: its Pro+ plan adds PGP and SecureSend for $100 a year, and Spark Mail lists no PGP option. Choose Spark Mail if you work with other people or want the deeper AI assistant, with shared inboxes, assignments and Meeting Notes. Both are free to start.

These two apps get compared constantly and they barely want the same customer. One is built around what can't leak; the other is built around getting a busy inbox and a team through the day. So the useful question isn't which has more features. It's which problem you actually have, and how much of the bill you'd be paying for things you'll never open. Below: price, security, AI, team tools and a one-week way to decide on your own mail.

What does Canary Mail cost compared with Spark Mail?

Canary Mail is the cheaper paid app: Growth is $36 a year and Pro+ is $100 a year, against $99 and $199 for Spark Mail's Plus and Pro. The catch is billing. Canary doesn't sell monthly subscriptions, so the "$3 a month" you'll see quoted is a yearly charge divided by twelve. Spark does offer monthly plans at $10 for Plus and $20 for Pro, which is handy if you only need it for a project.

Those tiers don't line up one to one, and that's where a price comparison can mislead you. Canary's $36 buys AI Copilot, full read receipts, Send Later, calendar and the inbox cleaner. Its encryption and phishing tools only arrive at $100. Spark's $99 buys Spark +AI, templates, integrations and 40 Meeting Notes a month. Read Statuses, Auto-Drafts and unlimited Meeting Notes only arrive at $199.

I run three addresses: a personal Gmail, a work one and an old iCloud account I can't quite retire. Both free plans would hold all three, so account count shouldn't decide this for anyone. The free plans are worth more than most people assume, and I wouldn't pay for either app until a specific missing feature annoys me twice.

Is Spark Mail cheaper through Setapp?

Spark Mail through Setapp is only cheaper if you'll use Setapp's other apps too. Setapp says you get Spark Plus inside its membership, and its Mac plan is $14.99 a month plus tax for one Mac. That's $179.88 a year, against $99 for Spark Plus bought directly. Setapp says yearly billing can save up to 40%, which would still land around $108. The bundle earns its price when you'd use a couple of other apps from it, not as a way to buy email.

One more price worth checking: Canary's Mac App Store listing shows a Growth Lifetime Bundle at $99.99, which its pricing page doesn't list. If you hate subscriptions, look at what's on offer in the app before you commit to a yearly plan.

Which is more secure, Canary Mail or Spark Mail?

Canary Mail is the stronger choice for security because it offers end-to-end encryption with PGP and SecureSend, on its Pro+ plan. Spark Mail's pricing and features pages list no PGP or end-to-end option, and Canary's own comparison says Spark doesn't offer either. That second source is a rival, so weigh it as one, but I haven't seen Readdle claim otherwise.

End-to-end encryption also takes two people, and that's the part buying the app won't solve. PGP, a long-standing way to encrypt email in which each person holds a pair of keys, only works when your recipient has keys too. Canary's help center says they don't need Canary, just PGP from some other tool. When I send a contract to outside counsel, they almost never have a PGP key, and I'm not going to ask a lawyer to install one for a single PDF.

That's the case SecureSend covers. The recipient gets a secure link instead of a normal email, verifies who they are, and reads the message in a browser, with no app or account to set up. Canary's security page adds that these messages can expire and be revoked. For most people on Pro+, I suspect SecureSend will get far more use than PGP.

If your company runs on S/MIME, the certificate-based encryption some employers require, stop here: Canary doesn't support S/MIME on any platform, Mac included. Our guide to sending encrypted email on a Mac covers the apps that do, and this roundup of secure Mac email clients goes wider than these two.

How to turn on PGP in Canary Mail on a Mac

Canary's PGP setup on macOS has a manual mode for people who already have keys, and it takes a few minutes if you do. These steps come from Canary's Mac guide.

1. Open Canary Mail > Settings > Security.
2. Under PGP, turn on the toggle.
3. Open Settings > Security > Keys to reach the Key Manager.
4. Click Import and pick your .asc key file, or click + to generate new keys.
5. Click None next to the key and choose the mail account it belongs to.

Which app handles your data better?

Canary Mail keeps less on company servers by default, though Spark Mail's policy keeps less than you might expect. Canary's privacy policy says email content and credentials stay on your device on Mac, iOS and Android, with temporary server storage only for push notifications and Cloud Sync. Spark's policy, updated September 10, 2026, says your device does most of the mail processing, and its systems step in only when a feature needs them.

Spark Mail's detail is worth reading, because it's specific. Recent emails stay on its systems for four hours, Send Later messages until they go out, and emails shared by link until you delete the link or the account. Readdle says it stores login credentials as a token it can't retrieve, and that it doesn't sell your personal information.

Neither app keeps all your mail away from cloud AI once you ask for AI help. Canary's policy says writing, summaries and chat use cloud-hosted models from outside providers, while its personalized prioritization models live on your device. Spark uses a mix of on-device models and outside providers, which may hold inputs as long as 30 days to monitor abuse. Both say your data doesn't train AI models. In practice, if a thread shouldn't leave your Mac, don't run AI over it in either app.

The Mac App Store labels point the same way, as far as they go. Canary's listing shows no data linked to you; Spark's lists contact info, user content including emails, and a device ID as linked to you. Developers write those labels themselves, so treat them as a statement rather than an audit.

The read receipt catch in Canary Mail

Canary Mail blocks tracking pixels in the mail you receive and uses one in the mail you send. Its security page says invisible trackers are blocked by default across every account. Its technical overview says read receipts work through a small invisible image loaded from Canary's server, and its Mac help page says those receipts are on by default.

That isn't a scandal. Canary says it logs only the open and the time, with no IP address or location. But a privacy-minded buyer should know their outgoing mail may carry a pixel until they switch it off, under Preferences > Read Receipts in Canary's wording. I don't want one in a note to a client who has asked me about their data. Readings aren't exact either: Canary warns that Apple's Mail Privacy Protection can make them inaccurate, and blocked images mean a message just stays "Not yet read."

Canary Mail AI vs. Spark Mail AI: which does more?

Spark Mail's AI does more, and Canary Mail's costs less. Canary's AI Copilot drafts replies, suggests subject lines, rewrites for tone, summarizes threads and searches in plain language, starting at $36 a year. Spark +AI covers similar writing and summary work on Plus at $99, with 40 Meeting Notes a month and an AI Assistant. Pro adds Auto-Drafts and lets the assistant work across your full email history.

Auto-Drafts is the feature most likely to change your day. When an email from a real person seems to need an answer, Spark saves a suggested reply in your Drafts folder, and Readdle states that it never sends one on your behalf. On a Mac you turn it on per account under Spark Settings > Spark +AI > Inbox Automation. It's a Pro feature, and Readdle says it's rolling out in phases on desktop.

Watch the meter on both. Spark's pricing page describes AI use as monthly credits, "extended" on Plus and "high" on Pro, without a number. When you run out you wait for the refill or buy an add-on, and the Mac App Store listing shows those at $4.99 and $9.99. Canary's pricing page states no cap at all, which isn't the same as promising there's none. Either way, AI stays out of your way until you want it: Spark +AI starts switched off, and Canary's can be disabled.

Mac users who run AI agents have one more thing to look at. Spark added a command-line tool in 2026 that gives agents read access to mail, calendar, contacts and meeting notes, and triage access is listed under Pro. I haven't seen Canary advertise an equivalent, so treat that as a Spark-only feature for now.

Which is better for working in a team?

Spark Mail is the better choice for teams because team email is what it's priced and built around. Its features page lists Shared Inbox, Shared Draft, Assignments, Team Comments, Share Thread and Shared Templates. The team pricing page gives Free teams 2 active collaborators and 10 assignments, so a pair can try it for nothing. Spark's pages don't make clear which plan includes shared inboxes, so confirm that before you count on one.

Assignments solve a problem I've caused more than once. I forward a client thread to a colleague with "can you take this?", and an hour later we've both replied with slightly different answers. With an owner on the thread and a private comment beside it, that conversation stops happening in the client's inbox.

Canary Mail is harder to read here. Its features page lists Shared Inbox, Assignment, AI Routing and team Analytics, yet its pricing page sells only single-user licenses, tied to "one individual user, not a team or organization." If you want Canary for a team, ask them what that costs before you plan around it.

Which feels better for everyday email on a Mac?

Spark Mail suits people who want the app to sort their mail, and Canary Mail suits people who want one plain list they can clear. Both need macOS 12.0 or later, both are free downloads on the Mac App Store, and both have a Windows, iPhone and Android version if your work moves around.

Spark Mail's day-to-day

• Smart Inbox splits mail into People, Notifications, Newsletters, Priority, Pins and Seen, so a receipt doesn't sit beside a question from your manager.
• Gatekeeper holds first-time senders for you to accept or block. It's a paid feature; on a Mac, press Command-comma, then choose Inbox > Gatekeeper.
• Command Center opens with Command-K, and Settings > Shortcuts offers presets for Apple Mail, Gmail and Superhuman. That last part is a kindness if your fingers already know another app.

Canary Mail's day-to-day

• Unified Inbox with VIP, Unread and Mark as Done views, built for an Inbox Zero habit.
• Bulk Cleaner sits behind the magic wand icon: it selects messages as you scroll, then applies one action to the lot. Canary's plans list an Inbox Cleaner from Growth up, so expect to pay for it.
• Read receipts, templates, snooze and pins are on every plan, with a Lite version of receipts on Free that Canary's pricing page doesn't define. Send Later needs Growth.

My own Monday morning is the test I'd apply. When I open my laptop to dozens of new emails and most are newsletters and notifications, Spark's sorting does real work before I read a word. When there are only a handful and all of them matter, sorting just gives me more places to look, and a single list wins.

Canary Mail vs. Spark Mail: which should you choose?

Pick by the thing you can't do without, because neither app is a clear overall winner. This table covers the common reasons people end up comparing them.

If nothing in that table made you sit up, you may not need either. Apple Mail is free and already on your Mac, and we've compared it directly with Canary and Spark. And if you're mainly trying to get away from Spark's AI quota or its servers, our Spark alternatives page starts from that reason.

How to test both apps on your Mac in a week

The best way to choose between Canary Mail and Spark Mail is to run each on your real mail for a few days, since both connect to your existing accounts and leave your address where it is. Canary lets you try every Pro+ feature for 7 days, SecureSend included, with no card, then drops you to Free. Spark's Plus and Pro have a seven-day trial when you subscribe in the app, so put a reminder in your calendar for day six.

1. Install both through the Mac App Store and add the same one account to each. Start with your busiest address.
2. Start Spark's Plus trial in the app, then use Spark Mail alone from Monday to Wednesday, with its AI on and Gatekeeper set to its default.
3. Use Canary Mail alone from Thursday to Saturday, with Copilot on. Check the read receipt setting first if you'd rather not send pixels.
4. Write down anything you missed from the other app. One line is enough.
5. Send one sensitive message from Canary with SecureSend to a friend, if encryption is why you're looking, and ask whether they could open it without help.
6. Pick the app with the shorter list, then make it your default email app and sign out of the other one.

Keep Apple Mail or your webmail open during the test. A new client shouldn't be the only way you can reach your inbox on the day it misbehaves.
