The best mail apps for Mac (2026)

Start with Apple Mail. It's free, it's already on your Mac, and it handles Gmail, iCloud, Outlook.com, Exchange and any IMAP account in one window. Switch only for a specific reason: Mimestream if your life is in Gmail, Spark if you need the same inbox on Windows and Android, Outlook if your company runs on Microsoft 365, and Superhuman if speed is worth $25 a month to you.

We make Sayburst, a Mac dictation app, so we're not neutral about how you write email. We are neutral about where you read it: Sayburst types into all of these, and none of them is ours. Prices and platforms come from each vendor's site or Mac App Store listing, checked October 31, 2026. This is desk research from official sources, not a lab test.

#Quick picks

• Free and good enough: Apple Mail.
• Gmail power user: Mimestream.
• Same app on Mac, Windows, iPhone and Android: Spark, or Canary if you want encryption options.
• Microsoft 365 at work: Outlook.
• Keyboard-first speed, money no object: Superhuman Mail.
• Free and open source: Thunderbird.
• Apple devices only, lots of accounts, custom workflows: Airmail.

#At a glance

#How we chose

Every app here is currently available, runs natively on a Mac, and is still updated. We looked at four things:

• Which accounts it handles well. A Gmail-only client can be better at Gmail than a do-everything app.
• What it costs over a year. Several of these are subscriptions; one is free with ads.
• Where else it runs. If you also use a Windows PC or an Android phone, that narrows the field quickly.
• What it does with your mail. Some apps sync through their own servers or offer cloud AI features. Read each privacy policy before connecting a work account.

#The picks

1

Apple Mail

Best for Most people, and anyone who wants zero setup · Price Free

Mail ships with macOS and picks up the accounts you've already added in System Settings. It handles all your accounts from one app, sorts incoming mail into Primary, Transactions, Updates and Promotions, and has Apple's Writing Tools for summarizing or proofreading selected text on Macs that support Apple Intelligence.

Why it's here: it's free, fast, fits macOS perfectly and syncs with Mail on your iPhone through your accounts. For a personal inbox it does the job without another subscription. Trade-off: no shared inboxes, no snooze-and-screen workflow like Spark's, and it only runs on Apple devices.

2

Spark

Best for One inbox on Mac, Windows, iPhone and Android · Price Free; Plus $99/yr; Pro $199/yr

Spark from Readdle is the most complete cross-platform client here. The free plan includes the Smart Inbox, unlimited email accounts and smart notifications. Gatekeeper screens first-time senders, and the paid plans add Spark +AI writing and summaries plus team features like delegating emails and private comments on threads. A subscription bought on one platform works on the others.

Why it's here: the best free option if you move between a Mac and a Windows PC or Android phone. Trade-off: the AI and team features sit on paid tiers, and the per-user pricing adds up for a team.

3

Mimestream

Best for Gmail and Google Workspace on a Mac · Price $49.99/yr or $4.99/mo

Mimestream is a native Mac app built only for Gmail. It talks to Gmail through the Gmail API rather than IMAP, so labels, categories and filters work the way Gmail intends instead of being squeezed into folders. One license covers all your Google accounts on up to five devices, and family sharing is included. It needs macOS 12 or later; an iPhone and iPad version is in beta.

Why it's here: if you'd otherwise keep Gmail open in a browser tab all day, this is the Mac app you wanted. Trade-off: Gmail only, and subscription only, with a 14-day free trial.

4

Microsoft Outlook

Best for Microsoft 365 accounts at work · Price Free with ads; ad-free with Microsoft 365

Outlook for Mac is free with personal accounts: Outlook.com, Gmail, Yahoo, iCloud, IMAP and POP all work. If your employer runs Microsoft 365, it's the client that best matches what IT expects, calendar and all. A Microsoft 365 subscription removes the ads. It requires macOS 14 or later.

Why it's here: free, polished, and the obvious choice when Exchange or Microsoft 365 is involved. Trade-off: ads in the free version, and it's a Microsoft-shaped app rather than a Mac-shaped one.

5

Superhuman Mail

Best for Heavy email users who live on the keyboard · Price From $25/mo billed yearly

Superhuman works on top of your existing Gmail or Outlook account, with apps for Mac, Windows, iOS, Android and the web. It's built around keyboard shortcuts and getting through a large inbox quickly, with AI features on its plans.

Why it's here: if email is most of your job and you answer hundreds a day, it's designed for exactly that. Trade-off: the most expensive app here by a distance, and Gmail and Outlook accounts only.

6

Canary Mail

Best for Encryption and security features without a monthly bill · Price Free; Growth $36/yr; Pro+ $100/yr

Canary runs on Mac, Windows, iOS and Android, and one license covers all of them. The free plan includes a unified inbox, snooze and pin, templates and unlimited accounts on up to two devices. Growth adds AI Copilot, Send Later and scheduling; Pro+ adds PGP encryption and phishing protection. Paid plans are yearly or lifetime, never monthly, with a 7-day trial and no card.

Why it's here: PGP and phishing tools in an everyday client, for less than most subscriptions here. Trade-off: lifetime prices are only shown inside the app.

7

Airmail

Best for Apple-only users who like building their own workflows · Price Free (one account); Pro $49.99/yr or $7.99/mo

Airmail has been a Mac power-user favourite for years. It supports Gmail, iCloud, Exchange, Office 365, IMAP and POP3, with custom actions that chain steps together, Shortcuts and Siri support, a Smart Inbox and a privacy mode that blocks tracking pixels. Pro adds multiple accounts, push, Send Later and snooze. It needs macOS 14.6 or later. Pro prices are from the US Mac App Store listing.

Why it's here: deeper customization than Apple Mail without leaving Apple's ecosystem. Trade-off: the free tier is one account, so most people will end up paying.

8

Thunderbird

Best for Free, open source, and fully under your control · Price Free

Mozilla's Thunderbird is free and open source, funded by donations, and runs on Mac, Windows and Linux, with an Android app. It's the client to pick if you want the same open tool on every desktop and don't want a company in the middle of your mail.

Why it's here: the only open-source desktop client on the list, and it costs nothing. Trade-off: it doesn't feel like a Mac app, and there's no iPhone version.

#Bonus pick: dictate your replies with Sayburst

Not a mail app, but it changes how fast you get through one. Most of the time you spend in email is spent writing, and talking through a reply is usually quicker than typing it. Sayburst is a Mac app that puts dictation on a key: click into the reply, hold fn, talk, let go, and the text lands at your cursor. Speech recognition runs on your Mac, so your audio never leaves it.

The part that matters for email is per-app writing modes. Set Mail, Spark, Mimestream or Outlook to Email mode once, and every dictation in that app comes out shaped like an email. Here's a reply to a landlord, said the way you'd actually say it:

"hi marcus thanks for getting back to me so quickly um the plumber can come on thursday morning actually no friday morning is better because I'm out thursday and uh can you leave the key with the concierge thanks priya"

With Sayburst Writer, the optional AI model that runs on your Mac, this is what goes into the reply window:

Hi Marcus,

Thanks for getting back to me so quickly. The plumber can come on Friday morning, since I'm out on Thursday. Could you leave the key with the concierge?

Thanks, Priya

The "um" and "uh" are gone, "Thursday, actually no, Friday" became Friday, and the greeting, paragraph and sign-off are in place. Set Slack to Message mode and the same key gives you casual one-liners there instead.

A few details that help in mail apps specifically:

• Replacements turn "my email" or "my booking link" into the real thing.
• Vocabulary gets client and colleague names right.
• Rewrite selection: select a draft you typed, hold the rewrite shortcut and say "make this more polite", and the selection is replaced.
• Nothing gets lost. If you click out of the compose window mid-sentence, Sayburst keeps the text and ⌃⌥⌘V pastes it wherever you are. More in never lose a dictation.

Sayburst is $29 once for one Mac after a 7-day free trial, with no subscription, and needs an Apple silicon Mac on macOS 14 or later. It's Mac-only; on Windows, use the built-in voice typing (Windows key + H). For a step-by-step setup, see how to dictate email on Mac, or the Gmail guide if you write in Gmail in the browser.

#Which one should you pick?

Ask yourself three questions.

Is all your mail in Gmail? Mimestream gives you the best Gmail experience on a Mac. If you need Gmail on Windows too, Spark or Superhuman.

Does work run on Microsoft 365? Use Outlook for that account. Many people keep Apple Mail for personal mail alongside it.

Do you want to pay at all? Apple Mail, Thunderbird, Outlook's free tier, and the free plans of Spark and Canary cover almost everyone. Pay when a specific feature, like Gatekeeper, PGP or Gmail-native labels, is worth it to you every day.

Whichever client you choose, the writing is still the slow part. Comparing dictation tools rather than mail apps? See the best dictation apps for Mac.
