Glassmail vs Superhuman: which Mac email app is right for you?
Superhuman costs $25–40 a month and supports Gmail and Outlook. Glassmail is a one-time purchase for every account, with AI that runs on your Mac.
Short answer: pick Superhuman if you work in a team, need it on iPhone, Windows or the web, and are happy to pay $25–40 a month. Pick Glassmail if you’re one person on a Mac, have accounts beyond Gmail and Outlook (iCloud, Yahoo, Fastmail, a custom domain), want AI that doesn’t send your mail to the cloud, and would rather pay once.
Both are built around the keyboard and getting through email fast. They differ on price, privacy and which accounts they support.

Price: once vs every month
Superhuman Mail starts at $25 a month on a yearly plan, which is $300 a year. Over three years that’s $900 for one person. Glassmail is a single payment of $49 at most, for up to three Macs, with every 1.x update included.
If your company pays for Superhuman and you value its team features, the price may not matter. If you pay yourself, it’s the biggest difference between the two.
Accounts: everything vs Gmail and Outlook
Superhuman works with Google and Microsoft accounts and nothing else. If you also have iCloud mail, an old Yahoo address or a domain hosted somewhere else, you’ll need a second app.
Glassmail puts all of them in one inbox. Type your address and it finds the servers; Gmail, iCloud and Yahoo use an app password, and Microsoft accounts sign in with Microsoft.
AI: on your Mac vs in the cloud
Superhuman’s AI (writing, Ask AI, auto drafts) runs on cloud models, so your email is sent to process it. Glassmail’s assistant, thread summaries and writer run on your Mac, with Apple Intelligence on macOS 26 or a small Gemma or Qwen model you download on any Mac, Intel included. It works offline and there’s no AI fee. How private AI for email works.
Cloud models are bigger, so Superhuman’s AI can handle longer, more complex requests. Glassmail’s is built for the everyday jobs: “what needs me today?”, the gist of a long thread, and a reply in your voice.
Speed and triage
Superhuman is famous for speed and its “Superhuman command” palette. Glassmail has its own: ⌘K for everything, and Triage mode, which shows one conversation at a time with single keys to archive (E), snooze to tomorrow (H), reply (R) or skip (J). Both have snooze, send later, undo send and follow-up reminders.
Glassmail separates mail from people from updates and newsletters automatically, and shows sign-in codes in the list with a copy button. Superhuman uses split inboxes you can customise.
Privacy
Glassmail has no mail server: your Mac connects straight to your provider, and passwords live in the macOS Keychain. Superhuman syncs through its own service so it can work across devices and provide team features. Glassmail also strips tracking pixels; Superhuman offers read statuses, which rely on them.
Which should you choose?
- Choose Superhuman if you need iPhone, Windows or web access, work in a team that shares conversations, or your company pays.
- Choose Glassmail if you’re on a Mac, have more than Gmail and Outlook, want AI that stays on your Mac, and want to pay once.
Glassmail is free for 14 days with every feature, so you can try triage and the assistant on your real inbox before deciding. See also: the best Apple Mail alternatives and Superhuman alternatives without a subscription.
