Mimestream

• The Pro plan, listing priority support, custom domains, team collaboration and API access, is marked Coming Soon with no price.

Mimestream

• Mac only: it requires macOS 12 Monterey or newer, and the site lists no iOS, Windows or web version.
• Built for Gmail accounts; the site does not mention support for other email providers.
• Subscription only, with no one-time purchase, and an active subscription is required to keep using the app.
• A license covers up to 5 devices, and monthly plans are not refundable.

Marco

One inbox for every account

Connects Gmail, Outlook, Yahoo Mail, iCloud Mail and any provider that supports IMAP, with no limit on the number of accounts managed from a single inbox.

Offline-first

Emails are synced to the device, so you can read, search, compose and organize without an internet connection. Changes sync automatically once you reconnect.

No AI writing

Marco does not generate, rewrite, summarize or reply to email with AI. The company presents this as a deliberate choice to keep email a conversation between people.

Privacy

No ads, tracking or scanning of email for advertising. The site says data is encrypted at rest and in transit and that the company has no access to email content.

Native Apple apps and a web version

Native apps for Mac, iPhone and iPad with keyboard shortcuts, plus a web version for any modern browser, with sync across devices.

Search, labels and filters

Smart search, custom labels and filters, and views that narrow the inbox by account, label or sender.

Mimestream

Gmail features in a Mac app

Powered by the Gmail API, so inbox categories, color-coded labels and Gmail-backed search behave the way they do in Gmail.

Server-side filters and vacation replies

Create and edit Gmail filters and vacation responses from inside the app instead of going to Gmail's web settings.

Multiple accounts and unified inbox

Add all of your Gmail accounts, combine them in an optional unified inbox and send from any configured Gmail alias.

Tracking prevention

Blocks email trackers from more than 75 common services.

Templates, snooze and undo send

Pre-written templates with variables, snoozing a message to return later, send and archive in one step, and reopening a draft after sending.

macOS integration

Dark mode, keyboard shortcuts, system notifications, swipe gestures, a menu bar extra, image markup and Apple silicon optimization.
