Worth knowing

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.

Shortwave

  • Sign-in requires Gmail or Google Workspace. Microsoft 365 and Exchange are not supported, and other providers only work by forwarding mail to Gmail.
  • Paid plans start at $18 per seat a month for individuals and $30 on the business plans, and AI usage on every plan is capped by a daily quota.
  • The Business plan limits AI search to 5 years of history and allows 3 AI filters.
  • Native apps cover Mac, Windows, iOS and Android; other platforms rely on the web app.

Key features

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.

Shortwave

AI assistant
Prompt the assistant to organize the inbox, write in your own voice, search mail or schedule a meeting. It can also browse the web and analyze attachments.
AI filters
Describe a rule in plain English and it labels, stars or archives incoming mail. Business includes 3 AI filters, Premier 10 and Max 50.
Split inbox and bundles
Divide the inbox into tabs by sender, label or custom query, and triage promotions, newsletters and updates in bulk as bundles.
AI search
Ask questions across your mail instead of keyword searching. Business reaches back 5 years and reads up to 50 threads per search; Premier removes the history limit.
Team collaboration
Share a live thread with teammates, discuss it in private comments, assign emails with a done status, and keep shared labels, snippets and saved prompts.
Scheduling and follow-ups
The assistant checks availability, creates calendar events and writes scheduling emails. Snooze, delivery schedules and no-reply reminders are also included.
