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.
