Slashy is a new AI email app for Mac that positions itself around a single promise: you should rarely need to open your inbox. It learns from your existing emails and reply patterns to surface what matters and draft responses in your own tone, not a generic AI voice.
What It Does
With no manual setup, Slashy pulled contact info and contextual history for over 20 contacts from recent email threads during the reviewer’s first session. It also surfaced scheduling context, including office days, remote days, and an upcoming vacation, without being told any of it explicitly.
Draft quality stood out. The reviewer reported that Slashy’s suggested replies matched their own humor, tone, and phrasing closely enough that they initially thought they had already written the response themselves. Each draft comes with a prompt to adjust it, such as flipping a positive reply to a negative one or dialing the tone toward more professional.
Integrations
- Claude via MCP: Summarize threads or draft replies using Claude directly from a sidebar
- Notion: Read and write to Notion databases
- Slack: Connected workflow support
- iMessage: Listed as supported, though the reviewer noted it was not working on macOS Golden Gate beta at time of testing
Slashy also runs scheduling workflows automatically to help identify meeting availability.
Pricing and Availability
Slashy supports Gmail accounts now. Outlook support is listed as coming soon. Pricing is $30 per month or $300 per year for unlimited inboxes and AI usage.
Notion Mail shut down shortly after launch because its developer concluded that more users prefer agentic AI inbox management over opening the app at all. Slashy is built around exactly that premise from the start.
