Slashy uses AI to classify every incoming email into an importance label. Instead of one giant inbox, your email is sorted into focused tabs like Important, Calendar, Billing, and Newsletter. You control which labels exist, what they mean, and how each one behaves.

How Classification Works

When a new email arrives, the AI reads message content, sender info, and your contact history to assign a label. It considers:
  • Sender identity — real person vs. automated notification
  • Message content — does it require a response?
  • Thread history — part of an ongoing conversation?
  • Label descriptions — your instructions guide the AI
  • Deterministic filters — from:, to:, subject: rules bypass AI entirely
  • Training examples — your past corrections improve accuracy

​
Creating Custom Labels

Press n l from anywhere, or go to Settings > Labels > New Label. Provide a name, description (natural language instructions for the AI), and optional filters (from:, to:, subject: rules). Slashy can generate an AI-assisted description to improve accuracy.

​
Per-Label Behaviors

Each label has a Triggers Notification toggle. Enable it for labels that matter (Important, VIP Clients). Disable for quiet categories (Newsletter, Billing). Configure in Settings > Labels.
Disable Show in All Mail for a label to auto-archive its emails. They appear only when you navigate to that label tab.
Enable reminders per label. Set timing with natural language (e.g., “2 days”). Reminders auto-dismiss if you reply or archive before they fire.

​
Training the AI

When you reclassify a thread (using l or v, or drag-and-drop), Slashy asks why the classification was wrong. Your feedback becomes a training example that prevents the same mistake.

When creating or editing a label, Slashy shows a batch preview of matching emails. Approve or reject threads as training data before going live.
