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.
Importance labels are account-wide, not per-inbox. If you connect multiple Gmail accounts, your label set is shared across all of them — the same labels classify every inbox, and a custom label with a from: filter catches that sender no matter which account it lands in. (This is different from native Gmail labels, which stay separate per Google account.)

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.

You can also create and refine labels directly from the agent sidebar. Ask “Create a label for anything related to the Acme renewal” or “Make the Newsletter label stricter, it’s catching too many sales emails” and the agent sets up or updates the label for you. The change is surfaced immediately in your tab bar, no need to open Settings.

​
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.
