Tools

Per-tool listings haven't synced yet for Mails.so. The connection itself works — your Space can already @-mention it. Tool descriptions will fill in on the next Composio ingest.

Setup

  1. Create or open a Switchy Space.
  2. Open Integrations and connect Mails.so.
  3. Authorise through api_key. Switchy stores the connection against your org.
  4. Everyone in the Space can now @-mention the Mails.so tools in chat.

What teammates see: by default, memories from Mails.so are scoped to the Space (PROJECT visibility) — you can mark any memory PRIVATE or share it ORG-wide.
