It does. You can use the forwardmessage tool to pass an email to another address. You can even include custom text to add context before the message leaves your inbox.

Manage email threads in Windsurf

Cascade reads your inbox directly to pull conversation threads. Use `list_threads` to find active subjects and `get_thread` to read the full history of a specific conversation. Once the agent has the context, it uses `reply_to_message` to keep the thread alive. You don't have to switch tabs to keep a conversation moving.

Automate inbox organization

You can spin up new addresses on the fly using `create_inbox`. Connect these to custom domains to keep your agent-specific communications separate from your personal mail. If a project ends, use `delete_inbox` to wipe the slate clean. This clears out all stored messages associated with that ID immediately.

Handle attachments autonomously

When an email comes in with files, Cascade identifies them through the metadata. It calls `get_attachment` to pull the raw data into your current workspace. Parsing the base64 content happens right in the editor. Your agent handles the heavy lifting so you can focus on the code.
