Run cold outreach sequences directly inside Windsurf

The `list_campaigns` tool lets Cascade inspect your active outbound sequences through the MCP Server. Cascade reads your goals, spots low-performing setups, and uses `pause_campaign` to halt sequences that drop below your target reply rates. Once you clean up the targeting, the agent triggers `resume_campaign` to get your emails moving again. The editor handles the sequence adjustments without manual intervention.

Monitor sending health and scale inbox volume

The `list_accounts` tool gives your editor immediate access to every connected email sender account. Cascade reviews the health of these senders by running `get_account_stats` to catch high bounce rates before they burn your domains. If an inbox shows signs of deliverability decay, the agent adjusts the load across other active senders. This keeps your cold email pipeline healthy while keeping manual overhead at zero using this secure MCP setup.

Inject verified leads directly into active campaigns

The `add_leads` tool allows your agent to feed fresh prospects directly into your sequences. Cascade pulls lead data from your workspace, verifies the formatting, and pushes them into your chosen queue. To keep you from sending duplicate pitches, Cascade runs `list_leads` to verify who already exists in the campaign. This prevents spam complaints and keeps your sender reputation clean.
