What problem does it solve? Managing hundreds of cold-email inboxes in Smartlead by hand is slow and error-prone: each inbox needs warmup enabled with the right ramp, a signature applied, tags for tracking active vs insurance status, and ongoing health monitoring. This Skill automates all of that through the Smartlead API. ## Core Features & Use Cases - Bulk warmup control: Enable warmup with a ramp (1/day growing by 5/day up to 40/day), disable it for active senders, or apply a low-volume maintenance mode for insurance inboxes. - Bulk signature setting: Apply a templated signature (name, title, company, physical address) across selected inboxes, with per-inbox persona support via the inbox's from_name field. - Tag management: Add or remove tags like active, insurance, or retired across inbox batches selected by ID, domain, tag, or CSV. - Health dashboard: Generate a CSV and console summary of warmup status, reputation, daily sends, and blocked inboxes, with action items. - Use Case: After provisioning 80 new inboxes, run the Day 1 workflow to enable warmup, set signatures, and tag them as insurance, then run a weekly health check to catch blocked or bad-reputation inboxes before they hurt campaigns. ## Quick Start Set the SMARTLEAD_API_KEY environment variable and ask the assistant to enable warmup with the standard ramp on all newly tagged inboxes, then apply signatures and tag them as insurance.
