What problem does it solve? When your cold email campaigns mix Gmail, Office365, and SMTP inboxes, it is hard to tell which inbox type is actually delivering and which is dragging down results. This Skill aggregates per-inbox campaign stats from the Smartlead API and breaks down reply rates and bounce rates by inbox type so you can spot underperforming segments. ## Core Features & Use Cases - Inbox Type Comparison: Groups all email accounts by type (G Suite/Gmail, Office365/Outlook, SMTP) and compares sent, replies, bounces, reply %, and bounce % in a formatted table. - Flexible Scoping: Supports optional client ID filtering for sub-accounts and configurable lookback windows (default 7 days). - Automated Takeaways: Highlights the best and worst performing inbox types and flags types with elevated bounce rates for further audit. - Use Case: You run 80 inboxes across three providers and notice overall reply rates dropping. Run the comparison to discover your SMTP inboxes bounce at twice the account average, then retire them and provision replacements. ## Quick Start Set the SMARTLEAD_API_KEY environment variable and ask the assistant to compare inbox type performance for the last 7 days using the Smartlead API.
