# Track client reply SLAs in Gmail with OpenAI, Google Sheets, and Slack

> Quick overview This workflow runs hourly to find Gmail threads where a client is waiting for your reply, uses OpenAI to triage and summarize new overdue messages, logs SLA timing in Google Sheets, and posts new and escalated reminders to a Slack channel. How it works 1. Runs every hour on a schedule. 2. Reads recent Inbox and Sent messages from Gmail and matches them by thread to identify client emails that are still awaiting your reply. 3. Compares the currently-waiting threads against a Google Sheets “Reply Log” to detect newly-due threads, threads that have become overdue, and threads you have already replied to. 4. For newly-due or overdue unlogged threads, sends the email preview to OpenAI to decide whether a reply is needed, assign a priority, and generate a short summary. 5. Appends each new thread evaluation to the Google Sheets “Reply Log” and posts a formatted alert to Slack only when OpenAI indicates a reply is needed. 6. For still-unanswered threads that cross 2× the reply
