Unanswered Message Chaser

Example prompt: "Check my sent Gmail every morning for emails I marked as important that haven't received a reply in 48 hours. Send me a Slack reminder with the subject, recipient, and how long it's been waiting."

The Problem

Important emails go unanswered all the time — not out of malice, but because inboxes are busy and messages slip through the cracks. Manually keeping track of which emails need a follow-up means maintaining a mental list or a spreadsheet of sent messages and their expected reply dates. Most people simply forget, and opportunities or decisions stall because nobody chased the response.

How GloriaMundo Solves It

We build a scheduled workflow that runs each morning and checks your sent email for important messages that have not received a reply within your chosen timeframe. An integration step fetches your recent sent emails filtered by a label or flag you apply when sending something that needs a response. A code step cross-references each sent message against your inbox to check whether a reply has arrived. For any message still unanswered past the threshold, the workflow sends you a Slack reminder listing the recipient, subject, date sent, and how many days it has been waiting. You can then decide whether to send a follow-up or let it go. Glass Box preview shows you which messages would trigger reminders before the workflow runs live.

Example Workflow Steps

  1. Trigger (scheduled): Runs every weekday morning at 9:00 AM.
  2. Step 1 (integration): Fetch sent Gmail messages from the past 7 days that carry the "needs-reply" label.
  3. Step 2 (integration): For each sent message, search the inbox for replies from the same recipient and matching thread.
  4. Step 3 (code): Compare sent timestamps against replies. Flag any message that has been unanswered for more than 48 hours.
  5. Step 4 (conditional): If no messages are overdue, end the workflow. Otherwise, proceed to the reminder step.
  6. Step 5 (integration): Send a Slack message listing each unanswered email with the recipient name, subject line, and number of days waiting.

Integrations Used

  • Gmail — source of sent messages and inbox replies for cross-referencing
  • Slack — delivery channel for follow-up reminders

Who This Is For

Sales professionals, account managers, and anyone whose work depends on timely replies — people who send 10-20 important emails a day and cannot afford to let follow-ups slip through the cracks.

Time & Cost Saved

Manually reviewing sent emails and tracking which ones need follow-up takes 10-15 minutes a day. This workflow automates the tracking entirely and only surfaces the messages that actually need your attention. Over a working week, that is roughly an hour saved, plus the harder-to-quantify value of deals and decisions that do not stall. The workflow uses integration and code steps with minimal LLM cost.
