Build FAQ From Inbox Emails
Scans your recent Gmail inbox weekly, extracts audience questions, generates on-brand answers, and posts a formatted FAQ document to Slack.
What This Workflow Does
This workflow turns your inbox into a self-updating FAQ. Every week, it scans your recent emails, pulls out the questions your audience keeps asking, generates clear answers, and drops a nicely formatted FAQ into your Slack channel.
It's built for solo creators, newsletter writers, podcasters, and course creators who get the same questions over and over but don't have time to maintain an FAQ page manually.
At a high level, the workflow performs five steps:
- Runs on a weekly schedule (every Monday at 9 AM ET)
- Pulls your recent emails from Gmail
- Extracts and categorizes audience questions using AI
- Generates friendly, on-brand answers for each question
- Formats and posts the full FAQ to a Slack channel
What You Need
- A Gmail account connected to Needle (this is the inbox where your audience reaches you)
- A Slack workspace connected to Needle (where you want the FAQ posted)
- No API keys or additional setup required
How the Flow Works
| Step | Node | What It Does |
|---|---|---|
| 1 | Scheduled Trigger | Kicks off the workflow every Monday at 9 AM Eastern. You can adjust the schedule to daily or biweekly depending on your email volume. |
| 2 | Gmail Find Email | Searches your inbox for emails received in the last 7 days. It pulls up to 50 emails and converts them to a text format that the AI nodes can work with. |
| 3 | Extract Questions (AI Agent) | Reads through all the emails and identifies real questions your audience is asking. It cleans them up, removes duplicates, and organizes them into categories like "pricing," "getting started," "technical," "content," and "general." |
| 4 | Generate Answers (AI Agent) | Takes each extracted question and writes a concise, friendly answer in the voice of an approachable solo creator. Answers are 2–4 sentences long. If the AI doesn't have enough context for a perfect answer, it flags it so you can customize later. |
| 5 | Build FAQ Document (AI Agent) | Formats everything into a clean Slack message. Questions are grouped by category with clear Q&A formatting, a date stamp, and a footer noting it was auto-generated. |
| 6 | Send to Slack | Posts the final FAQ document to your chosen Slack channel so you can review it, copy it to your website, or share it with your community. |
Output
Every Monday, you get a fully formatted FAQ document posted to Slack. It includes categorized questions and answers pulled directly from what your audience actually asked that week. You can copy this into your website, newsletter, Notion wiki, or anywhere else you keep your public FAQ.
Customization Tips
- Time range — The workflow searches emails from the last 7 days by default. You can change the Gmail search query to cover a different time range or filter by specific labels.
- Slack channel — If you want to target a specific Slack channel, update the Slack node with your preferred channel name.
- Email quality — For best results, make sure your Gmail inbox has real audience emails. The AI works best when there are actual questions to extract rather than just newsletters or notifications.
- Alternative destinations — You can swap the Slack output for Google Docs, Notion, or any other destination if Slack isn't where you want the FAQ to land.
