Facebook Marketplace Auto Reply Guide

Your complete guide to automating Facebook Marketplace conversations with AI-powered responses

GetReplyNow Guide

GetReplyNow automates your Facebook Marketplace replies with AI. This guide walks through each part of the dashboard. New here? The fastest way to get going is the Quick Start.

How it works

  1. Set up your AI once in Settings — your business info and how you want it to reply.
  2. Install the Chrome extension — it watches your Facebook Marketplace inbox.
  3. Go live — the extension replies to buyers automatically, using your settings.

Optionally, give each product its own description so replies are listing-specific.

Sync your FB Marketplace listings

You don't have to import listings to go live — your AI can reply from your shared Business Info. Import them when you want listing-specific answers (recommended if you sell different products).

Auto-fetch with the Chrome extension

  1. Open the GetReplyNow extension
  2. Go to facebook.com/marketplace/you/selling — your active listings page
  3. Click "Import Listings" in the extension
  4. Done — your listings are imported with their descriptions

Fetch listings from Facebook Marketplace

When a buyer messages you, GetReplyNow finds the right listing:

  1. Searches for matches — looks for your listing title inside the buyer's message
  2. Ignores case and accents — "iPhone 12" matches "iphone 12"
  3. Picks the most specific match — "iPhone 12 Pro Max" wins over "iPhone"
  4. Partial matching — the buyer doesn't need to type the exact title

Settings

Settings is where you control how the AI replies. It has two tabs — and here's the key idea:

Both tabs have the same tools — Description, AI Assistant instructions, Smart Conditions, and Follow-ups. The only difference is scope:

  • All listings applies to every listing. Its description is your shared business info.
  • Each listing applies to one product. Its description is that product's details.

So "Each listing" mirrors "All listings" — same controls, just for a single product. The two stack: your All listings settings always apply, and Each listing adds product-specific detail on top — it never replaces or overrides them.

each_listings

All listings — shared across every listing

🏢 Business info

Shared detail about your business — name, hours, location, payment, pickup, policies. Auto-fill from Google, use a template, or type it. Optional — skip it if you sell as an individual.

🤖 AI Assistant

How the AI talks and what it does on every listing — for example, always ask for a phone number, book a call, or point buyers to your site. Smart Conditions also live here: situation-specific rules (first message, price questions, high-intent buyers) applied across all listings. Optional and free on the free plan.

📨 Follow-ups

Default follow-up nudges for any listing that doesn't set its own. See the Follow-Ups section below.

⚙️ App Limits & Controls

  • Disable the Chatbot — instantly pause all replies
  • Scan for Missed Messages — reply to chats you missed while offline (see Advanced below)
  • Chat Limit per Buyer — stop the AI after a set number of messages so a human can step in
  • Data Link (Webhook) — send your data to Zapier, Make, or n8n

Each listing — a unique reply per product

Open any listing to give it its own description, AI instructions, Smart Conditions, and follow-ups — these stack on top of your shared settings, they don't replace them. The main difference is the description field: under All listings it's your shared business info; here it's that one product's details. Both are sent to the AI together.

This is what lets the chatbot answer accurately about each specific product, instead of giving the same reply to everyone.

There's also a "Use my shared Business & AI settings for every listing" toggle:

  • Off (default): the AI matches each listing and uses your business info with its own description
  • On: the AI replies from your shared settings only — best if you sell one product (see Advanced below)

Follow-Ups

Most buyers go quiet after a message or two. Follow-Ups send a short nudge after a delay you choose, so those conversations don't die.

  1. Open Follow-ups (in Settings, or from the sidebar)
  2. Add one or more delays (e.g. 24 hours, 3 days)
  3. Write a short message for each — a sentence or two is plenty
  4. Save — the bot handles them automatically

Good to know:

  • A follow-up only sends if the buyer has gone silent since your last reply
  • The moment they respond, the chain stops for that conversation
  • You can chain delays (24h → 3 days → 7 days), each with its own message

"Hey — just checking in, is this still something you're interested in? Happy to answer any questions."

💡 Keep them friendly and low-pressure. ⚠️ Don't stack too many — one or two captures most of the value; more starts to feel like harassment and risks Facebook flagging your account.

Inbox

The Inbox is your Facebook Marketplace inbox inside GetReplyNow — every conversation, alongside the replies your chatbot has sent. Use it to monitor how the AI handles real buyers.

Chat Playground

Test your replies before going live. Pick a listing, play the buyer, and see exactly how the AI responds. Nothing is sent to Facebook — it's a safe sandbox.

Chat Playground

💡 Use it to fine-tune your Business Info and AI Assistant until replies sound like you.

Advanced

Scan for Missed Messages

Normally the bot only replies to conversations with a blue dot (unread). Turn this on and, at startup, it also scans a set number of recent conversations and replies to any that match your rules — even ones you'd already opened. Then it switches back to normal blue-dot detection.

  • Set how many recent conversations to scan (e.g. 20) in Settings → App Limits & Controls
  • Scanning happens only at startup
  • ✅ Best for: chats you opened but forgot to reply to, or busy high-volume periods

💡 Start with 20; increase only if you regularly miss chats.

Shared Settings Mode

Turning "Use my shared Business & AI settings for every listing" ON makes the bot reply to every message without matching a specific listing — using only your shared Business Info & AI Assistant.

  • ✅ Best for: single-product sellers, service providers, or capturing every lead
  • ⚠️ It will also reply to non-Marketplace messages (page DMs, comment triggers), which can cause awkward auto-replies to personal chats
  • 💡 When it's on, your shared Business Info & AI Assistant are the only source for replies — make them comprehensive but versatile
