The short version: Facebook Marketplace messages go missing because of filtered message requests, app sync bugs, buy-and-sell integrity blocks, or you simply being logged into the wrong Facebook profile or Page. Work through the five checks below in order and you will almost always find the missing conversation sitting in a folder you didn't know existed.
I have spent a lot of time inside the guts of Facebook over the years, including a full rundown of every Facebook fix and setting in one place, and Marketplace messaging is one of the most complained-about bits of the entire platform. Not because it is mysterious, but because Facebook buries the actual explanation and leaves you guessing.
Check your message requests folder first
This fixes it for most people, so start here. Facebook splits Marketplace messages into two buckets: your main inbox and "message requests." If someone messaging you about a sofa isn't already a friend, or hasn't messaged you before, their message gets filtered into requests automatically, often with zero notification.
- Open Messenger (app or desktop, messenger.com)
- Tap or click the inbox icon, top right
- Look for "Message requests" or "Spam" subfolders
- On the app, there's often a second filter called "Filtered requests" buried one tap deeper than the main requests tab
Say you run an online shop clearing out old stock through Marketplace. You post 14 items over a weekend. By Monday you have three sales confirmed and, you assume, no other interest. Check the filtered requests folder and you find six more messages from people asking if items are still available. Facebook never pushed a notification for any of them. That's not a rare glitch, that's standard behaviour for anyone who isn't friends with the buyer.
The app and the website don't always sync
Marketplace messages can show up in the Facebook app but not Messenger, or vice versa, because the two apps sometimes pull from different caches. If you're seeing "no messages" on one device, check on another before assuming the conversation is gone.
- Log into facebook.com/messages/marketplace on a desktop browser
- Check the dedicated Marketplace inbox inside the Facebook app itself (not Messenger), accessed via the Marketplace tab, then the chat bubble icon top right
- Force-close and reopen the app, or clear the app's cache in phone settings
- Update the app; Facebook pushes messaging bug fixes more often than almost any other feature, sometimes two or three updates a month
If a message shows on one platform and not another, that's a sync delay, not a deleted conversation. Give it up to 24 hours before you panic.
Facebook's buy-and-sell integrity system might be blocking it
This is the part most guides skip, and it's the uncomfortable bit: Facebook actively hides or throttles Marketplace messages it flags as risky, and it does this without telling you. If a buyer's account is new, has no profile photo, no mutual friends, or was recently created, Facebook can quietly restrict the conversation, sometimes blocking it from reaching your main inbox at all. This isn't a bug, it's a deliberate fraud and spam filter, and it's aggressive enough that it regularly catches genuine buyers too.
If you're a seller and messages have gone quiet right after you post a high-value item (anything over roughly £300 to £500 tends to trigger more scrutiny), check your Support Inbox under Marketplace settings. That's where restricted conversations sometimes land instead of your normal inbox.
You might be logged into the wrong identity
Facebook lets you run Marketplace through your personal profile, a Page, or a linked business account, and each of these has a separate inbox. If you listed an item while switched to a Page profile and then checked messages from your personal profile, you will see nothing, because you're looking in the wrong place entirely.
This trips up small business owners constantly. If you sell through both a personal profile and a Facebook group tied to your shop, double check which identity made the listing before assuming messages vanished. The same logic applies if you're active in Marketplace groups to sell more, since group listings can route messages differently depending on how the group is set up.

Notification settings are quietly switched off
Separate from the messages existing at all, Facebook's notification settings for Marketplace are opt-in in some regions and can get reset after app updates. Go to Settings, then Notifications, then Marketplace, and check that "Messages" is toggled on. If it's off, the messages are sitting in your inbox the whole time, you just never got told they arrived.
A step-by-step order to work through
- Check Messenger's message requests and filtered requests folders
- Check the Facebook app's own Marketplace inbox, separate from Messenger
- Check facebook.com on desktop
- Check your Support Inbox for flagged or restricted conversations
- Confirm which profile or Page the listing was posted from
- Check notification settings under Settings, Notifications, Marketplace
- Update the app and restart your phone
By the time you've worked through all seven, you have covered every realistic cause. If messages are still missing after that, it's worth reporting the specific listing through Facebook's Help Centre rather than general feedback, because Marketplace-specific reports route to a different support queue.
Why this keeps happening
Facebook's own priority with Marketplace messaging isn't you finding every message, it's keeping scam and spam volume down, and the tradeoff is that real conversations get swept up in that filtering too. That's a deliberate design decision, not an oversight, and no amount of settings-tweaking removes it completely. If you sell regularly, build the habit of checking all three inbox locations (main, requests, support) every few days rather than trusting a notification to tell you something arrived.
If you're managing Marketplace alongside a business Page or group, it's also worth reviewing how your pages and groups are connected; a poorly linked setup is one of the quieter reasons messages land somewhere unexpected, and our guide on how to link related Facebook groups together covers how that structure affects things like messaging and notifications.
Frequently asked questions
Why can't I see any messages on Facebook Marketplace at all?
Check your message requests folder in Messenger first, since unfamiliar buyers get filtered there automatically with no notification, then check the separate Marketplace inbox inside the Facebook app itself rather than only Messenger.
Does Facebook hide Marketplace messages from certain buyers?
Yes. Facebook's fraud and spam filtering can quietly restrict conversations from new or low-activity accounts, sometimes routing them to a Support Inbox instead of your main inbox, without any alert to you.
Why do messages show on the app but not on the website?
The Facebook app and facebook.com sometimes pull from different sync caches, causing a short delay between the two. Give it up to 24 hours, and try clearing the app cache or logging in on desktop to confirm.
How do I fix missing Marketplace notifications?
Go to Settings, then Notifications, then Marketplace, and check that Messages is switched on, since this toggle can reset after app updates and silently stop alerts even when the messages themselves are still arriving.
