Engage
Social Media Inbox: Comments, DMs and Mentions in One Place
Updated · Multi Post Social guide

A social media inbox gathers every comment, direct message, mention and review from every connected channel into one list you can work through top to bottom. In Multi Post Social the Engage module adds filters, labels, saved replies, AI reply suggestions, a score that surfaces what matters, and, on team plans, assignments and routing. This guide explains the screen, what each network lets a tool read and answer, and a ten-minute daily habit that keeps the inbox at zero.
What a social media inbox is, and why it changes results
Replies are the half of social media that most tools ignore. A post is a few minutes of work; the conversation under it can run for days across five apps, each with its own notification sound. A social media inbox turns those five apps into one queue. Each item carries the channel, the author, the text, the post it belongs to and a status: open, done or archived. You answer in place, the reply goes to the network, and the item moves to done.
The effect on results is larger than it sounds. Most networks lift the reach of posts that earn quick replies, because a reply is an engagement and a signal that the post started a conversation. Customers who get an answer in an hour buy more often than customers who get one in a day. And a team that sees every comment in one place stops missing the one complaint that would have grown into a thread. The inbox is where the scheduler earns its keep.

The inbox layout
The social media inbox screen has three columns on a desktop and three stacked views on a phone. The left column lists channels and saved filters with unread counts. The middle column is the item list, newest first by default, with the author, the first lines of text, the channel chip, labels and the score. The right column shows the selected conversation: the original post excerpt, the full comment or message, earlier replies, and the reply box with saved replies and the AI suggestion underneath.
Keyboard shortcuts move you through the list without the mouse: J and K to move, R to reply, E to mark done, L to label, A to assign. Mark done sends the item to the Done view, where it stays searchable. Archive hides an item that needs no answer, for example a mention in a list of twenty accounts. Nothing is deleted from the network; the inbox only changes how you see it.
Filters, labels and the comment score
Filters narrow the list by channel, type (comment, message, mention, review), status, label, assignee, sentiment and date. Save a filter and it appears in the left column with its own count, for example Open questions on Instagram or Negative, unassigned. Labels are free text you define once per workspace: Question, Support, Lead, Praise, Spam. Apply one with the L key or let a rule apply it, for example label Support when the text contains "not working" or "refund".
The comment score is a small number from one to five next to each item. It rises for questions, for words that signal a problem, for authors with many followers, for direct messages over public comments, and for items that have waited long. Sort by score and the list puts the customer with a broken order above the row of heart emojis. The score is a hint, not a rule; you can always sort by time.
Sentiment is shown as a small colored dot: positive, neutral or negative. It is estimated from the text and is right most of the time, which is enough to find the complaints quickly. The same sentiment model powers social media listening, so the two screens agree.
Replying, saved replies and AI suggestions
The reply box sends through the same token that publishes your posts. Public comments get public replies; direct messages get private ones; mentions get a reply on the network where they happened. You can attach an image or a GIF where the network allows it, and you can reply privately to a public comment on networks that support it, which is the polite way to handle an order problem in public.
Saved replies
Saved replies are answers you give often: shipping times, where to find pricing, a thank-you. Give each a short title, type the first letters in the reply box, pick it, then adjust a word or two so it does not read like a template. Saved replies can include placeholders for the author's name and the channel. The free plan includes one saved reply; paid plans have no limit.
AI suggestions
Under the reply box, the AI assistant drafts a reply that fits the comment and your tone profile. It understands the original post, so a question about the third tip in a carousel gets an answer about the third tip. You press Use, edit, and send. It never sends by itself and it never replies to a stranger without you, which keeps you inside every network's rules. Free plans get five suggestions a week; paid plans have no limit.
Turn a comment into a post
A great question or a kind review is content. Press Create post from a comment and the composer opens with the comment quoted, the author credited, and your reply as the caption draft. Ask permission for private messages; public comments are fine to quote with credit on most networks.
| Habit | Target | How the inbox helps |
|---|---|---|
| Two fixed check-ins a day | Median reply under 4 hours | Score sort and unread counts make each session short |
| Hourly glance on launch days | Median reply under 1 hour | Push notifications for questions and negative sentiment |
| Weekly cleanup | Zero open items older than 7 days | Filter: Open, older than 7 days; archive what needs no answer |
| Support hand-off | Support label answered within a day | Assign to a teammate; saved reply with the support address |
| Praise loop | Thank every positive mention | Sentiment filter plus a thank-you saved reply |
Assignments, routing and notes
On the Team and Agency plans, every item can be assigned to a teammate. The assignee sees it in their My items view and gets a notification. Routing rules assign automatically: Support label to the support person, Spanish text to the Spanish speaker, all items from the client's channel to the client's account manager. Internal notes sit under the conversation and are never sent to the network, so a teammate can write "customer called, resolved" where the next person will see it.
Inbox analytics show items received, answered and median response time per channel and per teammate, and feed the community section of your reports in analytics. Agencies use the per-client view to show response times in monthly reports. The team collaboration guide covers roles: viewers can read the inbox, contributors can draft replies for approval, editors and admins can send.

What each network shares with a social media inbox
Networks decide what a tool may read and answer. Most share comments on your own posts and mentions of your handle; fewer share direct messages; only some share reviews. The table shows current support. When a network does not share an item type, the inbox says so instead of showing an empty list.
| Network | Comments | Direct messages | Mentions | Reviews | Notes |
|---|---|---|---|---|---|
| Yes, with private reply | Yes (Business accounts) | Yes, in captions and comments | No | Story replies arrive as messages | |
| Yes, with private reply | Yes (Pages) | Yes | Yes (Page recommendations) | Group comments are not shared | |
| TikTok | Yes | No | No | No | Comment replies only |
| Yes (Pages and profiles) | No | Yes (Pages) | No | Reactions shown as counts | |
| X | Yes (replies) | Yes | Yes | No | Quote posts appear as mentions |
| YouTube | Yes | No | No | No | Comments can be hearted and pinned |
| Threads | Yes (replies) | No | Yes | No | Reply controls set per post |
| Yes | No | No | No | Pin comments only | |
| Google Business Profile | No | No | No | Yes, with replies | Review replies are public |
| Bluesky | Yes (replies) | No | Yes | No | Quote posts appear as mentions |
| Mastodon | Yes (replies) | Yes (direct posts) | Yes | No | Visibility follows the post |
| Substack | Yes (Note replies) | No | Yes | No | Restacks shown as mentions |
Step by step: a ten-minute inbox habit
- Open the inbox at a fixed time, twice a day. Set a reminder in the mobile app if it helps.
- Sort by score. Answer the top items first: questions, problems, big accounts.
- Use the AI suggestion as a start, edit one phrase so it sounds like you, send.
- Label as you go. Support, Lead, Praise. Thirty days later the labels tell you what people really ask.
- Hand off what you cannot solve. Assign to a teammate or send the support saved reply with the address.
- Thank the praise. Filter positive, send the thank-you, mark done.
- Archive the noise. Mentions in giveaway lists, emoji-only comments you do not want to answer.
- Turn one comment into a post once a week. Questions are the best content briefs you will get.
Mistakes that make a social media inbox pile up
A social media inbox at zero is a habit, not a feature. These are the patterns that let the list grow until it feels hopeless, and the small change that keeps it short.
Checking when a notification arrives
Reacting to every ping means you are in the inbox all day and never done with it. Turn off most push notifications, keep the ones for questions and negative sentiment, and open the social media inbox at two fixed times. Batching replies is faster, and the median response time still lands under a few hours.
Reading newest first
Newest first rewards the latest heart emoji and buries the complaint from this morning. Sort by score, or by oldest open item, so the people who waited longest and the people with a problem are answered first. Set score sort as your default and the list orders itself.
Answering the same question by hand
If you have typed where to find pricing four times, you need a saved reply. Build them from the questions you see in a week, give each a short title, and edit one word before sending so the reply still sounds human. A social media inbox with ten good saved replies runs twice as fast.
Leaving noise open
Mentions in giveaway lists, emoji-only comments and spam do not need an answer, but every open item costs attention. Archive them in one pass with a filter, or add a rule that archives items matching a pattern. The Done and Archived views keep everything searchable, so nothing is lost.
No owner for hard items
An item that nobody owns is an item that waits. On team plans, assign every item that needs more than a quick reply, and route Support and Lead labels to the right person automatically. On a single-user plan, label it and set a fixed time to clear the labeled items. The team collaboration guide shows how roles keep the reply button in the right hands.
Arguing in public
A public reply is read by far more people than the person you answer. Move problems to a private message, keep the public note short and kind, and do not feed trolls; archive and report them on the network. The social media inbox gives you a private reply button on the networks that allow it for exactly this reason.
Never looking back
Labels and response times are data. Once a month, open the inbox analytics: which labels grew, which channel waits longest, which saved reply is used most. A rising Support label is a product signal; a slow channel is a staffing signal. The analytics guide explains how the community section fits in a monthly report.
Benefits and limits
The benefits of a social media inbox are fewer missed conversations, faster replies and a record. One list beats five apps; the score beats scrolling; labels and notes beat memory. Teams gain fair workloads through assignment and a response-time number they can improve. Agencies gain a per-client inbox and a line in the monthly report that clients notice.
The limits come from the networks. Some do not share messages; some do not share reviews; a few share comments only on posts published through the tool. Sentiment and score are estimates. And a social media inbox makes replying easier, not automatic: the tone, the speed and the decision to answer stay with you. Automatic replies are not offered, because they break network rules and they sound like what they are.
The inbox on your phone
The mobile app opens on the social media inbox list with swipe actions: swipe right to mark done, swipe left to assign or label. The reply box supports saved replies and the AI suggestion, and voice dictation works like in any text field. Push notifications can be limited to questions, negative sentiment and direct messages so the phone stays quiet for hearts. Images in replies come from the camera roll. Tips: turn on the score sort as default on the phone, and use the Done view at night to see what the team answered.

Safe use and tone in public replies
Every reply is public or private exactly as the network decides, and public replies are read by far more people than the person you answer. Keep the tone you would use in person, move order and account problems to private messages or email, never share personal data in a public reply, and do not argue with trolls; archive and, if needed, report them on the network. Automatic replies to strangers break network rules and are not offered. Replies are sent with the channel token, so review connected apps and keep two-factor authentication on in security settings. Each network publishes its own community rules, for example TikTok for Business help and the Meta Business Help Center.
Frequently Asked Questions
Which messages appear in the social media inbox?
Comments on your posts, direct messages, mentions of your handle and reviews, for the networks that share each type with tools. Instagram and Facebook share all four; TikTok, YouTube and Pinterest share comments only; Google Business Profile shares reviews. The table on this page has the full list.
Does the social media inbox reply automatically?
No. The AI drafts a suggestion and saved replies fill the box, but you press Send. Automatic replies to strangers break most networks’ rules and are not offered.
Can I reply privately to a public comment?
On Instagram and Facebook, yes: choose Reply privately and the answer goes as a message while the public comment can get a short public note. Other networks keep public and private channels separate.
How do assignments and routing work?
On Team and Agency plans each item can be assigned to a teammate by hand or by rule, for example by label, language or channel. Assignees see their items in My items and receive notifications. Internal notes are never sent to the network.
What is the comment score?
A one-to-five hint that rises for questions, problem words, large accounts, direct messages and waiting time. Sort by score to answer what matters first. You can always sort by time instead.
Are comments from before I connected a channel imported?
Recent comments on recent posts are imported where the network allows, usually the last 30 days. Older items stay on the network.
Can clients see their inbox?
Agency plans give each client workspace its own inbox. Clients with a viewer role can read it; editors and admins can reply. Response times per client appear in white-label reports.
