You tap the red bell on Substack and the same pile opens: a like from last night, a restack you already celebrated, two replies that needed an answer before lunch, and a follower ping that feels important until you read it. That pile is the Substack activity feed. Most writers treat it like a badge. The ones who grow treat it like an inbox of signals that either become replies, Notes, or deliberate ignores.
TL;DR: The Substack activity feed (the bell / Activity section) collects likes, replies, mentions, restacks, new subscribers and followers, and some recommendations. Per Substack Help, you can engage from the tab, only you see the feed, and the Activity section cannot be cleared. Use the feed as a growth inbox: replies and mentions first, restacks and subscribers as distribution signals, likes last. For email and push settings, see How to Manage Substack Notifications. When the native feed gets too long to work through, WriteStack Activity Center filters to comments, mentions, and meaningful replies, adds keyboard shortcuts, and auto-clears handled items so the pass fits a short daily block.

What the Substack activity feed is
Substack's Help Center is direct: the bell on your account is the Activity section (What is the bell icon on Substack?, updated 16 Dec 2025; checked 28 Sep 2026). Writers also call it the Substack activity feed, the Activity tab, or simply "the bell."
Inside that feed you find:
- Likes and replies to comments you have made
- Likes and replies on Notes you have posted
- Mentions and restacks in Notes
- Notifications for new subscribers and followers
- Recommended publications from creators you subscribe to
You can like, reply, restack, or share a Note from the Activity tab. No one else sees your Activity items as a list, even when the underlying events are public on a publication.
For Notes specifically, Substack documents the same engagement channels under What notifications do I get about Substack Notes? (updated 16 Jun 2025; checked 28 Sep 2026): likes, replies and mentions, restacks, and a paid-subscription alert when a Note generates at least $100 ARR in new paid subscriptions. Those alerts can arrive by email, push, and the Activity section. Muting email or push does not empty the feed.
On the Substack app, push can be off while Activity still fills when you tap the bell (Getting started on the Substack app, checked 28 Sep 2026). The feed is the durable log. Alerts are optional noise around it.
Practical rule: name the job correctly. Settings control interruption. The Substack activity feed is the record of engagement. Growth work happens when you read that record on purpose.
If you came here looking for Engagement toggles, pause notifications on a Note, or Android push categories, open How to Manage Substack Notifications. That page covers the settings pass in depth. This page covers what the feed is and how to operate it.
Every item type and what it usually means
Treat each row as a signal with a default action. Substack documents what shows up in the feed (bell Help, 16 Dec 2025; Notes notifications Help, 16 Jun 2025). The signal and action columns are our own take.
| Item type | Growth signal | Default action |
|---|---|---|
| Reply on your Note or comment | Conversation debt; often highest intent | Answer same day when the question is real |
| Mention in a Note | Someone pulled you into their audience | Reply, restack thoughtfully, or thank and move on |
| Restack of your Note | Distribution; new eyes on old words | Skim who restacked; note which hooks travel |
| New subscriber | List growth | Log the spike; pair weekly with Notes that convert |
| New follower | Graph growth (separate from your email list) | Useful for reach; do not confuse with subscribers |
| Like on Note or comment | Encouragement | Rarely needs a reply; process last |
| Recommendation noise | Discovery from people you follow | Skip during creator triage |
| Paid Note alert ($100 ARR) | Monetization signal on a specific Note | Study that Note; write more like it |
Replies and mentions are where relationships compound. Restacks tell you which lines travel. Subscribers tell you which Notes (or posts) moved the list, which you can review in Which Notes Bring Subscribers and Substack Notes analytics. Likes keep the red badge alive without teaching you much about next week's writing.
Practical rule: if a pass spends ten minutes on likes and zero minutes on unanswered replies, you read the feed as vanity. Flip the order.
Start a 7-day WriteStack trial when you want the high-intent slice of this table without scrolling past every like first.
What you can and cannot clear
Writers search the Substack activity feed expecting an archive button. Substack's own Help draws a hard line.
Activity cannot be cleared. The bell article ends with: your Activity section cannot be cleared nor notifications disabled (updated 16 Dec 2025; checked 28 Sep 2026). You can stop alerting yourself. You cannot wipe the in-product pile the way you archive email.
Email and push are separate from the feed. Under Settings → Engagement you can mute Replies, Likes, Restacks, and Mentions for Email and/or Push (How do I disable Substack Notes notifications?, updated 6 May 2025; checked 28 Sep 2026). That changes interruption. Items still land in Activity.
Pause notifications is Note-level. The three-dot menu on a Note includes Pause notifications for that conversation (Notes notifications Help, 16 Jun 2025). Useful for a runaway thread. Weak as a system for dozens of Notes.
Keep the settings walkthrough in How to Manage Substack Notifications. The short version for this page: mute likes on push if they wake you, keep replies and mentions audible if conversation is part of growth, then accept that the native Substack activity feed will still accumulate.
Practical rule: stop asking the bell for a clear button. Decide which signals earn a reply, then use a list that clears what you already handled.
How creators use the feed as a growth inbox
The Substack activity feed gets useful when you read it the way you'd read a support inbox: who needs an answer, and what's spreading.
Replies as retention
A thoughtful reply keeps a reader in the thread and often seeds the next Note. Open the parent Note, answer in one or two sentences when a short answer works, and capture any question that deserves a longer post. Paid or high-intent questions (refund worry, upgrade ask, collaboration) leave Activity and enter your real support or sales queue.
📅 Struggling to stay consistent on Substack?
WriteStack's Smart Scheduling lets you batch and queue Notes in minutes. Grow on Substack without burning out.
Explore Smart SchedulingMentions as warm distribution
A mention puts your name in someone else's audience. Reply when the mention is genuine. Restack only when you'd share that Note even if it didn't mention you. Mentions that are drive-by tags can get a like and silence.
Restacks as hook research
When the same Note keeps restacking, the first line or the claim inside is doing work. Write down the pattern. Next week's outbound Notes should echo the shape, which is easier when you also batch a queue (How to Queue Substack Notes) instead of improvising one composer at a time.
Subscribers and followers as a weekly check
New subscribers and followers feel urgent. They are weekly analytics. Once a week, pair spikes with which notes bring subscribers so you reinforce converting Notes instead of celebrating the badge every morning.
Likes as optional ambient noise
Likes are fine. They rarely need labor. If you already muted like push, you can leave likes unread in Activity without guilt. Substack will not clear them (bell Help, 16 Dec 2025).
Practical rule: end every Activity session with one outbound action (a reply sent, a Note idea captured, or a restack researched). A session where you only "caught up" and didn't answer or write anything didn't move you forward.
That inbox mindset works on native Substack. It stays slow because context is one click away, items never dismiss, and likes keep regenerating the pile. That friction is where WriteStack Activity Center sits.
Native Activity versus WriteStack Activity Center
Activity Center turns the notification chore into a short daily pass. It filters Substack notifications down to comments, mentions, and meaningful replies, lets you answer with keyboard shortcuts, and clears items once you've handled them. Substack's feed stays the full record. Activity Center is where you do the replying.
| Job | Native Substack Activity | WriteStack Activity Center |
|---|---|---|
| Default view | Full mix: likes, replies, mentions, restacks, subscribers, recommendations | Comments, mentions, and meaningful replies first |
| Clear handled items | Cannot clear Activity (Help, 16 Dec 2025) | Auto-clearing after you handle items |
| Context while replying | Open each item to reconstruct the Note | Parent Note or post shown above each reply, grouped by thread |
| Speed | Mouse-heavy scrolling | Keyboard shortcuts for rapid reply |
| Place in the week | Isolated bell tab | Next to Notes queue, Advanced Statistics, and Sync |
One thing to know before you start: WriteStack publishes Notes through Sync plus its Chrome extension, so your browser does the posting. After you queue Notes (including ones a good reply inspired), open WriteStack and click Sync so the extension can publish them on schedule (how Sync works).
Replying and posting happen in the same place. When a comment deserves a public answer, turn it into a Note and drop it into your queue. After you Sync, it publishes on schedule, with optional cross-posting through Buffer.
Open Activity Center on a 7-day trial and run one replies-first pass on yesterday's pile.
A daily and weekly Activity Center workflow
Use native Activity when volume is tiny. Use Activity Center when the red bell starts deciding your mood.
Daily (10 to 20 minutes)
- Open Activity Center after Substack is connected in WriteStack.
- Filter to comments or mentions for the high-intent slice. Switch to All after a few days away.
- Reply with keyboard shortcuts so you stay in the list.
- Let handled items clear so tomorrow starts at the new edge.
- Capture one outbound Note when a thread deserves a public answer. Queue it, then click Sync so the Chrome extension publishes on schedule.
- Skip likes unless you have spare minutes.
Weekly (30 minutes)
- Skim restacks and subscriber spikes from the week.
- Open Which Notes Bring Subscribers and reinforce the Notes that converted.
- Check Substack Notes analytics for where native View stats stop and Advanced Statistics continues.
- Revisit Engagement toggles only if interruption crept back; full settings steps live in How to Manage Substack Notifications.
When I built Activity Center, clearing about 30 comments took me about 45 minutes on Substack. Now it takes about 5 (my Note on it). Your time will depend on how many replies you get and how long you write back. Either way, you jump between tabs less, likes stay out of the way, and handled items leave the list.
Practical rule: keep Substack Engagement settings strict, then do human replies in Activity Center. Let Substack's feed be the archive, and do the actual replying somewhere that clears.
Frequently asked questions
What is the Substack activity feed?
It is the Activity section behind the bell icon: likes, replies, mentions, restacks, subscriber and follower notices, and some recommendations. Substack Help defines the bell as Activity (bell icon Help, updated 16 Dec 2025; checked 28 Sep 2026). You can engage from the tab. The feed is private to you as a list.
Can I clear or reset the Substack activity feed?
No. Substack Help states that the Activity section cannot be cleared nor notifications disabled (same bell article, checked 28 Sep 2026). You can mute email and push categories. The in-app feed remains. WriteStack Activity Center clears items from its own list once you've handled them.
Is the activity feed the same as push notifications?
No. Push and email are interruption channels you can mute under Engagement (disable Notes notifications, updated 6 May 2025; checked 28 Sep 2026). Activity still records likes, replies, restacks, and mentions when those alerts are off. App Help notes you can still see activity by tapping the bell when push is toggled off (checked 28 Sep 2026).
How should I prioritize items in the Substack activity feed?
Replies and mentions first, restacks and new subscribers second (especially in a weekly review), likes last or never. Pause notifications on a single Note only for runaway threads (Notes notifications Help, 16 Jun 2025).
How is WriteStack Activity Center different from the native feed?
Substack Activity is a complete log that cannot be cleared. WriteStack Activity Center filters toward comments, mentions, and meaningful replies, supports keyboard replies, and auto-clears handled items. It works alongside Substack, next to Notes scheduling, Advanced Statistics, Buffer cross-post, and Sync.
Where do I change notification settings?
substack.com/settings under Engagement (and related sections). Step-by-step toggles, digests, and Android categories are documented in How to Manage Substack Notifications.
Start the trial with a feed that shrinks
You already know how to open the bell. The writers who stay responsive treat the Substack activity feed as a growth inbox: replies and mentions as work, restacks as research, likes as optional ambient noise. WriteStack Activity Center makes the pass short: filters for comments and mentions, keyboard shortcuts, auto-clearing items, and a straight line into the Notes queue when a comment deserves a public answer.
Open WriteStack, start the 7-day trial, run one Activity Center pass on yesterday's replies, then Sync any Note you queued from a thread. A week later the change is simple: readers get answers, the native feed keeps its full archive, and you stop measuring the morning by how red the icon looks.
