How to Get Notified When Someone Posts on Linkedin or X
Say there's one person whose posts you can't afford to miss. Maybe it's the VP who just became your champion's new boss, or a competitor's CEO who tends to announce things on Linkedin before the press release goes out. You check their profile every morning for a week. Then you get busy, and the post you were waiting for goes up on a Thursday afternoon. You find it on Monday, with 300 comments under it.
Both Linkedin and X have a built-in fix for this, and for a lot of people it's enough. I work on MultiFollow, a tool that sends alerts when specific Linkedin and X accounts post, comment, or like, so keep that in mind as you read. I'll start with the free option that's already in the apps, then get to where it stops working.
The bell on Linkedin and X
Linkedin calls it subscribing to a member's content. You open the person's profile, click the bell icon near their photo, and choose All. From then on you get a notification each time they post. The other option, Most relevant, lets Linkedin pick which posts are worth telling you about, and Linkedin doesn't say how it picks. For anyone you really care about, choose All.
There's a catch you'll hit right away. The bell only shows up on profiles you're connected to or already follow. So if this is a prospect you don't know, you have to click Follow first. Following doesn't need their approval, but it does put your name in their followers list. Linkedin's help page says people aren't told when someone subscribes to their posts. The follow itself is a different story.
The bell also only covers posts. If the person comments on a competitor's thread or likes a post about a problem you solve, Linkedin won't tell you. And if you unfollow them later, the subscription goes away with it.
X works almost the same way. Follow the account, open its profile, tap the bell next to the Follow button, and pick All posts. The alert arrives as a push notification on your phone, mixed in with your likes, replies, and mentions.
Following on X is public, so the person can see it and so can anyone looking at their followers. For a journalist following a politician, that's fine. For a sales rep following a prospect at an account they haven't approached yet, it can feel a bit early.
Where the bell stops working
For one or two people, I'd use the bell and stop there. It's free, it takes ten seconds, and the people you follow probably won't mind.
The trouble starts when it becomes part of how you work. Take a sales team watching 25 people across five target accounts. Each rep has to follow each person from their own account. Every alert lands in a personal phone, next to birthday reminders and job suggestions, so nobody else on the team sees it. There's no way to push those alerts into Slack, a CRM, or a Clay table. And the most useful signals on Linkedin (a comment on someone else's post, a like on a competitor's launch) never show up at all.
That's the gap we built MultiFollow for. You add a Linkedin profile, a Linkedin company page, or an X account as a tracker, and we check it for new activity. You don't follow anyone from your own account, so there's nothing for them to see.
What MultiFollow tracks, and what it doesn't
Coverage depends on the account type, so it helps to see it side by side.

The row that matters most for sales is the first one. A prospect commenting on a thread about your category is often a stronger signal than anything they post themselves. If you want company-level comments and likes, track the people who work there instead of the page. On X, likes have been private since 2024, so we can't track them.
One more thing we don't do is job changes. If someone switches companies and doesn't post about it, we won't flag it, so keep a job-change tool or your CRM enrichment for that.
Setting it up
The setup is short, and you can do it before your next coffee.
1. Create an account on the MultiFollow dashboard.
2. Add a tracker by pasting the Linkedin profile, company page, or X account URL.
3. Pick where alerts go. Email works on every plan. Slack and API webhooks are on Business and above.
4. Wait for the first alert, then check that it lands where your team will see it.
An email alert for a Linkedin comment looks something like this:
New Linkedin comment from Jane Doe (VP Operations, Example Logistics)
On a post by Sam Lee: "We tried three routing tools last year and
dropped two of them after the pilot. Happy to share what went wrong..."

How many people you can track depends on the plan. Plans are sized by the number of accounts you track, with separate limits for Linkedin and X. A Linkedin company page counts toward the Linkedin limit.

Free is enough to try it on the one person you'd otherwise check by hand every morning. Refresh on Free is best effort, while paid plans are near real-time. If you need Slack alerts for a team, Business is the first plan that has them.
A quick side note. If what you need is alerts when anyone mentions a keyword, not when a specific person posts, that's a different tool. Our sibling product KWatch does keyword monitoring on Reddit, X, Linkedin, and a few other sites.
Try it on one person
Think of the person whose posts you keep missing. Add them on the free plan and leave it running for two weeks. If the first comment alert shows you something you'd never have caught with the bell, you'll know whether it's worth adding the rest of the list.
