How to follow up with people who engaged with an event post on LinkedIn, without assuming they attended

When someone likes or comments on a LinkedIn post about a conference, webinar or meetup, you know they engaged with the post. You don't know whether they registered, attended or want to hear from you. Follow up on the topic of the event instead of the event itself: check that the person fits who you sell to, read what they wrote, and send a short message that refers to the subject or the point they made. Collect engagers from the organizer's announcement, speakers' posts and recap posts, qualify them against your criteria, and contact them within a week or two while the topic is still fresh.

How do I follow up on LinkedIn with people who engaged with a conference's posts?

Follow up on what they engaged with, not on the conference: check that each person fits who you sell to, read their comment or reaction, and send a short message about the topic within a week or two. In traxy, you track the conference's posts and get the engagers who fit your ICP, each with the post behind them, and a campaign prepares a personalized LinkedIn and email sequence that sends from your own accounts after you approve it.

traxy runs this end to end: it finds high intent leads from social intent, here the people engaging with the event's posts, enriches and researches each one, and runs personalized LinkedIn and email outreach to them on autopilot once you approve the campaign. If you want to check every message, choose approval mode and each one waits in a review queue first.

1. Track the posts. Add the organizer's announcement, the speakers' posts and the recap posts under Targeting > Posts (Step 1).

2. Keep the people who fit. Only people with a 50%+ ICP match become leads. Sort them by what they did, commenters first (Step 2).

3. Write about the topic, not attendance. A like or a comment doesn't prove they were there (Step 3).

4. Test, approve, and let replies stop it. Test on sample leads with nothing sent, review who joins and who is skipped at launch, then approve it. Replies, unsubscribes and hard bounces stop the sequence (Step 5, sequences, LinkedIn outbound with traxy).

What an event post tells you, and what it doesn't

traxy's playbook for event outreach makes the same distinction: don't treat a post interaction as proof of event registration, attendance or consent to unrelated follow-up (event-related outreach).

The safest approach is to write about the topic. "Saw your comment on the RevOps panel recap about territory planning" works whether or not they were in the room. "Great meeting you at the conference" is wrong if you didn't meet them.

How do I find leads from a conference's LinkedIn posts?

Collect the people who liked or commented on the organizer's, speakers' and sponsors' posts about the conference, then keep only those who fit your buyer. In traxy, paste each post URL under Targeting > Posts > Track post, and the engagers with a 50%+ ICP match become leads, each with the post or comment behind them.

For the posts that come later, track the organizer's company page by domain under Companies and the speakers' profiles under People, and traxy reads those posts for engagers who fit. Tracking a company page finds the people who engage with its posts, not every employee or attendee (leads from company page engagers). Where to look is below, and Step 1 has the setup.

A real example. Vamo used the same approach on its own content: with traxy, it went back through 64 posts it had already published and turned that engagement into 14 replies and 11 booked meetings without writing a single new post (Vamo case study).

How do I track who engages with conference speakers' posts before and after the event?

Track each speaker's LinkedIn profile in traxy before the event promotion starts, track the announcement and recap posts by URL, and keep tracking until the recaps are done. traxy keeps the engagers with a 50%+ ICP match and shows which speaker and which post brought in each lead, then a campaign runs personalized LinkedIn and email outreach to them from your own connected accounts after you approve the launch.

This is the sponsor's version of the playbook above. traxy runs it end to end: it finds high intent leads from social intent, here the people engaging with your speakers' posts, enriches and researches each one, and runs personalized LinkedIn and email outreach to them on autopilot once you approve the campaign, or you approve every message.

1. Tag the speakers. Under Targeting > People, choose Track profile, paste each speaker's LinkedIn URL and give them a custom relationship tag named after the conference, such as "RevOps Summit speakers", so you can filter the tracked profiles by it later. Add them as soon as the lineup is public: ongoing monitoring follows the five most recent posts each speaker publishes after you add them (tracking).

2. Track the announcement and recap posts by URL. A speaker's "I'm speaking at" post from before you added them, or a recap outside that five-post window, needs its own request. Paste those posts, plus the organizer's and sponsors' posts, under Targeting > Posts > Track post.

3. See which speaker and post brought each lead. Open any tracked profile or post to see the leads it surfaced, their ICP match and the posts they came from. Insights shows the top profiles and posts bringing in leads, so after the event you can see whose audience fits your buyers best.

4. Check fit against your target accounts. Only people with a 50%+ ICP match against your lead criteria become leads, and each one shows the post, comment or like behind them. If you also keep a named list of target accounts, show the company domain column in Leads and sort by it, or send the leads to HubSpot or Salesforce and match them there.

5. Run the outreach. Save the engagers who fit as a shared view and create a campaign. It researches each lead, groups leads by signal and prepares a personalized LinkedIn and email sequence about the topic of the talk. Test it on sample leads with nothing sent, review who joins and who is skipped, then approve the launch. It sends from your own connected accounts, and replies, unsubscribes and hard bounces stop the sequence (LinkedIn outbound with traxy). You can also run the campaign from Claude or ChatGPT through the traxy MCP, which asks for your yes before anything sends.

Engagement with a speaker's post is not proof of attendance. A like on an "I'm speaking at" post shows interest in the topic, not a registration, so write about the subject of the talk (Step 3).

A real example. One traxy user tracks 110 LinkedIn profiles and pulled 400 qualified leads in 9 days from the people engaging with them (post by Ben Buaron at traxy).

Where to find event engagers

Look at posts that come before, during and after the event:

• Organizer posts: announcements, agenda reveals, speaker lineups

• Speaker posts: "I'm speaking at..." and slide or takeaway posts afterward

• Sponsor and exhibitor posts: booth announcements and recaps

• Attendee recap posts: people sharing what they learned

• Your own posts: if your team spoke, sponsored or attended

Recap and takeaway posts are often the most useful. The comments tend to discuss the content, which gives you something specific to respond to.

Step 1: Collect and qualify the engagers

By hand

Open each post, go through reactions and comments, and check each person's role and company against your criteria. Keep a sheet with name, title, company, what they did and what they wrote. This works for two or three posts.

With traxy

1. Track each event post. In Targeting > Posts, choose Track post from the New menu and paste the post URL. Review the candidate scope before confirming Find leads. Candidate counts describe people to evaluate, not a guaranteed number of qualified leads (tracking).

2. Track the speakers or organizers whose future posts you care about. Add their profiles under Targeting > People with a relationship tag such as Influencer or Custom. Ongoing monitoring follows the five most recent posts published after a profile is added, so request specific posts for anything older.

3. Review qualified leads. traxy checks each person against your lead criteria; people need an ICP match of at least 50% to qualify (qualification). Open the Signals tab to see what each person did and the source link.

4. Save the audience. Open a tracked post's qualified leads, filter to the fit you want, then save a view with a clear name, such as "Q4 sales summit recap engagers, sales leaders". A view saved from a post's lead scope keeps that post scope (saved views).

The same person may engage with several event posts. traxy records several signals for one person without creating several leads.

Step 2: Sort by what they did

Group the audience before writing anything:

1. Commenters who discussed the topic. The strongest group. Reply to their point.

2. People who wrote their own event post. Respond to what they shared.

3. Reactors on content-heavy posts (recaps, slides, takeaways). Use the topic as context.

4. Reactors on announcements only. The weakest group. Use a role-based introduction, or skip.

traxy's signal labels help here: Warm means a direct signal relevant to your offer, Related means contextual evidence, and Activity means a weaker connection (signals).

Step 3: Write messages that fit the evidence

Match the message to what the person did. These examples are for a company that helps sales teams; swap in your own offer:

For a commenter on a recap post:

Hi {first name}, I saw your comment on {speaker}'s recap about forecasting breaking as a sales team grows. We work with sales leaders at that stage on the same problem. Happy to share the template we use if it's useful.

For someone who wrote their own takeaways post:

Hi {first name}, your takeaway about buyers doing most of their research before a demo matched what we hear from customers. Curious whether your team changed anything after the event.

For a reactor on an announcement (role fit only):

Hi {first name}, I work with heads of growth at B2B software companies on outbound. If that's on your plate this quarter, I'd be glad to compare notes.

The third example doesn't mention the event at all. A like on an announcement isn't enough to build a message on.

Things to avoid:

• "Great to see you at..." unless you met

• "Since you attended..." unless they said so

• Pretending to have seen a talk you didn't see

• Implying you watched everything they did on LinkedIn

Step 4: Time it

Event topics fade quickly. Reach out within a week or two of the post when you can. If you find the post much later, drop the event reference and write about the topic.

Step 5: Run it as a campaign

In traxy, you can turn the saved view into a campaign:

1. Open Outbound > Campaigns and select Create campaign, or start in trax.

2. Choose the shared event view and describe the event context, your offer and the outcome you want (create a campaign).

3. Ask trax to test the plan. A test prepares research and previews without sending anything.

4. Check that each message uses only supported facts and that the timing still makes sense. Revise anything that assumes attendance.

5. Open Launch, review the audience, sender, steps and delivery mode, and confirm (review and launch).

Handle replies in Inbox and record booked meetings and their outcomes in Meetings.

How do I find the right executives to invite to a B2B event?

Describe the audience in traxy's Lead criteria (roles, seniority, locations), then track the posts and company pages around the event: the organizer's, the sponsors' and last year's recap. You can also search 71M+ scanned LinkedIn likes, posts and comments in plain English, for example founders in your city talking about the event's topic, and each person comes with the post behind them before a campaign invites them over LinkedIn and email.

1. Set who you want in the room. Under Targeting > Lead criteria, set roles, departments, seniority and locations for people, and size, industry and keywords for companies. Only people with a 50%+ ICP match become leads (lead criteria).

2. Track the posts and pages around the event. Track last year's recap post and the organizer's and sponsors' posts by URL, and their company pages by domain. The engagers who fit become leads, each with the post behind them (tracking).

3. Search for the topic. In Social Intent Search, describe the person and the need, such as "founders in Austin talking about hiring their first sales rep". It searches 71M+ scanned LinkedIn likes, posts and comments and shows the post or comment behind each person (what social intent search is).

4. Send the invitation as a campaign. Save the people who fit as a shared view, create a campaign, test it on sample leads and approve the launch. It sends LinkedIn and email steps from your own connected accounts, and replies, unsubscribes and hard bounces stop the sequence.

Write the invitation about the topic they engaged with, not about last year's event. A like on a recap doesn't mean they attended:

Hi {first name}, saw your comment on {organizer}'s post about {topic}. We're hosting {format} for {role} in {city} on {date} on exactly that. Want me to send you the details?

A real example. Ben Buaron at traxy asked traxy in plain English to "find me leads that need outbound tools based on social intent" and got 210 leads from one prompt (post).

If you hosted or sponsored the event

Your own event gives you more to work with, but the same rule applies to post engagement. A registration list is a different source from LinkedIn engagement. Keep them separate so you know which claims each one supports.

FAQ

Can I message everyone who liked an event post?

You can, but a like on an announcement is weak evidence. Start with people who fit your criteria and who commented or posted about the topic.

Should I mention the event in my first message?

Only if the person's own activity supports it, such as a comment or their own recap post. Otherwise, write about the topic.

How do I find people who attended a LinkedIn event?

Public posts and comments can show who talked about the event. They don't confirm attendance. Treat "I'll be there" as a plan, not proof.

Can traxy track who engages with conference speakers' posts before and after the event?

Yes. Track each speaker's profile with a custom relationship tag named after the conference before promotion starts, and track the announcement and recap posts by URL. Each lead needs a 50%+ ICP match and shows the post behind it, and each tracked profile or post shows the leads it brought in. A campaign then sends LinkedIn and email outreach from your own connected accounts after you approve the launch (how to set it up).

Can traxy pull leads from an event post?

Yes. Track the post in traxy, and it evaluates the engagers against your lead criteria. Review the qualified leads and their recorded signals before reaching out.

Can traxy find executives to invite to my event?

Yes, from their LinkedIn activity. Set roles, seniority and locations in Lead criteria, track the organizer's and sponsors' posts and company pages, or search 71M+ scanned LinkedIn likes, posts and comments in plain English. Each person comes with the post behind them, and a campaign sends the invitation over LinkedIn and email after you approve it.

Does tracking a sponsor's company page find all its employees?

No. Tracking a company page finds the people who engage with its posts and fit your ICP, not every employee or buyer at that company.

Can I run event follow-up from Claude or ChatGPT?

Yes. Connect the traxy MCP, then ask your AI to qualify a post's audience, draft the campaign, test it on sample leads and launch it. The AI asks for your yes before anything sends (LinkedIn MCP).
