LeadSharkLinkedIn comment to DM automation that answers every commenter
Someone comments "guide" on your post. Within minutes they get a reply under their comment and a DM with your lead magnet, and you didn't copy and paste a thing. LeadShark watches your LinkedIn posts for the keywords you pick, replies to each commenter, sends them the resource and connects with the ones you're not connected to yet.

How to auto DM people who comment on your LinkedIn post
Doing it by hand works for 20 comments. At 300 it eats your afternoon, and the people who commented first wait hours for a link they asked for. Here's what LeadShark does instead.
1. Pick the post and the keyword.
Choose a live or scheduled post and set the word people should comment, like "guide" or "template". You can add up to 20 keyword triggers per automation, or answer every comment.
2. Reply under the comment.
LeadShark posts a reply to each matching comment using a template you write, so the commenter and everyone reading the thread can see the resource is on its way. Comments you've already answered are skipped.
3. Send the DM with your lead magnet.
The commenter gets a DM with your link. Track who clicked, or send them to an email-gated page first and sync the emails to Kit or Beehiiv.
4. Handle people you're not connected to.
A normal DM only reaches 1st-degree connections. For everyone else, LeadShark sends a connection request and delivers the DM as soon as they accept. On Apex, it can also DM commenters you aren't connected with.
5. Follow up if they go quiet.
Add a follow-up DM that only goes out if they haven't replied, and filter it to people who fit your ideal customer.
Every reply and DM is a template you write. LeadShark doesn't generate AI replies and doesn't run outbound sequences to cold lists. It only talks to people who commented on your post and asked.
Who it's for
Creators and ghostwriters posting lead magnets every week who are tired of spending the day after a good post in their inbox.
Founders doing founder-led sales who want comments on their posts to turn into conversations, not just reactions.
Agencies running posts for several clients. APEX+ covers 3 LinkedIn profiles under one account.
Company Pages. Pro+ and Apex can run an automation on a Company Page post, and Apex can auto-reply as the page.
If you've used ManyChat on Instagram, this is the same idea for LinkedIn. ManyChat doesn't connect to LinkedIn, which is why we wrote ManyChat for LinkedIn: does it work?
Safety and limits
LinkedIn notices accounts that send hundreds of identical messages in a burst. LeadShark is built around pacing, not speed.
| Setting | What you get |
|---|---|
| Daily DM limit | You set 0 to 250 (150 recommended max) |
| Connection requests | Up to 80 a day and 200 a week |
| Pacing | Human-like delays between actions, plus safety cooldowns |
| Off-hours | Nothing sends overnight in your timezone when you turn it on |
| Warm-up mode | A randomized, lower daily limit for new accounts |
LeadShark runs in the cloud. The Chrome extension is used once at setup to connect your account, and you don't need it after that. It doesn't drive your browser or click around for you.
No tool is risk-free, so start conservative and ramp up. You can set the DM limit anywhere up to 250 a day, and we recommend a maximum of 150.

FAQ
How do I automatically DM people who comment on my LinkedIn post?
Connect your LinkedIn account to LeadShark, pick the post, set the keyword and write your reply and DM. From then on, each matching commenter gets a reply under their comment and a DM with your link, in under 10 minutes on average.
Can I send a DM to someone who commented but isn't a connection?
LinkedIn only allows normal DMs between 1st-degree connections. LeadShark sends those commenters a connection request and delivers the DM once they accept. On Apex, it can also DM them without waiting.
Does it work on posts that are already live?
Yes. You can attach an automation to a post that's already up, or schedule a post with the automation attached so it starts the moment you publish.
Is LinkedIn comment automation safe?
It's as safe as the limits you run it with. LeadShark keeps sending inside your daily DM limit with human pacing, off-hours and warm-up mode. You set 0 to 250 DMs a day, and we recommend a maximum of 150.
Do I need to keep a Chrome extension or my browser open?
No. The extension is used once at setup to connect, and everything runs in the cloud after that.
Is there a ManyChat for LinkedIn?
ManyChat doesn't support LinkedIn. LeadShark does the same comment to DM flow on LinkedIn, including commenters who aren't connections. More in ManyChat for LinkedIn.
Can I capture emails, not just send a link?
Yes. Send commenters to an email-gated lead page, then export to CSV or Google Sheets, or sync to Kit and Beehiiv.
Can I set this up from Claude or ChatGPT?
Yes. Pro+ and Apex connect to our LinkedIn MCP server, so you can say "DM everyone who comments guide on my next post" and your agent sets it up.
