NEW · AI SPAM FILTER
Your LinkedIn inbox, minus the spam.
Linbox uses AI to move cold pitches and recruiter blasts out of your inbox automatically, so the only messages left are the ones that actually matter.

Hey! Saw your post on data pipelines, really good read.
We're actually dealing with the same issue at work right now.
Glad to hear it. Was a real challenge to figure out, honestly.
Would you be open to a quick call this week? Would love to compare notes.

For people whose inbox is too important to lose to spam.
We built Linbox because people keep saying things like this.
Public LinkedIn posts about LinkedIn's inbox.
“My LinkedIn inbox is a graveyard of unanswered requests.”
“My LinkedIn inbox is 90% spam. I'm done.”
“My LinkedIn inbox is so full of people trying to sell me shit I'm missing the messages from people I'm actually trying to buy from.”
“What about the 2% of messages from people you know IRL that you actually want to catch up with?”
“My LinkedIn inbox is a total and complete catastrophe.”
“When everything is sitting in one giant messy inbox, it becomes easy to ignore.”
THE SPAM PROBLEM
Most of your LinkedIn inbox isn't even for you.
Cold sales pitches. Templated recruiter blasts. "Quick question" automation. They bury the handful of messages that actually matter, until opening LinkedIn feels pointless.
Linbox sorts it out for you. Automatically.
It reads the noise so you don't have to.
AI scores every unanswered cold message. The obvious junk goes straight to a separate Spam bucket. Your inbox keeps only the real conversations.
Nothing is ever deleted.
Spam sits in its own bucket, one click away. Reply to anyone and they leave Spam instantly. You stay in control.
See it work on day one.
Turn it on and Linbox checks your last 30 days right away. Most people watch dozens of dead-weight threads clear out in seconds.
Private by design: message previews are scored in real time and never stored. Turn the filter off anytime.
The more important you are, the worse your inbox gets
Reach a certain level on LinkedIn and the cold outreach never stops. Here is why your inbox stopped being usable.
The volume problem
AI tools and outreach platforms blast LinkedIn at scale. Every day brings more cold pitches. The share that actually matters to you keeps shrinking.
The disguise problem
"Hey [Name]." "Saw your profile." "Quick question." Cold templates are so predictable that genuine messages get dismissed in the very same scroll.
The paralysis problem
When the people who matter are buried under outreach you never asked for, the easiest move is doing nothing. Real opportunities slip away.
Spam gone. Now keep your inbox that way.
Labels & Organization

Same product. Different reasons your inbox matters too much to ignore.
If you're a founder
Your next investor, hire, or customer is in there.
Somewhere under 200 cold pitches. Linbox clears the noise so the messages that move your company forward are the ones you actually see.
If you invest
Founders reach out. So do the vendors.
Real dealflow and warm intros get buried under everyone selling you software. Linbox keeps the founders in your inbox and the rest out of the way.
If you create
Your audience writes back. So do the pitches.
Followers, collaborators, and brands share the same inbox as endless cold outreach. Linbox surfaces the people who actually care.
If you lead
The intro that matters, lost between cold demos.
Partners, candidates, and peers reach you in your DMs, right alongside the pitches. Linbox makes sure the important ones stop slipping past.
