A better LinkedIn inbox, so no follow-up slips
By Tirth Shah, founder of Bub · Updated
LinkedIn's own inbox only has a few fixed filters, like Unread and Starred. It has no labels, no follow-up reminders and no way to split your DMs. Bub Pro is a fast, keyboard-first inbox for your LinkedIn messages: label any chat, give each label its own split inbox, press H to have a chat come back when it's time to follow up, and move through it all from the keyboard. It's free for 14 days, no card needed.
Add Bub to Chrome, it's freeWhy LinkedIn's inbox loses follow-ups
LinkedIn sorts every conversation by the last message. A prospect who said "ping me next month" sinks under twenty newer chats by Friday, and nothing brings them back. Recruiters, founders and SDRs end up keeping spreadsheets, sticky notes or a CRM tab open just to remember who to follow up with.
The fix is the same one email got years ago: labels, split inboxes, reminders and keyboard shortcuts.

How to set up the Bub inbox
- Add Bub to Chrome. Install Bub from the Chrome Web Store. The inbox talks to LinkedIn through the extension, in your own browser.
- Open your inbox. Go to heybub.so/inbox and sign in. Your LinkedIn conversations load straight from LinkedIn into your browser.
- Label what matters. Press L on a chat to label it, like Prospects, Clients or Candidates. Each label can become its own split inbox.
- Set reminders. Press H on any chat and pick when. It leaves your inbox and comes back at the top at that time.
- Fly through it. J and K to move, E to archive, Enter to open, ⌘K for anything else. Press ? any time for every shortcut.
Who it's for
Anyone whose work runs through LinkedIn DMs: founders doing their own sales, SDRs and AEs, recruiters, agency owners and creators with a busy inbox. If you've ever lost a deal or a candidate because a chat sank, it's built for you.
Bub Pro is priced per LinkedIn inbox, not per person: $15 a month billed yearly, or $35 monthly, and teammates are free. The Bub extension, with voice notes, video and snippets inside LinkedIn, stays free either way.
Questions
Is there a Superhuman for LinkedIn?
Yes, that's the Bub inbox. It's a fast, keyboard-first inbox for your LinkedIn messages: split inboxes by label, follow-up reminders, snippets, notes on people, a key for every move and ⌘K for everything.
Can I label my LinkedIn messages?
Not in LinkedIn itself, which only has fixed filters. In the Bub inbox you can add your own labels to any conversation with L, and turn each label into its own split inbox.
How do I set follow-up reminders on LinkedIn?
In the Bub inbox, press H on a conversation and pick when. The chat leaves your inbox and comes back at the top at that time, so you follow up on time.
Does it read or store my messages?
Conversations load from LinkedIn straight into your browser. Bub stores only what you create in Bub, like labels, notes, snippets and reminders. It never asks for your LinkedIn password.
How much does it cost?
Bub Pro is free for 14 days with no card. Then it's $15 per LinkedIn inbox a month billed yearly, or $35 monthly. Teammates are free, and the extension is free forever.
Does it work with Sales Navigator?
Not Sales Navigator's own inbox. The Bub inbox works with your LinkedIn messages.
