Short answer: save the person to HubSpot through Ln2CRM, then open your LinkedIn chat with them and press Sync to CRM. You'll get one note on the contact, or on their deal, holding up to the last 100 messages. Rather not press it every time? Tick Auto-sync new messages. Each new reply then gets its own note, as long as the chat's open in front of you. HubSpot's built in route, for comparison, costs a Sales Navigator Advanced Plus seat.
Before you start
- Ln2CRM added to Chrome, and HubSpot connected in its settings. That's a single OAuth approval, nothing more.
- This person already in HubSpot, saved from their LinkedIn profile. Not done yet? The LinkedIn HubSpot integration page shows you how.
- Any plan of ours will do. You spend one Manage action each time a sync actually writes messages, and an empty sync is on the house.
How to log LinkedIn messages in HubSpot
- Open the conversation.From LinkedIn messaging, from a chat bubble you opened on their profile, or from the Sales Navigator inbox, it's all the same to us. HubSpot does need to have this person already. Not sure? Their profile badge reads In CRM if so.
- Click Sync to CRM.Right below the conversation, sitting on top of the typing box, there's Sync to CRM. Its counter, say Sync to CRM (3), tells you how many messages HubSpot hasn't seen. Nothing left to send? It reads Up to date.
- Pick the record if asked.Happens only when you've chosen Deal and the contact has more than one deal open. You'll see Which deal? in the message box. Choose one, or click Contact instead.
- Check the result.A note in the message box confirms it, along the lines of Synced 12 messages to Maya Chen. On a first sync, up to 100 recent messages go into the same note. When there's nothing fresh, you'll just see Up to date.
- Switch on automatic syncing.Go to Ln2CRM settings. Under Sync LinkedIn messages to you choose Contact or Deal, and below it you tick Auto-sync new messages. From then on, a thread you've synced once grabs new replies whenever you have it open.

✓ In CRMThanks for the demo yesterday. Could you send pricing for five seats?
Sure. On annual billing it comes to $13 per seat per month.
Got it. I am looping in Daniel from ops before we sign.

Deal: the deal linked to this contact. With no linked deal, messages go to the contact.
Auto-sync new messages
Only for conversations you have synced once, so it never interrupts you.
Where to find the conversation in HubSpot
So where did it go? Find the contact in HubSpot and look at the activity timeline. Too busy to spot it? Filter to Notes, there it is. If you went with Deal, check the deal's timeline instead. Formatting survives, by the way, with names underlined and one line per message. And a really long thread gets split once a note hits about 60,000 characters.

What gets synced and what does not
- Synced: who said what, grouped by speaker, each turn stamped with when it was actually sent (02 Sep 2026, 10:14, say) in your time zone. No vague "Wednesday". The first run reaches back as many as 100 messages.
- Not synced: attachments, photos and emoji reactions. We leave them on LinkedIn.
- Never duplicated: how do we know what HubSpot already has? Every LinkedIn message comes with an id that never changes. Seen it before, skip it.
- Not stored by Ln2CRM: the text travels to HubSpot. Our servers keep none of it.

| Connect a CRM in Ln2CRM settings first | HubSpot is not connected | Connect HubSpot in Ln2CRM settings |
| Ln2CRM updated in the background | The extension updated while LinkedIn was open | Click Reload page |

FAQ
Does Ln2CRM keep the time each LinkedIn message was sent?
Yep, to the minute. Open the note and every turn has its real send time, 02 Sep 2026, 10:14 or whatever it was, in your time zone. We pull it from the message itself. That's why you'll never see LinkedIn's "Wednesday" there, or the minute you clicked sync. Somebody sent four messages in a row? One name and time line covers all four.
Does HubSpot log LinkedIn messages on its own?
Only via Sales Navigator CRM Sync, and that needs Advanced Plus. The regular Sales Navigator card does let you send an InMail from a contact, but HubSpot itself points out that the conversation isn't saved to the timeline by itself.
Can the messages go to a HubSpot deal instead of the contact?
Sure can. Change Sync LinkedIn messages to Deal in Ln2CRM settings. One open deal, and the note goes straight onto it. Several? We'll ask you which.
Does it work on the free HubSpot CRM?
It does. You connect HubSpot with one OAuth approval and we write ordinary notes, which every HubSpot tier has, so there's no Sales Hub seat to buy.
Does it log Sales Navigator InMails in HubSpot?
Yes, and you don't need Advanced Plus for it. You'll find the Sync to CRM button in the Sales Navigator inbox and in the message panel on a lead page too, and the chat ends up as a note on the HubSpot contact.
