Short answer: Save the person to HubSpot with Ln2CRM, open the LinkedIn conversation and click Sync to CRM. The first sync writes up to the last 100 messages as one note on the contact, or on the linked deal. Switch on Auto-sync new messages and every later message is added as a new note while the conversation is open. HubSpot's native alternative needs Sales Navigator Advanced Plus.
Before you start
- The Ln2CRM extension installed in Chrome and HubSpot connected in Ln2CRM settings with one OAuth approval.
- The person saved in HubSpot from their LinkedIn profile. If you have not set that up yet, see the LinkedIn HubSpot integration page.
- Any Ln2CRM plan. Each sync that writes new messages uses one Manage action.
How to log LinkedIn messages in HubSpot
- Open the conversation.Open the thread in LinkedIn messaging, in a chat window opened from the person's profile, or in the Sales Navigator inbox. The person has to be in HubSpot already: the Ln2CRM badge on their profile shows In CRM once they are.
- Click Sync to CRM.The Sync to CRM button sits just above the message box, under the conversation. The number on it, for example Sync to CRM (3), is how many messages in this thread are not in HubSpot yet. Once everything is synced it reads Up to date.
- Pick the record if asked.If your setting is Deal and the contact has more than one open deal, the message box asks Which deal?. Pick one, or choose Contact instead.
- Check the result.The message box confirms with a line such as Synced 12 messages to Maya Chen. The first sync saves up to the last 100 messages in one note. If nothing is new, the button reads Up to date.
- Turn on auto-sync.In Ln2CRM settings, find Sync LinkedIn messages to, choose Contact or Deal, and tick Auto-sync new messages. Conversations you have synced once then pick up new messages on their own while they are 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.

Contact Deal
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
Open the contact in HubSpot and look at the activity timeline: the conversation is a note, so filtering the timeline to Notes finds it quickly. If you chose Deal, it sits on the deal's timeline instead. HubSpot renders note bodies as formatted text, so speaker names stay underlined and every message keeps its own line. Ln2CRM keeps each note under about 60,000 characters and continues very long threads in another note.

What gets synced and what does not
- Synced: the text of each message, who sent it and when, grouped by speaker. The first sync goes back up to the last 100 messages.
- Not synced: files, images and reactions. They stay on LinkedIn.
- Never duplicated: each LinkedIn message has a stable id, so a message already in HubSpot is skipped on the next sync.
- Not stored by Ln2CRM: message text goes to HubSpot and is not kept on Ln2CRM servers.

FAQ
Does HubSpot log LinkedIn messages on its own?
Only through Sales Navigator CRM Sync, which needs Sales Navigator Advanced Plus. The standard Sales Navigator card lets you send InMail from a contact, but HubSpot notes that the conversation is not saved to the timeline automatically.
Can the messages go to a HubSpot deal instead of the contact?
Yes. Set Sync LinkedIn messages to Deal in Ln2CRM settings. One open deal gets the note automatically; with several, Ln2CRM asks which deal.
Does it work on the free HubSpot CRM?
Yes. Ln2CRM connects to HubSpot with one OAuth approval and writes regular notes, which every HubSpot tier supports, so no Sales Hub seat is needed.
Does it log Sales Navigator InMails in HubSpot?
Yes, without Advanced Plus. The Sync to CRM button also appears in the Sales Navigator inbox and in the message panel of a lead page, and the conversation lands on the HubSpot contact as a note.
