How does a CRM unify email, LinkedIn, and sales activity?

It stores every interaction on the contact and company it belongs to, in one timeline. Email, LinkedIn and chat messages, meetings and notes sit side by side, so anyone picking up the account sees what happened, who did it and when.

Why teams ask

Reps email from Gmail, message on LinkedIn and chat on WhatsApp. Notes live in personal tools. When someone else takes over the account, they start blind.

  • Conversations stay in private inboxes.
  • LinkedIn messages never reach the CRM.
  • Managers cannot see what is going on without asking.
  • Handoffs are slow because the history has to be retold.

What goes wrong in most CRMs

  • Email sync shows subject lines, not the conversation.
  • LinkedIn is a profile link, not a channel.
  • Each channel has its own tab, so the order of events is lost.

Reps then keep relying on their inbox, and the CRM becomes a place to report, not to work.

How Lumenbase does it

One timeline per record

Every contact and company page has a timeline of the email, LinkedIn and chat messages, meetings, calls and notes that involve it, newest first.

Connected channels

ChannelHow it connects
Gmail and OutlookEach person connects their own mailbox and calendar. Mail and meetings sync to the matching contacts.
LinkedInThe Lumenbase browser extension syncs messages and connections to the contact.
WhatsApp, Telegram and SignalLink your own account. Chats sync to the matching contact.

One inbox for replying

Communication collects every connected channel in one inbox, with views such as Needs Reply and Waiting on Them and a filter per channel.

Who can see a conversation

Synced conversations belong to the person whose account they came from. Each person picks a default per channel in SettingsPersonalPrivacy. Only the owner can change who sees a single conversation.

SettingWho sees it
PrivateOnly the owner. This is where new conversations start unless you change the default.
Shared with someThe owner and the people, teams or roles they add. Admins are not included unless added.
Fully SharedEveryone in the workspace who can open the record.

Examples

Account handoff

An AE opens the contact and reads every shared email, LinkedIn message and meeting in order.

Manager review

A manager opens the company and sees shared conversations across all its contacts in one place.

Multi-threaded deals

Several contacts at one company each keep their own timeline, and the company page shows them together.

FAQ

Do reps need to log everything by hand?

No. Connected channels sync on their own. Notes and calls without a connected channel are added by hand.

Can several people see the same conversation?

Yes, when its owner sets it to Fully Shared or adds them under Shared with some.

Does this replace my email inbox?

No. You can keep using Gmail or Outlook. Lumenbase keeps the shared history next to the record.

How is LinkedIn handled?

Through the browser extension. Messages attach to the contact instead of staying on LinkedIn.
