Contact graph: the memory of your professional relationships

Your inbox doesn't just hold messages. It holds your network: clients, colleagues, suppliers, partners, and the history of each relationship. A contact graph makes that network visible and usable, for you and for your AI assistant.

What is a contact graph?

A graph, in the mathematical sense, connects nodes with edges. In a contact graph, the nodes are people and organisations; the edges are your exchanges.

Each edge carries information: how many messages you've exchanged, when the last one was, what kind of relationship it is (client, colleague, manager, supplier), and which organisation the person belongs to.

Where an address book is a static list, the graph is alive: it updates with every email sent or received.

Why it helps day to day

Prioritise. An email from a client you talk to every week doesn't weigh the same as an unknown cold pitch. Knowing the relationship helps you decide what to handle first, in the spirit of the prioritization matrix.

Reply well. You don't write to your manager the way you write to a supplier. Knowing who the person is, and rereading your latest exchanges, helps you find the right tone and avoid asking a question that's already settled.

Never let a relationship go cold. The graph shows the important contacts whose last exchange was weeks ago. That's the basis for well-timed follow-ups.

How it's built from your email

No need to type everything in by hand: every email received or sent adds or strengthens an edge. The sender becomes a contact, the exchange count goes up, the last-contact date updates.

The address domain links the person to an organisation. An AI can then suggest the relationship type from the content of the messages, as long as it's confident enough; you can always correct it.

Mind the privacy side: a contact graph says a lot about your activity. Check where it's stored, that access to your inbox is read-only, and that a GDPR-compliant data processing agreement (DPA) exists.

The contact graph in Virtus Lever

Virtus Lever builds this graph automatically while syncing your inbox. For each contact it keeps the number of exchanges, the date of last contact, the organisation and the relationship type, detected by AI when it's confident enough and editable at any time.

That context is put to work: suggested replies draw on the relationship and your latest exchanges to strike the right tone, and your personal assistant knows who you mean when you ask it a question.

The connection to your inbox is read-only and data is hosted in the EU. Your contact graph stays yours: it's the memory of your relationships, alongside the memory of your documents described in personal RAG.
