How Expandi works with Master Inbox

It's built to let you scale sends, but scaling replies is a different problem, LinkedIn's inbox can't keep up. Master Inbox pulls every Expandi conversation into one inbox with your email replies, tagged and filterable, so warm LinkedIn replies never get buried.

Every LinkedIn reply is labeled by intent as it lands, using thirteen default labels or your own taxonomy, on your own OpenAI, Anthropic or OpenRouter key. Reps open the interested conversations first and the rest wait in saved views.

Which CRMs can Expandi conversations reach through Master Inbox?

HubSpot, Pipedrive, Attio, GoHighLevel and Close sync with the conversation, label and stage, and Salesforce is covered through webhooks and our OutboundSync partnership. Keep Expandi for sending and let Master Inbox do the logging.

Is Master Inbox priced per seat?

No. Master Inbox is priced on connected mailboxes and client workspaces, with unlimited users on every plan, so adding a rep or a client login never adds a seat fee. Every plan starts with a free 7-day POC, and the pricing page lists the plans.
