The Master Inbox where LinkedIn and email replies land together, labeled by intent per prospect
LinkedIn Inbox

Every LinkedIn conversation. One inbox. Next to the email.

SDRs run three accounts each, automation tools run more, and meeting requests hide in second replies nobody checks. Master Inbox pulls every LinkedIn conversation into one place, threaded with email per prospect.

Free 7-day POC. Unlimited users on every plan. Works with your LinkedIn tools or a native seat.

Whatever you send with, this is where the replies land

Master Inbox adds no automation to your accounts. It reads and sends through the tools you already run, using their own APIs.

HeyReach

Every conversation from every sender in a campaign, with the campaign and the sending account attached to each thread.

Expandi

Connection requests, accepts and message replies, threaded onto the prospect instead of sitting per campaign.

Aimfox

Replies across every managed profile, pulled into one queue your inbox managers can actually work.

Salesflow

Inbox messages and follow-up responses, labeled by intent the moment they arrive.

Native seats

For profiles that run no automation at all: connect the seat directly at $15 per account and its messages sync the same way. SalesRobot, LeadBird, Lemlist and GetSales connect too.

One prospect, both channels, one thread

The email reply and the LinkedIn reply from the same person stop being two conversations to reconcile.

Same prospect, one thread
Meeting Request

The meeting ask arrived on the channel nobody was watching, two days after the email. In one thread it is impossible to miss.

Short messages, real intent

LinkedIn replies are four words long. The label has to come from the thread above them, not the word count.

Not now

Acknowledged, nothing asked for. It drops out of the queue your reps work first, and back in when a follow-up lands.

Interested

Straight to the top of the queue, or to an agent that answers with the one-pager and offers two real times.

Information Request

Not a rejection, a request for context. It gets your intro, not a pitch, and stays on the same thread.

Custom labels

Teach the labels how LinkedIn actually talks

Labels are prompts you write, not a fixed list. Most teams keep one set for email and a looser one for LinkedIn, where a reply is rarely a full sentence.

  • Your labels, your wordingCreate any label and describe in plain language what belongs in it. Interested, referral, wrong person, competitor, whatever your team argues about.
  • Tuned per channelA LinkedIn "sure" and an email "sure, send it over" can score differently, because you wrote the rule for each.
  • Applied the second it landsLabels drive views, routing, agent autonomy, SLA reporting and CRM lead status. All of it runs off the label.

Questions we get

Which LinkedIn tools does it work with?
HeyReach, Expandi, Aimfox, Salesflow, SalesRobot, LeadBird, Lemlist, and GetSales, plus a native LinkedIn seat at $15 per account for profiles that don't run through a tool.
Can I see LinkedIn and email in one thread?
Yes. Conversations thread per prospect, so the LinkedIn exchange and the email exchange with the same person read as one conversation.
How many accounts can it handle?
Teams run dozens of automation seats and SDR profiles in one workspace. Views and permissions decide who sees which accounts.
Do LinkedIn replies sync to the CRM?
To HubSpot, yes, as native LinkedIn activities on the contact rather than notes. Other CRMs receive them by webhook.
Will this get my LinkedIn accounts restricted?
Master Inbox adds no automation to your accounts. It reads and sends through the tools you already run (HeyReach, Expandi, Aimfox and the rest) via their own APIs, so your exposure is exactly what it was before, minus the tab-switching.
Is my data safe? Where is it hosted?
Yes. Master Inbox is hosted in the EU, with data centers in Finland and Germany, built GDPR-compliant with DPAs available on request. See /security for details.
Can I keep clients' LinkedIn traffic separate?
Yes. Each client's accounts live in their own workspace with scoped permissions, so an inbox manager sees only the clients they run.
Can reply agents answer LinkedIn messages?
Yes, with the same human-in-the-loop controls, testing, and calendar booking as email replies.
