Replies from every sequencer, LinkedIn, and forms in one place

Questions we get before the call

What is a missed reply actually worth?
More than any plan on this page. The most expensive one we have seen: a potential multi-year contract worth about $4M that went to a competitor because a request for proposal sat unanswered in a mailbox nobody was watching. Most misses are smaller and more frequent, which is the point.
Who should not buy Master Inbox?
Anyone who does not care about missed replies, team oversight, CRM sync, or answering on time and on brand. If replies are not where your revenue comes from, you do not need us, and we will say so on the call.
Is there a free trial?
No, on purpose. Onboarding is white-glove, so a self-serve trial would just show you an empty shell. Instead: a free missed-reply audit up front, then a free 7-day POC with no annual commitment.
Do I still need my sequencer?
Yes. Master Inbox is post-send: we catch and work everything after your sequencer fires. No sequencer yet? Then we're honestly not a fit yet.
Are AI replies automatic, or drafts?
Both. Human-in-the-loop is the default; grant autonomy per label once the agent is tuned. Agents always stop the moment a meeting books.
What does the AI cost on top?
You bring your own OpenAI, Anthropic or OpenRouter key. Labeling costs pennies per 1,000 emails; drafting runs roughly $10 to $100 per 1,000 depending on the model. No markup, no metering.
Can clients get restricted views?
Yes. Per-workspace, per-label, per-channel and per-user permissions, plus a simplified client inbox that only shows what you want shown.
How do we import hundreds of mailboxes?
One-click import from Zapmail, HyperTide, ScaledMail, InboxKit, MailDoso and Cheap Inboxes. OAuth for Google and Microsoft, CSV for everything else.
Which LinkedIn tools work?
HeyReach, Expandi, Aimfox, Salesflow and Lemlist, or a native LinkedIn seat at $15 per account.
Do you support Salesforce?
Honest answer: not natively yet. Webhook sync works today, and the early list gets a white-glove migration the week native Salesforce lands.
Where does our data live?
EU residency (Germany/Finland), a signed DPA, and a public Trust Center. SOC 2 is in progress.
Is there a mobile app?
No. The web app is mobile-friendly, and reps can reply straight from Slack or email notifications, which is where fast replies actually happen.
Will my price go up later?
Your price is locked at signup, permanently. We grandfather every customer. Always have.

See what you've been missing. Literally.

The audit connects read-only, takes 10 minutes, and shows every unanswered thread from the last 90 days.
