Every reply. Every client. One place

The Inbox Built for Lead Gen Agencies.

Your current tools are sending at scale but they’re missing replies.
Master Inbox catches what they don’t, so you never lose a lead again.

Managing 100, 500, or even 2,000 client inboxes is chaotic.

Your team wastes hours jumping between accounts, chasing replies, and updating sheets. Master Inbox centralizes every campaign response so you stay organized, responsive, and in control.
