Master Inbox is the router in the middle

Reply.io is an AI-powered multichannel sales engagement platform, email, LinkedIn, calls, and SMS. Attio is a modern, flexible CRM teams build into the exact workflow they want. The gap is the replies: they scatter across mailboxes, and getting them into Attio means a rep copying threads by hand, if they remember at all. Master Inbox is the router in the middle. It catches every reply from Reply.io, including the forwards and out-of-office Reply.io never surfaces, tags it by intent, and syncs the contact, conversation, and stage straight into Attio. Reps work one inbox; Attio fills itself with warm leads.

  • Interested replies mapped to the right Attio stage automatically

Why it matters for outbound revenue teams

The Reply.io-to-Attio handoff is where outbound revenue leaks: a hot reply that never makes Attio is a deal you already paid for and lost. With Master Inbox in the middle, every Reply.io reply lands in Attio in seconds, with context.

In an ideal scenario, fully integrated with our CRM, which is the tricky part. We use Attio.
