Reply.io

Reply.io sends the campaigns but misses forwards and new-address replies. Master Inbox catches every Reply.io reply, tags it, and syncs it to your CRM.

How Reply.io works with Master Inbox

Reply.io runs sales engagement across email, LinkedIn, calls, and SMS, with an AI SDR on top. Running that many channels means replies come back in that many places, and the ones that matter get buried. Master Inbox unifies them: every Reply.io response, across every channel and mailbox, threaded per prospect and tagged the second it lands, so your reps work one queue instead of five and answer the interested leads first.

What you can do

  • See every Reply.io reply in one inbox, not campaign by campaign or account by account
  • AI-tag each reply as it lands: interested, objection, OOO, referral, asked-for-pricing
  • Catch the forwards and out-of-office replies Reply.io drops into an untracked folder
  • Mark interested leads do-not-contact in Reply.io so you stop emailing buyers

Why it matters for outbound revenue teams

Reply.io is built to send, and it's good at it. But the replies, where deals are actually won, get scattered and missed. Master Inbox is the reply layer that turns your Reply.io spend into worked, tracked, closed conversations.

My favorite thing is that you’re catching untracked replies, because I know we missed out on deals.
