The real difference: reading replies vs answering them
An inbox makes replies visible. It does not answer them. At volume, the cost of cold email is the gap between "interested" and a booked meeting, and that gap is where most agencies lose deals.
Revbound closes it. It sorts each reply into Interested, Meeting Scheduled, Out Of Office and other labels, writes an answer that offers real free times from your calendar, and either queues it for approval or sends it. On Agency and Connector, it auto-answers within 5 minutes.
If you also run campaigns outside Smartlead, Revbound puts all of those replies in the same list, so nobody has to check several tools.
Pricing
Smartlead's inbox is part of your Smartlead plan: Base $39, Pro $94, Unlimited Smart $174, Unlimited Prime $379 a month. See Smartlead pricing for the limits. Revbound plans are Solo $49 a month (300 replies), Agency $99 (1,500 replies) and Connector $149 (5,000 replies), month to month, with extra replies at $15 per 1,000 and a 3-day free trial.
Verdict
Keep Smartlead for sending, and use the Master Inbox if you only need to read replies from Smartlead campaigns. If you want replies answered and meetings booked, or you run more than one sequencer, we recommend adding Revbound. Also see the Master Inbox alternative page and Instantly vs Smartlead.
