What is MasterInbox?
MasterInbox is a dedicated tool for centralizing replies from cold email campaigns. Like Hothawk, it pulls replies from all your sending inboxes into one place.
The goal: stop checking dozens of inboxes manually and manage all replies from a single dashboard.
Key Features
Unified Reply Dashboard All replies from all connected inboxes in one view.
Multi-Account Support Connect inboxes from any provider.

- Agency: $499/month (3,000 mailboxes, 30 workspaces, HeyReach/Expandi integrations)
- Unlimited 30k: $1,297/month (unlimited everything, HubSpot, API access)
More expensive than Hothawk at comparable mailbox counts, but includes AI reply agents and LinkedIn tool integrations on higher tiers.
