Hiver runs your support inbox. Master Inbox runs your outbound replies.
Hiver is a strong omnichannel help desk and shared inbox for teams on Gmail, Outlook and more. Cold outbound is a different job: replies from hundreds of sending mailboxes and LinkedIn accounts. Master Inbox is built for that job and works alongside Hiver.
Free 7-day POC. Unlimited users on every plan. Hiver stays your support inbox.
What is Hiver, really?
A shared inbox and help desk for service teams. Three things to know when you compare it with an outbound reply inbox.
Assignment, routing, tags, notes, shared drafts and collision detection, with SLAs, CSAT surveys and analytics on higher tiers, across email, chat, Slack, voice, SMS and WhatsApp.
Growth is $25, Pro $55 and Elite $85 per user per month on annual billing, or $35, $65 and $95 monthly, as of 28 October 2026.
Hiver's own pages cite support, customer success, inbound sales, finance and HR teams. It works with Gmail, Outlook and other providers.
If your team handles customer requests from a shared inbox, Hiver is built for that. Keep it, and add Master Inbox for outbound replies.
