Best Shared Inbox Software (2026)

Best Shared Inbox Software (2026)

Shared inbox software lets multiple people read, assign, and reply to emails from a single mailbox. No more forwarding messages or sharing passwords. Everyone works from the same inbox with clear ownership of each conversation.

A McKinsey survey found that workers spend 61% of their day managing email. Shared inbox software cuts that time by bringing messages, assignments, and collaboration into one place. Many platforms also include email ticketing, customer management, and knowledge base features.

If you rely on Outlook for support, learn about the problems with using Outlook as a helpdesk and why dedicated shared inbox software matters.

Below are 25 shared inbox software options. They are listed alphabetically and not ranked.
