When several people handle incoming email, shared inbox software can help organize ownership and coordinate replies. Compared on assignment automation and collision detection, the options also differ in internal comments, supported mail platforms, and shared mailboxes. Mobile apps, free plans, and paid-from pricing add further criteria to check. Help Scout, Zoho TeamInbox, and Cerb are among the entries, with Drag and Hiver also listed. Consider how your team assigns conversations and avoids overlapping responses, and whether members need to access shared mail from mobile apps.
30 shared inbox software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
