Coherence vs UnInbox

Coherence is a customer operations platform connecting CRM data, communications, workflows, websites, campaigns, and AI agents. Its Shared Inbox gives sales, support, and operations a common place to handle incoming conversations with customer context, replies, and internal discussion. Teams can assign conversation ownership, add internal notes, view teammate presence, and work on shared drafts. Inbox categories, custom fields, rules, assignment settings, response targets, snoozes, and reminders help organize queues. Staff can select published Knowledge articles and review suggested replies with source references, then edit drafts before sending; AI generation uses the workspace's configured AI provider. Shared Inbox is available on Pro, Team, and Enterprise. Listed integrations include two-way Gmail or Outlook email sync, Google or Microsoft Calendar sync, and a REST API. Coherence says data is encrypted at rest with AES-256 and in transit with TLS 1.2 or higher, and stored in the United States. The service is not currently available in the EEA, UK, Switzerland, Australia, Canada, and several other regions. Pro costs $29 a month per user; Team requires at least 10 paid seats.

UnInbox is collaborative email software for teams and professionals. It provides shared inboxes, shared spaces, and workflow statuses so teammates can comment on conversations, reply from shared addresses, and see whether work is complete. Users can add unlimited addresses, including admin@, support@, sales@, and billing@ examples. The codebase is open source, with instructions for running it locally; self-hosting requires additional manual email configuration and production guidance through Discord. A free plan costs nothing @uninbox.me email address and includes personal spaces, three workflows per space, seven-day raw email retention, and community or email support. Pro costs $12 a month billed per user, adding teams, unlimited custom domains, shared and public spaces, SMTP and API access, assignees, and priority support. Enterprise has no listed price, requires 30 users, and adds dedicated infrastructure, SAML SSO, long retention, onboarding, and organization-wide video support.
