SharedInbox is an email collaboration tool that brings shared inboxes into Slack. Teams can connect Gmail, Google Workspace, Outlook, Office 365, Microsoft 365, Yahoo, or other IMAP mailboxes to Slack channels, receive inbound emails in Slack, send new emails with /compose, and discuss or reply within the thread created for each email.
The product is not focused on traditional email blasts or marketing automation; its core value is “shared inbox + Slack collaboration.” Each inbound or outbound email creates a separate thread where team members can @ colleagues for discussion. Emails can also be assigned to owners, given statuses and due dates, and reviewed through task reports via /si tasks. It supports viewing attachments in Slack, custom signatures, and checking delivered/open status for emails. On the integration side, it covers Slack and common email services, and also supports IMAP access. However, the available material does not disclose an open API, webhooks, or more advanced developer capabilities.
Pricing is fairly straightforward: Go costs $9/month and includes 1 connected mailbox, 1,000 inbound messages/month, and 500MB of attachment storage; Starter costs $29/month and includes 5 connected mailboxes, 5,000 inbound messages/month, unlimited storage, and priority support; Business costs $79/month and includes 20 connected mailboxes and unlimited inbound messages. All plans include a 7-day free trial, unlimited team members, unlimited contacts, and unlimited outbound messages. Annual billing saves 2 months. In terms of performance, the official site only states that users can view delivery and open status, that alerts are sent when usage reaches 60% and 90%, and that inbound email reception stops once the limit is reached. It does not provide delivery rates, latency figures, or an SLA.
The main advantages are simple setup, a strong fit with Slack-based workflows, and pricing that does not charge per team member. It is well suited to customer support, sales, operations, and other teams that need multiple people to handle shared inboxes such as support@ or info@. The downsides are its heavy dependence on Slack—if Slack is not the team’s main workspace, its value drops—along with noticeable limits on lower-tier plans and relatively limited compliance and enterprise security materials.
The available material does not provide information about network accessibility from mainland China. Because the product depends on Slack, Stripe payments, and external email services, teams in China should test network connectivity, Slack availability, and credit card payment before adoption. If access is limited, alternatives include Front, Help Scout, Zendesk, Freshdesk, or domestic customer support ticketing systems.
