Overview
Description

Missive is an email client built for teams rather than individuals. Shared inboxes let multiple people see, discuss, and respond to the same email account, with internal comment threads on each email so teammates can coordinate without forwarding messages back and forth. Emails can be converted into trackable tasks, tagged for follow-up, and assigned to teammates, while dedicated team spaces keep different departments or accounts organized. Missive also connects email, SMS, and social messages into one inbox, with 25+ integrations and an AI assistant that can help draft replies and gather context via MCP.

Shortwave is an AI-powered email client built by former Google engineers that layers natural-language automation on top of email. Users can ask it to organize their inbox, draft messages in their own voice, search across past mail, and schedule meetings, all through plain-language prompts rather than manual filters. Beyond individual productivity, Shortwave includes team features such as shared threads, comments and assignments, plus integrations with Slack, Notion, Asana and HubSpot. It is used by teams at companies including Twilio, Spotify and GitHub, and runs on Mac, Windows, iOS and Android in addition to the web.

Pros & Cons
Pros
  • Genuinely collaborative email, not just a shared login to one inbox
  • Email-to-task conversion removes the need for a separate ticketing tool for many small teams
  • 30-day free trial with no credit card required
  • Strong customer ratings (4.8 on G2 with 1,000+ reviews)
  • Full native apps across Mac, Windows, iOS and Android, not just a browser extension
  • Team features like shared threads and assignments make it usable for shared inboxes
  • AI search can answer questions across mail history rather than only keyword matching
  • Built by an experienced team with backing evident from its enterprise customer list
Cons
  • No permanent free tier, subscription required after the 30-day trial
  • Per-user pricing can add up for larger teams
  • Primarily an email/messaging tool, not a full help-desk replacement for complex support workflows
  • No published free tier, only a 14-day trial before paid billing
  • Per-seat pricing rises quickly at the Premier and Max tiers for AI-heavy usage
  • Migrating a team's whole workflow to a new email client is a bigger switch than adding a plugin
