Collaborative inbox and email management for teams
Let multiple people work the same inbox with clear assignment, internal statuses, and visibility into who is answering what.
Discuss and prepare replies inside the email thread itself, so context stays attached and nobody is left out of the loop.
Turn any email into an assigned task and see what each teammate is working on today, tomorrow, and next week.
Automate repetitive routing, tagging, and follow-up with rules, rule templates, and workflow automations.
Open-source AI gateway with observability and evals built in
Route to OpenAI, Anthropic, Google, xAI, DeepSeek, Qwen and many other models through a single API key and one OpenAI-compatible endpoint.
Keep your existing OpenAI, Anthropic, LangChain or Vercel AI SDK code and change only the base URL.
Automatic fallbacks, retries and load balancing across providers and API keys keep requests answering when a single provider rate-limits or fails.
Every call is logged and traceable, with evaluation tooling and a CLI so you can query logs and traces from your terminal.
One API key for hundreds of AI models from every major provider
Delivers blazing-fast keyboard-driven email management, but lacks Missive's team-first shared inboxes and built-in internal chat channels.
