## AI overview

Resend Inboxes provides shared email addresses on your domains, grouping messages into threads that apps, teams, and agents can access. People and agents can work side by side; teams can assign conversations, leave notes, and continue one another's work. The API supports listing conversations and replying in the same thread, reusing its subject when none is supplied. Agents can connect through MCP or skills and be managed through the API, CLI, or MCP server. Built-in agents can create dynamic views or handle routine email work triggered by webhooks. You set their instructions, tone, and permitted actions, which include drafting replies, forwarding, labeling, assigning, marking spam, archiving, and deleting. The text recommends starting with limited permissions and expanding them as trust grows, while keeping the team in control. Up to three inboxes are free; additional inboxes cost $1 each on paid plans.
