Signed-in agents.
OAuth sign-in for every agent, checked against your workspace access and revocable from the Agents page.
Sellbird lets an AI agent do outreach work without handing it your inbox or your card. Your agent works through Sellbird's tools; campaign drafts need review by default, reply drafts always need review, and purchases require your approval. Only a workspace owner can turn on campaign autopilot. Workspaces are separated in the database itself, and every recipient can opt out in one click.
The tools your agent can call simply cannot approve an email, buy a domain, change DNS on your own domain, raise a cap or resume sending. They create a request; the dashboard shows it to you with the button.
Every campaign email waits for your approval by default. A workspace owner can turn on autopilot in settings, and then campaign emails send without one-by-one approval, still inside your sending limits and opt-out rules. Reply drafts always need your approval. Your agent can never turn on autopilot, approve a draft or approve a purchase.

Row-level security in the database keeps each workspace's data to itself.
One-click unsubscribe on every cold email, and a suppression list that applies at once.
Sending pauses itself before bounces damage your domains.
Your agent never gets your mailbox password. It can read the workspace contacts and conversations you allow through MCP, so your AI provider may process that content. Every campaign email waits for your approval by default.

At the database level. Row-level security means a request for one workspace can’t read another’s data, even if the application asked for it.
Revoke its connection on the Agents page and it stops at once, or use the switch that stops every agent in a workspace. Each connection also has its own rate limits.
Every cold email has a one-click unsubscribe and an opt-out footer, opt-outs are suppressed across the workspace at once, and sending pauses itself when bounces climb.
