Validation gate
Your rules check every send
Sender info, look-alike domains, urgency or credential bait, redirect hops — a pass sends, a refusal stops right there, an unclear case waits for a human.
Agents thatsendyour email.
Campaigns and transactional mail, sent by agents inside the scope you approved. Every send passes the validation gate before anything leaves.

- Scopes, templates and suppression lists stay put — zero re-setup per agent
- Works with Claude Code, Codex, Cursor and whatever ships next
- Pilot a new agent on one campaign, then roll it out

Checked before it leaves
Nothing ships unchecked
Content rules, every link hop and quiet hours run before a single message goes out. Fail a check and nothing leaves.
Get startedNo mail keys in the agent
Agents never hold your keys
The agent gets a scoped, device-approved credential that expires in 24 hours — never the SMTP or provider key. Revoke once and everything it held stops working.

No. There is no payment scope for agents; a person tops up in the console, and auto-recharge runs only inside a monthly cap you set.
