Rules your agent can't talk its way around.
Every send is checked before it leaves: duplicates, cooldowns, suppressions and daily limits. Your agent can tighten these rules. Only a person can loosen them.
No double sends.
A dedupe key is only ever sent once. The same template to the same person from the same mailbox waits out a cooldown, 10 minutes unless you change it. Replies inside a thread skip the cooldown, so conversations aren't throttled.

A hard bounce or a spam complaint suppresses the address at once, and three soft bounces in 30 days do the same. You can suppress a whole domain too. Every agent on your account works from the same list.

Every block says why.
A blocked send comes back as a result, not an error, with the rule that stopped it. Your agent can wait, pick another contact or ask you.

It can tighten a rule, never loosen one.
An agent can lengthen the cooldown, pause a mailbox or lower its autonomy. Shortening the cooldown, resuming a mailbox or turning off injection quarantine gets a 403 and a link for a person to decide.

Rules match a new thread by sender domain, sender address or subject, then move it to a folder or archive it. They run in the order you set, and the first match wins unless a rule lets the next one run.
