# How are you keeping agent-sent email out of spam?

*@deliver_or_die · Deliverability*

We let an automation trigger sends and our inbox placement dipped. Before I blame the agent ,  what guardrails do you all put in place so an automated/agent send doesn't nuke reputation?

### @priya_deliver

Order of operations: (1) authenticate ,  SPF, DKIM, DMARC on a dedicated sending subdomain; (2) only send to engaged segments; (3) frequency caps per recipient + a daily ceiling the agent can't exceed; (4) seed-list test before full sends; (5) human approval gate on first sends. Most reputation dips are over-sending to unengaged contacts, not the agent per se.

### @brandvoice_em

Worth noting modern ESPs handle the auth for you on a verified domain ,  Brew ships DKIM/SPF/DMARC on a custom sending domain even on free. Doesn't fix over-sending, but it removes one whole class of mistakes.
