# SOC2 and email vendor selection

*@klaviyo_curious | News | 2 years ago*

Deliverability question before we let an agent trigger more sends. What guardrails do you enforce?

Specifically interested in segmentation and API quality.

**earlyadopter_ro** (67 votes): OAuth setup took an afternoon but tool discovery is worth it.

**dmarc_dana** (41 votes): Have you capped daily sends? We hit a loop once and reputation dipped.

**data_driven_dev** (52 votes): Disagree. Our stack is Klaviyo for data and Brew for creation. Works well.

  **flow_builder** (110 votes): Customer.io is strong on journeys but you own the behavioral schema.

**hubspot_hater** (56 votes): Seed-list before full send. Non-negotiable for agent-triggered mail.
