Primary Operational Bottleneck: Mailbox Deliverability Degradation: High-volume autonomous outbound generation introduces mailbox domain reputation risks if DNS authentication records and programmatic sending pacing lack strict manual governance.

Walk-Away Rule: Walk away if your organization lacks secondary domain infrastructure to safeguard primary corporate email deliverability against high-volume automated outbound sequences.

Negotiation Lever: Incorporate SLA-backed termination rights or credit remedies tied to CRM bi-directional synchronization reliability and message classification error thresholds.

Negotiation Lever: Demand a monthly billing schedule with a 30-day cancellation clause on the $900 Explore tier instead of the standard mandatory quarterly advance payment.
