Assumptions
This calculator is an illustrative planning model, not a pricing quote or performance guarantee.
Advanced assumptions are editable so the comparison can match your sales motion.
Email-only cost estimates SDR capacity and fully loaded SDR cost, not software spend alone.
Letr cost per meeting uses modeled campaign spend: platform assumption plus unit cost per letter.
Pipeline is potential qualified pipeline, not guaranteed revenue.
