A price per 1,000 is only one part of an order. Check the minimum quantity, supported target, delivery conditions and refill eligibility together. A cheaper service may have different limits or no after-sales refill.

Start with the exact content you want to submit. A profile service and a post service may require different links. Read the description before funding an order, and retain the order record so support can investigate a mismatch.

Delivery counts do not prove audience interest or business results. Assess a service against its stated deliverable, and measure meaningful outcomes separately.
