Before you choose
Confirm any signup or recipient restrictions and request production new-contact and throughput limits. Unlimited messages on a plan page is not a complete capacity specification. During a supported evaluation, inspect webhook authenticity, duplicate events and channel reporting. This entry identifies the published test surface, not measured success at processing an application’s real customer traffic.
