## Choose the check that fits the campaign

Transactional SMS programmes usually start with number validation. Conversational or rich-media campaigns benefit from channel checks, so you route each contact to the channel where they are present.

## Availability by market

Channel coverage depends on the market and on the channel itself. Availability is shown in the app before you submit a job; services that are not enabled for your account are not billable.

> Results describe the technical status detected at the moment of the check. They are not marketing consent and do not guarantee message delivery.
