# Prepare SMS Newsletter Dispatch

Prepares SMS newsletter dispatch by checking text, sender and provider, estimating recipients and returning the KlickTipp dialog for a logged-in person to send now or schedule. This call sends nothing. Each recipient costs SMS credits and sent messages cannot be recalled; say so when handing over the link.

## Input schema:
