Preview Sms Announcement
preview_sms_announcementPrepare the exact SMS body and eligible audience for host review. Use a separate brief message (usually <=160 characters), not the full email. Host introduction, event link and STOP footer are added automatically. The complete text must fit three SMS segments. Returns body, audienceSize, previewId and expiry; nothing is sent. Show these before send_sms_announcement.
