The SMS log shows every message your workspace has sent or received, live — queued, sent, delivered, or failed, with the carrier's failure reason when there is one. Billing is per segment: 160 GSM-7 characters fit one segment (153 each when a message spans several); Unicode messages fit 70/67. The composer shows the segment count as you type.

Marketing SMS is held to a stricter bar than email: the recipient must have prior express consent on record, and sends respect recipient-local quiet hours (a marketing message queued at midnight is deferred to the morning window, never dropped and never sent at 2am). Transactional messages — receipts, alerts, verification codes — are not window-gated.
