Twilio : Sending SMS messages

Watch out for

Twilio has strict rate limits on outbound messages so implement a delay or queue system to avoid temporary bans.
Google Apps Script execution time is limited to six minutes per run so process rows in small batches rather than all at once.
Hardcoding credentials in the script exposes your Twilio account so use PropertiesService to store secrets securely.
Phone number formatting must be E.164 compliant or Twilio will reject the request so add validation before sending.
