Skip to main content SMS is the fast fallback when push/email are missed: if a message stays unread beyond your wait window, CometChat can send a concise text that brings users back to the conversation.
How it works
Trigger : Fires when a chat message remains unread past the wait window you set.
Templates : Keep payloads lightweight (sender, short snippet, optional deep link) in Templates & Sounds.
Preferences/DND : Honors per-user/per-conversation mutes, global DND, and quiet hours before sending.
Providers : Connect Twilio or a custom provider in the dashboard; CometChat handles fan-out.
Recipients : Store verified phone numbers via API and respect opt-in/opt-out for your region.
Observability : Use logs to confirm sends and diagnose delivery issues.
Key capabilities
Unread-based SMS nudges for 1:1 and group chats.
Template variables for sender and a short preview; optional deep links to reopen the chat.
Quiet hours, mutes, and DND enforcement to prevent spam.
Plays well with push/email as layered fallbacks.
