Channel · SMSHandled by Pulsar
Still the one that always gets seen.
SMS has no algorithm and almost universal reach, which makes it the right fallback for a customer who has not opened WhatsApp in three days — and for anything genuinely time-sensitive.

On this channel, specifically.
Fallback when a WhatsApp or email thread goes quiet
Time-sensitive alerts, confirmations and reminders
Replies routed back into the same conversation thread
Best as a fallback and for time-sensitive messages rather than as a primary channel. Used badly, SMS reads as spam faster than anything else.
