Message Delivery Time in Channels (TTL)
Last updated: 1 June 2026
For each channel, the operator or provider sets a default message lifetime (TTL—Time To Live)—the period during which a message can be delivered to the recipient after it is sent.

From 30 seconds to 30 days (720 hours), depending on the message's Time To Live (TTL) specified in the message template.

- If the cascade's TTL is set to a value shorter than the template's TTL and the message is not delivered within the cascade's TTL, the cascade proceeds to the next step. By default, Meta will continue attempting to deliver this message to WhatsApp until the template TTL expires.
- If the TTL set in the cascade is greater than the template TTL and the message is not delivered within the template TTL, Meta stops delivery attempts, and the cascade proceeds to the next step after the template TTL expires.
