Some messaging channels have a limited messaging window for the contact to receive a response. The messaging window refreshes every time a message is received from a contact. Refer to the following channel and their respective messaging window:

Facebook Messenger's Messaging Window is now extended to 7 days because ISMessenger platform has been selected to participate in Facebook HUMAN_AGENT tag Closed Beta program.
The 24-hour messaging window is only applicable to WhatsApp Partner API channels; Twilio, Vonage, MessageBird & 360Dialog. WhatsApp Chat API does not have this limitation as it is not a WhatsApp Partner.
Messages can still be sent outside the messaging window but it will not be delivered. There will be a red exclamation mark indicating the message is not delivered along with an error message.
For Facebook Messenger and WhatsApp, they have a feature that allows users to send a message to the contacts beyond the messaging window.
To send a message to Facebook contacts after the messaging window, you can use Facebook Messenger Message Tag to do so. For more information on, look at Facebook Messenger Message Tag.
To send a message to WhatsApp contacts after the messaging window, you can use WhatsApp Message Templates to do so. For more information on, look at WhatsApp Message Templates.
In IS Messanger, you may broadcast content to your contacts if the channel is supported. However, there may be a few limitations that need to be considered when broadcasting with a supported channel.
Bear in mind that every channel has its own rate limit of how many requests/messages can be processed in a time interval. This may affect the deliverability of the broadcast content to your contact.
If you wish to broadcast to contacts from WhatsApp API Channels (Twilio, MessageBird, Vonage, 360dialog), you will need to specify a WhatsApp Message Template as the broadcast content.
Before broadcasting to these contacts, please make sure your WhatsApp Message Template is submitted and approved by WhatsApp.
As for Facebook Messenger, you can specify the content in the broadcast dialog but a Facebook Tag is needed to send the broadcast content.
When using Facebook Tag for broadcast, please make sure you comply with Facebook's Messaging Policy to prevent your Facebook page being banned from sending messages.
A rate limit is the number of API calls an app or user can make within a given time period defined by the channel. For example, a rate limit of 30 requests per second means that in one second, any request that comes after the 30th request will be throttled and fail.
In the context of IS-Messenger, a request is when a message is being sent to a contact
