Messaging Window
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:

7 Days | |
48 Hours | |
Viber | 24 Hours |
Google Business Messages | 30 Days |
For WeChat and Instagram, 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 Viber, messages sent by the bot outside the messaging window will be considered Chatbot-initiated Messages. You'll get an error message with a red exclamation mark on the platform once you've exceeded the monthly free limit.

For Facebook Messenger and WhatsApp, they have a feature that allows users to send a message to the contacts beyond the messaging window.


Broadcast
In respond.io, 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.
WhatsApp API Channels
If you wish to broadcast to contacts from WhatsApp API Channels, 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.
Facebook Messenger
As for Facebook Messenger, you can specify the content in the broadcast dialog but a Facebook Tag is needed to send the broadcast content.
Rate Limits
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.
