Our WhatsApp solution can support 50 requests per second with bursts allowed up to 150 requests per second, as this is a paid commercial and official channel connected directly to Facebook servers. Each message sent will return delivery status such as read or failed.
Telegram is a free service and hence there are actually no performance guarantees. However, our system can post a message to a private Telegram channel. You recipients will be provided the link to subscribe to this private channel. When there is an activation broadcast, a generic alert will be posted to the private Telegram channel asking recipients to refer to their SMS, WhatsApp or IVR message that is currently being triggered.
