Why does the fail rate become high if we send the template message in batch?
Your WhatsApp server could be disconnected if your server is sending many messages in a short period of time.
Please note the message limit of our basic public server is 4.0 msg per second for each number.
We could upgrade your client status to an enterprise license with a dedicated cloud server hosting and higher messaging limit if requested. Please submit a ticket to contact Stella Support for the inquiry.
