I am developing an application in which i need to send 100+ of messages. After going through few threads i came to know there is limitation on sending messages like 100 messages can be send in an hour. To do so i divide my recipient list into chunks and place delay of 5 seconds between each chunk and 3 seconds delay in every message. The delay between chunks increase after every chunk and when it gets to 100 seconds it will reset to 5 seconds. After that it worked OK for 50 messages but when i raise recipient list it causing issues some messages didn't go at first place and shown as error messages in native.
Is there any standard way to achieve this i may need to send 100+ messages , how can i send multiple messages without any failure at once. If i need to place delay what should be the appropriate delay between chunks or messages.
Thanks in advance.
