How to send marketing information to India?

There are two ways, one is to find an international SMS platform; One is to send it on your own mobile phone, but it is easy to be judged as harassment if it is sent too much.

Users don't hate marketing messages sent by some enterprises, but hate marketing harassment that has nothing to do with them! Although the information itself is valuable, it does not exist for inappropriate customers, so before sending marketing information to Mexico, we must first find "demanding" customers.
