What should I pay attention to when sending short messages in groups?

SMS group sending is divided into four parts, namely platform, content, time and customer number. Generally, the content is charged within 70 words, and if it exceeds 70 words, it is a long message, and the long message is charged at 67 words. It's a bit circuitous for others to have time to read your content as much as possible, but for good reason. The number of customers is very important, whether it is sent to the accurate customer base directly affects the effect, and the platform is of course also very important. No matter how good the number is, no matter how good the content is, it's all a cloud if the text message is not received. Find a reliable platform, such as Haoyu Information Chain, 236, Chuangda and so on. Nothing else.
