How to write the double 1 1 activity speech?

Double 1 1 activity speech: the text and content of short messages should not be too complicated and difficult to understand, and there should not be too many thresholds and preconditions. More than 80% people spend less than ten seconds reading short messages on average. The choice of SMS sending and SMS channel is particularly important.

The best way is to test directly, using A/B test method. SMS A/B test is to make two (A/B) or more (A/B/N) SMS versions and send them to the same (similar) group (target group) respectively. Then collect the relevant data and feedback of each group, send short messages through SUBMAIL, and generate visual analysis reports in real time. Through these data, feedback and email analysis reports, we can further know which way is better, so as to continuously improve and perfect the version with the best effect and the most suitable for the target population.
