On Friday night 19-2 1 what is the highest SMS open rate?

If you want to find the time period with the highest SMS opening rate, you can combine your working hours.

It's usually between 5: 30 pm and 7: 00 pm, which is the peak period. Most of the means of transportation during this period are subways, buses or taxis, and some will drive home. Under such circumstances, there are many people who have leisure time to listen to music and brush their mobile phones, so the reading rate of short messages is relatively high.

Dinner time is usually from 7: 00 pm to 9: 00 pm, so my suggestion is that you can submit the message at 6: 00 pm and make sure to receive it before 7: 00 pm.
