The average email open rate climbs gradually after sending for about 24 hours. The average SMS open rate spikes, with 70% of opens happening in the first 60 minutes.
This immediacy allows for triggered SMS messages. For example, if you have a regular customer over a period of time, and they stop coming into your store, you can send them a text with deals to get them to come back.
These messages can be triggered by any action (or inaction) by the customer, from not coming to visit your ecommerce shop to buying a particular product. These triggered messages are also great ways to ask for feedback from your customers. If they make a 5th visit this month, you can present them with a survey to learn more about your VIPs.
