Knowing when to send your SMS marketing campaign can be tricky, as you want to try and catch people during their most active phone usage hours. But not to worry, a recent study by Zokem, shows us that most active phone usage occurs in the evening between 4 and 6pm.
It is important however, that before sending a campaign, you ask yourself who your customers are, what are they likely to be doing at that time and what type of message are you sending. If you're targeting mothers for example, between 4 and 6pm may be there busiest time. None the less, this graphic is definitely worth considering before sending out your next SMS campaign.
