Hello. We rather upset a new customer of ours by sending a rewards balance email out at 2am. I can only assume by the tone of their email that it awoke them on the wrong side of their bed.
Could we look at the timing of certain automated emails? Rewards balance emails at 2am like in this case have the effect of "Block delete won’t use ever again return order when arrives". A more effective time could be 11am-3pm whilst on an extended lunch break or 6pm - 9pm after the kids are fed!
Order emails and the like, triggered by customer activity, at 2am make sense if that's when they're shopping of course.
