Why is it that the best results for email are seen in the p.m., but the vast majority are sent in a.m.? Performance is everything. As a marketer, when you launch an email campaign, you try to focus on all the elements that could make it a success--or a failure: subject line. length, offer, creativity, images, and so on. One factor that usually gets the most attention is: When do we send?

email as social media

Conventional wisdom has long held that early in the day, when people are fresh and at work, is the best for performance (open rates and clickthroughs). But new research from Experian shows that while a.m. is by far the most popular time to send out that email, p.m. is better in terms of performance--far better. While performance will obvious vary by industry and other factors, in general, later--much later--is better. Between 8 p.m. and midnight, the open rate is more than 30% higher; and the clickthrough rate is almost 80% higher than their early-to-rise counterparts.

The reason? While open for debate, it seems rather straightforward that people have more time in the evening, to not only to spend time online, but to engage. The Internet, like a good nightclub, is a place to go for action after dark.
