Dan Zarrella recently hosted the Science of Email Marketing webinar, view slides and video here. His findings were the result of analyzing over 9.5 billion emails in a recent research project. One common question covered in the research is coincidentally something clients always ask…”What is the effect of time-of-day on click rates OR unsubscribe rate?” See the graphs below for details on this controversial topic. You can note the 3-4pm lull when most consumers are LESS likely to react to an email. On the flip side, the early morning 5AM-6AM time slots saw a high spike.
It should be noted that there is no right OR wrong time of day but you can use this research as a starting point to test what works for your industry, product, offer, and brand.
