There are more and more studies being done to test which day is best to send emails, and a new report this week confirms what we pretty much already knew….it pays to test!

There are a couple of interesting findings in this report….most interesting is the fact that Sunday may actually be a good day to send emails. This is obviously only true for Consumer targeted emails, but in the past Sunday hasn’t been a very good day…so add another day to the testing.

Also noteworthy is the fact that it may pay off to focus on finding an unpopular time to send emails. You may find open rates are lower, but click-thru and conversions might actually be higher since the recipients receive fewer emails….and therefore have more time to read the emails they do receive.

There are many factors that will determine which days are best to send, and it may even be true that different days are good for different types of emails from the same company. The key again is to test, and be flexible…..and don’t stick with what used to work as a rule. Email is still evolving, and is very much in flux, so expect delivery day success to change right along with everything else.
