eROI Days Email Agency

It’s time again for the eROI quarterly email study on deliverability. The eROI, Q4 ’05 email study breaks down, by list size, which day is the best day for email campaigns. In general terms the Study indicates a 29 percent drop quarter over quarter in read rates, and a 21 percent drop in click rates in Q4 over Q3 2005. Additionally, the Q4 data shows a similar trend from the third quarter in that the noticeable high point in the week occurs on Friday for both reads and clicks. So, from this quarter eROI reaffirms that sending volume is inversely related to how reads and clicks react.

For Q4 eROI sees similarities to last quarter with read and click rates generally declining as list size increases, but there are some major differences. Read rates are much more erratic between 500 and 10,000 emails. Click rates see a more consistent behavior and do not decline in nearly as consistent of a pattern as last quarter. Volume for 250,000+ lists takes a huge jump upward resulting in approximately 20 percent read rate. We believe this goes to show, segmentation works and the general B2C marketer really needs to adopt more targeted mailing campaigns. B2B mailers are starting to adopt them more and more.
