In the MarketingSherpa Email Marketing Benchmark Report, 79% of marketers found delivering highly relevant content to be an either somewhat or very significant challenge.
When you break down email relevancy to its core components, it is essentially a combination of:
- Getting the right message …
- To the right person …
- At the right time.
While we often write about email messaging on the MarketingExperiments blog, today we’ll focus on that last element of relevancy – timing – in the following experiment with a MECLABS Research Partner …
EXPERIMENT
Background: A large financial institution offering a financial service requiring an application to consumers
Goal: To increase the number of completed applications
Primary Research Question: Of the send times tested, which time will result in the highest rate of completed applications from delivered emails?
“We conducted some research on the best times to send email, and the test was intended to see when current customers were more likely to complete an action,” said Ashley Hanania, Senior Research Manager, MECLABS.
EXPERIMENT DESIGN

The test had a total of 14 treatment paths. Each path had the same subject line, email body copy and design.
The only treatment value that was tested was send time. Two emails were sent each day of the week, one at 3:00 a.m. EST and one at 3:00 p.m. EST. The recipients were all in U.S. time zones.
“We tested 3 a.m. EST because the email would be first in your inbox, regardless of where you lived,” Ashley said. “This was also taken into consideration for the 3 p.m. EST send, because every recipient would be in the same mindset, afternoon work/weekend activities, as opposed to a 6 p.m. EST send, where the East Coast would be making their commute back home and the West Coast would still be at work.”
