The use of email to communicate marketing and operational messages is on the increase. Your customer’s inbox is flooded with marketers hoping to catch their attention.

eMarketer reports that email volume in the United States is projected to nearly double from 1.5 trillion in 2003, to 2.7 trillion in 2007. This massive growth means you have to work harder to get your message read.

There are a number of ways in which you can manipulate how many people engage with your emails, one of which is to send your communication on the day which promises the highest read rate or the best click rate.
