An analysis recently conducted by technology firm Responsys, put Thursday as the best day for email marketing campaigns. It also confirms what we already knew: Monday and Friday are not good days to send out campaigns.
The company analysed what it said were a total of one billion email marketing messages, sent by 350 marketers in Australia.
Thursday was narrowly the day that delivered the highest open rate for emails, of around 22%. It is also the day when the most emails are sent. However, the day that delivers the highest clickthroughs once an email has been opened is Tuesday, with about a 9% clickthrough.
Excluding the weekend, the days delivering the worst open rate are Mondays and Fridays. Friday also delivers the lowest clickthrough rate.
