E-mail marketing campaigns sent out on a Wednesday are more successful than those sent on other days of the week, according to newly published data.

Statistics from e-marketing enabler Emailcenter UK shows most British electronic marketers (almost 25%) deliver e-mails on Thursdays.

But, despite the majority view, more recipients opened the messages on a Wednesday, while click-through rates were also higher than at any other time in the week.

"The theory behind this is perhaps people have more time on a Wednesday," according to a post on the Emailcenter UK blog.

"Less people are on holiday and away from their work email, while consumers are presumably not enjoying a night out on a work day."

The research methodology was not disclosed. The company claims over 300 corporate clients including Andrew and P&O.

It said the findings were "surprising". The data also showed more clicks are made from emails on a Friday.

Just to say as author of this piece the research was carried out based upon email campaigns sent by Emailcenter clients in the last 6 months. Sample size is just under 4500 email campaigns. Text only emails were excluded as you cannot track open rates in these emails. The sample size on Saturday and Sunday was so small we decided to exclude these from the results as we felt the data was not reliable.

The research has also collected and analysed the times of the day emails are sent. We also tagged an industry sector against each email campaign so we will be showing how results and trends differ for each sector.
