So when should I send out my newsletter?

Since email time immemorial there has been great debate about timing. What day to send, what time to send?

Statistics are studied, theories evolved. Results change, and consequently so do timings.
Timing strategies often depend upon your database; is it primarily composed of business users, or weekend users?

Some rules do apply to all deployments – from Friday lunchtime through to Monday lunchtime, don’t bother sending – unless your message is time sensitive and critical to an event during that period. After hours emails in midweek are usually a waste of time, as well.

I believe that the most important timing rule is consistency. By deploying at the same time of the same day each week or month, you can gradually create an event – one that will be anticipated, and also that can be teed up by previous send outs, and on your website.

This can only help opening rates and audience engagement.
