Emails sent on Sundays garner the highest open rates.

It goes against most of the marketing advice I’ve received, but Clickz reports on a MailerMailer study that shows that Sunday emails have the highest open rate, followed by Monday morning.

Other findings of the report, as listed by Clickz are:

  • E-mails are getting opened faster. Nearly one-third of opens occur within the first two hours — a 10 percent increase. This is likely because more people are using mobile e-mail readers, like the iPhone.
  • Short subject lines are still working better than longer ones in most tests. MailerMailer reports that open rates decrease as subject line length increases. Subject lines with less than 35 characters seem to have a marked advantage.
  • Subject lines with “hot button” messages work best of all.

    It stands to reason why sundays is a good day for sending emails. Most people are off work and probably spend a lot of there time on the computer.

  2. Thanks for this post.

    I’m really surprised that Sunday is a good day. I guess many people are more relaxed and have more spare time so they probably read more emails.

  3. This is really interesting, I’ll make sure I send most of my mail on a Sunday from now on!
