In preparation for my upcoming Science of Email Marketing webinar , I've been digging into a giant dataset of over 9.5 billion email sends from our friends at Mailchimp , and I've found a number of surprising things.
The first thing I noticed was that emails sent on Saturdays and Sundays tend to have much higher clickthrough rates than those sent during the business week.
I also found that unsubscription rates tend to peak on Tuesday and are the lowest on Thursdays. From an unsubscription perspective, Saturdays are one of the best days.
The takeaway here is that you should start to think about experimenting with sending your email campaigns on Saturdays. And don't forget to register for the Science of Email Marketing Webinar .
