Why You Should Take Extra Care Sending Emails On A Monday

It’s awfully hard to get back to the daily grind after two days of doing whatever the heck you want. But every week it happens – Monday rears its ugly head. The first day of the working week has always been tough, and now we have the data to prove it.

We try to remember to proof read our emails before we hit send – we’re human, we all make mistakes. But apparently we make way more mistakes on a Monday than any other day.

American email management company Boomerang has analysed 250,000 emails to discover that on average emails sent on a Monday had the highest rate of errors in their subject line.

But who really cares. A typo is a typo, it’s not that important, right? Wrong. Emails that have spelling, punctuation or capitalisation errors in their subject line show a 14% change in the likelihood they will get a response. The most common mistake: not starting the subject line with a capital letter.

So every Monday as you type away, be sure you pay extra attention before you send your words off into internet land. As Wayne Campbell once said, “run them over with a fine tooth comb, dot the i’s and cross the… lowercase j’s.”

Unfortunately, it gets worse. The company also measured email subject lines in terms of sentiment, discovering that emails sent on Mondays show the least amount of positivity. So it’s true, there is such a thing as having a “case of the Mondays” – data says so.


And which day of the week had the most positive emails sent? Sunday, when we’re probably teeing up a bunch of fun lunch dates for the week ahead.
