We suspect that there has been no necessary evil like email. 2.4 million are sent every second, translating to 74 trillion a year. That’s a lot of crap no one will ever read.
But what’s stopping someone from reading email you send? According to Boomerang, an email tool that lets you schedule messages, the worst thing you can do is put a spelling or grammatical error in your subject line. They analysed 150,000 emails, and they found that having a spelling or grammatical error in the subject line can decrease the chance an email is opened from 34% to 29%. The worst offender? Capitalisation errors. Inappropriate capitalisation decreases the chance an email gets opened by a solid 15%.
Additional fun fact: Monday had more errors than any other day of the week.
