When it comes to email writing, every marketer seems to be a “guru” or an “expert”, incessantly offering tips and tricks on the latest trends.

But the trouble is, while advice based on someone’s personal experience is one way to come to conclusions on email performance – the sources behind that advice are often flimsy.

Basing your email writing on hard data – preferably that from a large sample size – is a much more watertight solution to crafting successful subject lines and boosting your open rates.
