Recipients DO judge an email based on its cover, in this case, is the email subject line

33% of recipients decide whether to open an email or not based on the subject line they read. 

Eh.. only 33%? That's pretty small fraction.. why should I care?

Imagine when you send out 1000 emails to 1000 different recipients. And 330 of them go straight to the trash. That's not a small fraction at all!

Don't overcomplicate your message, not everyone understands complex words or sentences. Keep it simple.
