WANT VS NEED
There's that lucky number again - 7!
This ad taps right into the core motivation of the reader (assuming they've targeted their audience) by using that little word need. This changes the reader's preconceptions from a 'want' into a 'need', which is a clever idea.
Note also the inclusion of the phrase written by email experts at Mailchimp. Including this phrase gives credibility and reassurance that it's going to be an authorative download by people with first hand expertise and knowledge of the subject.
A short, but highly effective ad that addresses the reader's primary concerns, whilst also getting the message across what the benefits are, ie selling out your next event.
