Imagine a fitness guru who designed a workout program for you that requires just one repetition per exercise. One pushup. One crunch. One stretch.
Crazy, right? No one would tone up with that.
It’s the same with marketing communications. You need a lot of reps (frequency is the common term) if you want to build up your marketing muscle. Think multiple emails, multiple ads, multiple newsletters.
It’s not glamorous, but it’s what works.
