Keep it simple
Marketing doesn't need to be complex.
As humans, we tend to complicate things where and when they do not need to be complicated.
This happens on both sides of the marketing coin too.
Internally, complicated processes lead to slower execution, more stress, difficulty training new teammates and more.
Externally, this looks like an alphabet soup of features, overuse of jargon and bullshit, cluttered visuals and unclear steps for customers.
Simplicity is the ultimate sophistication.
Leonardo da Vinci
Like Leo said, doing something that is perceived as 'simple' is actually quite hard.
If your internal content approval process takes 5 people and months of planning, it's too complicated. If you have 20 tools to send an email, ask yourself 'why?'.
I read a copywriting book once that said something like 'write down your copy, then cut it in half; then cut it in half again and then edit from there' - it's a good exercise to go through to boil down your points to the most digestible they can be.
And if your website, ads and other assets leave potential customers scratching their heads and asking 'what do they do?' then it's time to pump the brakes and get back to basics.
No one is going to be mad at you for making your messaging crystal clear.
In the end, simple processes and simple creative make for happier teams and better marketing. Win-win.
