Improve your email and drip marketing copy with a simple tool.
Use this one weird trick to see if your marketing copy is effective!
The Gunning-Fog index is a simple formula that you can use to judge the complexity of your writing. It uses a weighted average of the length of your sentences and the number of complex words you use to compute a single number indicating the difficulty of your prose. The number is weighted so that it corresponds, approximately, with the education grade necessary for a reader to understand your copy fully on the first pass.
It's not perfect, but it's a nice, quick way to help you proofread and edit your copy for readibility.
We've made a free utility for you to calculate the Gunning-Fog index of your writing. Head over to https://addressbin.com/tools/gfi/ to try it out!
