Phrasee Subject Line Checker
30 Aug 2019
It’s never been a more challenging time for retailers to stand out in a crowded modern inbox and not many people realize the opportunity cost of using ineffective copy in their subject lines.
Many factors contribute to copywriting success. One important factor is “linguistic diversity”. By that, we mean the use of different combinations of language properties. Using the same language repetitively decreases copywriting performance over time, meaning less engagement and less revenue for your brand.
We've built a tool that calculates your subject line language diversity score to see how your copywriting stacks up in a crowded modern inbox.
