Hi, I’m Molly, and I lead Phrasee’s global team of language technicians.
We build our customers’ language models and translate performance into actionable insights.
Everyone always asks, “What makes a good subject line?” We find this question fascinating! We’ve researched millions of them and found that no one feature (like sprinkling in emojis) causes uplift, but increasing making your subject lines more diverse does!
This is why we encourage as much variance within tests as possible. From emoji placement to length and syntax, diversity is always key.
