From the graph labels, it appears the subject line which moved the most relevant info to the front won, as opposed to leaving out the startup name or pushing it to the end.

But, they don't mention the sample size, and they do mention that there were other changes in the email content and call-to-action. Nor do they make any mention of statistical significance.

So we can't tell what actually helped, only that perhaps (if we assume did their significance-testing correctly) that some set of changes can make a big difference.

Pasting in the emails was going to make the post very long, but to summarize, we presented Meritful as a tool for students to build a positive web presence, as a tool for teachers and mentors to run projects and give feedback to students, as a tool to help with college admissions by creating an impressive portfolio and interaction from respected folk and another comparing Meritful to existing products for teens.

The sample size was roughly evenly split between the total number of contacts we had.
