Meet the number cruncher for subject line awesomeness
Hi, I’m Trevor, and I’m an Analytical Linguist at Phrasee.
You may be wondering why we need your average open rate…
Well. A crucial value for this calculation is the average number of opens you get per campaign. Two different organizations might each have an audience of 1 million. But if one has an average open rate of 10% and the other 20%, they’ll have different splits. TL;DR; open rates matter to the math.
