What’s the best symbol to use to separate multiple propositions within a single subject line?

Here at Alchemy Worx, we feel very strongly – supported by the evidence – about the commercial benefits of emails with long subject lines. We’ve found that emails with longer subject lines containing promoting multiple elements achieve better click to open rates, probably because recipients get to scan and choose from a range of items rather than simply accept or reject a single thought.

Those elements need to be separated, of course, which has led us to wonder about the best way to separate multiple propositions within a single subject line. And so we enter the surprisingly complex world of punctuation and ask: what symbol or word helps people to scan best between different items in a subject line? Which of these subject lines do you think generated the most clicks? Vote now to see which test won, as well as the results from our other subject line tests.
