For the relaunch of the emailmonday newsletter, I thought it was fun to do a email subjectline test and ask Marketers, which one they tought would win.

This was done in a unique position: * The list wasn’t mailed in a long time so a complete chance to re-engage with my email list * A new formula was introduced with now curated content, engagement prompts & exclusive content! We tested the following subject lines: A: I promised to get back to you with these Golden Nuggets B: Your marketing briefing had to reboot – Results inside or was there no winner between the two?117 people voted for which they thought would be winning….

And people commented as well – thanks gang!

So what are we really testing with these two? (Hypothesis)

Both of the options present a change but A is pointing towards the relation (I promised) and B to something of theirs (Their Briefing). Both creating some tension – and excitement (maybe?). The Hypothesis (what I thought would happen, and wanted to test) was: “More subscribers will open the newsletter when re-engaging after a long time when pointing to the relation.” Now the Hypothesis is good, but I know based on the test you can’t 100% say that was the ONLY difference between the two. What do you think? But this is the lesson: Even if you are doing a “random” test, think of a reason why. – why would one do better than the other? That is rationale and will inspire further tests!

Other subject lines considered (because you should alway write more than just two subkject lines) 1: Oops, this is the only Marketing Vacation you don’t want. 2: Arnolds “I’ll be back” method put into Marketing Action 3: This Hibernating Superpower made the Avengers look like Pussies. 4: Why All-You-Can-Eat isn’t great for marketing. 5: 10,9,8,7.. Re-booting the email formula We’ll be doing more unique, exclusive things like this and experiments, so give in to your FOMO and subscribe to that newsleter.
