A/B Testing for Fun and Profit [Subject Line Writing Contest]


If you’ve read the MarketingExperiments Blog for any length of time, you know that A/B testing and conversion optimization can be a very profitable endeavor. You can receive 90% more trial sign-ups, a 1,312% increase in the start rate of a multistep process, 331% more leads from a homepage, and the list can go on and on.


Split testing can be fun, too

Aside from improving results, the sociologist in me finds it fun to create a few possible headlines or subject lines, release them into the world, and see how customers react.

I’m not alone. For example, when Amelia Showalter, Director of Digital Analytics, Obama for America, discussed the A/B testing that helped generate $500 million in online donations for the president’s re-election campaign, she mentioned the fun the analytics and email teams had as well.


“There was this thing called the Email Derby … ”

“It was really fun,” Amelia said. “We started an informal poll.”

They asked the teams which subject lines being tested would win, and which would lose.

At MarketingExperiments, we’ve been known to have a little fun with surprising test results as well, thanks to a very gracious CEO.


Let’s have some fun, and give you a chance to win a ticket to Email Summit (plus hotel)

Online marketing can be a tough daily slog in the trenches, so to help you have a little fun with A/B testing, we’ve thrown down a challenge to the readers at Copyblogger.

We’ve said you, the dear readers of the MarketingExperiments Blog, are not only smarter, more fun to be around, and more physically attractive than the readers of Copyblogger – you are more effective subject line writers, thanks to all you’ve learned from A/B testing.

If you scroll down, you’ll see the exact copy of an email we are going to send promoting MarketingSherpa Email Summit 2014 in Las Vegas. We’re asking you to write the best subject line you can think of, and leave it as a comment for this blog post.

Then, the MECLABS optimization team will read each and every comment and hand-pick the five subject lines they hypothesize will perform best. Copyblogger’s team will also pick five subject lines from its blog as well.

We’ll then run all 10 of those subject lines in a split test.

The writer of the subject line that generates the most unique clickthroughs will receive a complimentary ticket to Email Summit 2014. We’ll even put you up in the host hotel, the Aria Resort & Casino, for two nights.

The writer of the subject line that receives the highest open rate (CTR is our primary KPI, or key performance indicator, but opens will be a secondary KPI), will receive complimentary access to the MECLABS Email Messaging Online Course.

If you’re the type of marketer that likes diving into the details, you can read the official rules.


Now, let’s see your high-performing subject line

Sound like fun? Great, let’s see what you’ve got. Below is the email we will be sending. Write your best subject line, and leave it as a comment to this blog post. Easy peasy.
