Which Subject Line Won?

Email is a funny thing.

You can spend hours writing a well-thought out sales email… only to see it flop. And you can kick out something in minutes that creates a buying frenzy.

Naturally, your subject line plays a huge role in whether your email even gets opened. And, in theory, this also affects your sales.

With that in mind, let’s play a little game. You read the two subject lines below, and then see if you can pick which subject line won. Got it? Okay…

  • Subject Line #1: Long-Shot Leads to Unexpected Win
  • Subject Line #2: China tells U.S. to “go straight to hell.”

Just to give you a little bit more background on these emails, both were sent to a house list of folks interested in trading. Both sold the same product at the same price. And both “piggy-backed” on news events.

The first email piggy-backed on the 2009 Superbowl. The second email piggy-backed on China’s move to unload the fraudulent derivative products sold to them by U.S. banks.

So both had tie-ins to events that would have been top of mind for most traders.

Alright, have you made your decision?

Good, let’s move forward.

Here are the open rates for each email:

  • Subject Line #1: 741 opens
  • Subject Line #2: 1,434 opens

Did you guess right?

Well, maybe you did and maybe you didn’t — but you actually don’t know yet.

That’s because open rates are a relatively meaningless metric. Think of print advertisements. You don’t care how many people read your headline; you care about how many people actually buy.

Fortunately, this particular client took my recommendation to buy some simple (and affordable) ad tracking software.

We use this software program to track the open rates and sales of every email we send out. (We also track ads by source so we know when our advertising dollars are working and when they’re not.)

Because we track emails like this, I can tell you that the real winner was Subject Line #1 — and NOT Subject Line #2 as you probably guessed.

Here are the numbers:

  • Subject Line #1: Long-Shot Leads to Unexpected Win – 741 opens, 17 sales
  • Subject Line #2: China tells U.S. to “go straight to hell.” – 1,434 opens, 9 sales

If you’re paying close attention, the first email got about half as many opens… but… almost double the sales!

This real-life example proves that while your subject line matters — and you should always aim to get your emails opened — a high open rate does not necessarily guarantee a greater number of sales.

And while this example may be appear to be an anomaly, I promise you: it isn’t. I’ve seen this same story played out a number of times.

I have a theory about this.

There are people on every email list who will never buy. They’re either freebie seekers or they’re just not interested in what you have to offer. This is a fact.

Unfortunately, we tend to think that everybody on a list is a potential buyer… and so we try to write for the list.

This is a mistake because “the list” doesn’t buy. Individual people on the list do.

So when you write emails, try to imagine your ideal buyer. Write to that guy. And don’t worry about all the non-buyers — they’re never going to buy anything anyway.

Said another way, don’t focus on maximizing attention; focus on maximizing sales. Don’t write to the list; write to the latent buyers on the list.

Making this simple mindset shift could make a massive difference in the results you get from your email marketing.

P.S. How do you know which emails are really working and which ones aren’t? And how do you know which ads are worth running again? Well, you can’t really know — unless you track your ads by source.

  • Although, this would be true in most cases, when we are selling impromptu buys, the open rate becomes very important.
  • Very true... because at that point an "open" would become more synonymous with a sale.

    I never learned any of this stuff until recently. I intuited it from years of experience of response or non response to my emails. I'm so glad to have it put so simply! THANK YOU!!
  • You are very welcome, Anne. I hope to write more about email subject lines in the future.
  • If headline one was more -relevant- to the offer on the page, it wins.
  • Good point... in this case neither subject line was especially relevant to the offer. That said, the "Long Shot" subject line appeals to the gambling mentality most traders have.
  • Ryan, this post is a classic. "“the list” doesn’t buy. Individual people on the list do."

    Tracking is such a major component of copywriting campaigns.

    Thanks for putting it so clearly and eloquently.
  • Marya - Thank you! Glad you liked it. :-)

    Good post Ryan.

    I assume what you're telling us is that the second headline really wasn't a good qualifier.

    Before I looked at the answer, I thought that the second headline would be the one that got the better open rate (It's the one that appealed to me), but the first might appeal to risk takers, which many traders are, I would think.

    It would be instructive to see the e-mail (or subsequent sales letter) that prompted the eventual sales. Did it appeal to the gamblers? If risk taking wasn't the driving impetus, did you identify what was? And finally, could the 741 members be segmented and tested as a niche for marketing the kind of product they did buy?

    Best wishes,

  • Hey Barry,

    Thanks for reading and commenting.

    The "China" email was more about being prepared if/when the market drops -- but didn't do much product-specific selling in the email itself. It was a fear-based email encouraging traders to be ready to scalp profits in the near future. (Prevention/preparation is always a harder sell.)

    The "Long Shot" email compared football to trading and made the point that you could pull off big wins even when it looked like the market was moving against you.

    There was more product-specific selling in this email -- with screen shots -- and a final call to action that tied in the football theme:

    "Try it risk-free and experience your own game-winning scoring drive today..."

    Then a link to buy.

    So after examining the two more closely, it's fairly clear why the "Long Shot" email got more sales.
