How To Test Your Email Subject Lines

Have you ever sent out an email blast that was opened by only a fraction of the people on your list? Argghh. It’s happened to me and I know how it feels. It’s a bummer when you worked hard to create stellar content that only a people read. Are you talking to air? Well, yeah, you are. But I have a solution for you. This is when a simple A/B email subject line test can be super helpful. It’s very easy to do (if I can do it, so can you)!

How To Test Your Email Subject Lines 

Chances are you use one of the popular email services to manage your list. Whether yours is Mailchimp, Constant Contact, Infusionsoft, or another, they all offer a simple way to set-up an email subject line test. I usually test only two (an A/B test) but you can test more if you like.  

Here’s how to create an A/B subject line test:

1. First write your email content. Always write your email content first. OK, enough of that. I think you get it.

2. Next, create two subject lines, both of which you feel are compelling, but are different. For example, A could be in a question form and B could be a statement.

3. Using your email service’s testing tool, set up your test to have a small percentage of your list receive your email with subject line A and another small percentage will receive subject line B. If you use Mailchimp you may get a pop-up telling you that A/B testing works best with a larger list than what you have. Just ignore that and do it anyway (sorry, Mailchimp!). 

4. Choose the amount of time you want to wait before the winner is identified. For Tuesday Tips, I usually only wait about 2-3 hours, since it has to be sent on a Tuesday. However, if your email is not time-sensitive you may want to wait 24 hours or more for even better results. I often notice people will open my emails many days after they are first sent.

5. Your email service will automatically tabulate the winner by which one got more opens. It will then send the email with the winning subject line to the balance of your list. I think this is really magical! (the geek in me).

6. If your email is not time sensitive, here’s a great trick. Wait a few days, then send your email with the winning subject line to the people who were in the test group and received the losing subject line, and who did not open it.

Campaign #2:
A. Blogging is Not a Pain in the Arse
B. Afraid of blogging? Think About This:

Did you guess right? Enter your guesses in the comments section and I’ll disclose the winning subject lines next Tuesday with some thoughts about why.
