One Week Worth of Email Subject Line Tests

One thing I can tell you about our business is that we send a lot of email!

The cool thing about it is that it's free -- kind of. (As of this writing, we pay Mailchimp to help us with our delivery and list management). But the point is that email is an incredibly inexpensive marketing vehicle relative to some of your other options out there.

The awesome thing about email (for us nerdy marketers anyway) is that you can test lots and lots of different parts of the message including:

The email world is your oyster.

Anyway, we thought that we'd share the results from some of the emails we sent toward the beginning of September. The data below is specially for the various subject lines and how they performed from an open and click rate perspective.

Results of Email Subject Line Tests

As you can see, we didn't exactly have a lot of successful tests during that week. With the exception of email #1, the control subject outperformed the experiment. (I guess you could say that #4 was close to a tie!)

But it's this (sometimes frustrating) process of testing trial and error (split testing subject lines, varying copy length and style, and so much more) that, over time, can ultimately drive amazing email success for your brand.
