Testing for Email Marketing Success

It is always surprising to learn when companies have not incorporated basic tests into their previous email marketing efforts. 

Of course, there are many reasons for this -- with responses ranging from "you can do that?!" to technology limitations, to lack of time, or even lack of perceived value.  Alas, many companies still send out one email to their entire file.

Why should you test?

There are many reasons to test in emails.  Among them, testing forces you to:

• Put assumptions and biases aside;
• Learn what motivates customer behavior;
• While at the same time (presumably) creating more personalized and targeted emails....

The net effect of testing should be increased sales and customer loyalty, as well as you becoming a better email marketer.

Here are some basic email tests you can try.

Test 1: Does Personalization Boost Response?

Segment 1 Example: [First Name], Get the Latest New Products!
Segment 2 Example: Get the Latest New Products!

To verify your results, it is best practice to reverse the test on the next email before making a conclusion -- so in the next email, Segment 1 WILL NOT receive their first name in the subject line, but Segment 2 will.  It might look like this:

Segment 1 Example Subject Line: Free Gift Offer Inside
Segment 2 Example Subject Line: [First Name], Free Gift Offer Inside

Personalization can take many forms aside from being used in the subject line, as shown in this example. It could include content

Test 2: Which Offers Perform Best?

Segment 1 Example Subject Line: [First Name], Get 15% Off Your Next Order
Segment 2 Example Subject Line: [First Name], Save $10 Off Your Next Order

Of course, you'll have to include unique offer codes within each email to measure the sales results separately, but really the only variable changing is the offer itself.

On the next email, switch the offers but change the subject line slightly, as well as create fresh content -- you don't want to be boring or predictable!

Segment 1 Example Subject Line: [First Name], Limited Time Only to Save $10
Segment 2 Example Subject Line: [First Name], Limited Time Only to Get 15% Off

You might also consider testing Free Gift vs No Free Gift, Free Shipping vs Dollar (or Percent) Off, Minimum Order Values required to receive an offer, etc.

Test 3: How Does Performance Vary by Order Recency?
For this email you'll have to run a sales report to obtain the last-date-of-sale for each email address, then sort your email addresses from "Most Recent Order Date" to "Least Recent Order Date."

Then, create two equal sized groups -- one for your oldest orderers, one for your newest orderers -- and send them an identical email.

Segment 1 Example Subject Line: Top 5 Holiday Gift Ideas
Segment 2 Example Subject Line: Top 5 Holiday Gift Ideas

You'll likely want to repeat this test on your next email to validate results.

Test 4: How Does Performance Vary by Lifetime Orders?
For this email you'll have to run a sales report to "count" the number of orders placed by each customer. Sort your results from "most lifetime orders" to "least lifetime orders."

Then, create two groups -- one for customers that have placed just 1 order, one for customers that placed 2 or more orders -- and send them an identical email.

Segment 1 Example Subject Line: 10 Most Highly Reviewed Birthday Gifts
Segment 2 Example Subject Line: 10 Most Highly Reviewed Birthday Gifts

Then, repeat this test on your next email to validate results.

Goals
The goals of testing should certainly include:

• Learn what motivates customer behavior
• Determine performance differences based on customer order history
• Send more interesting and targeted emails
• Increase sales and customer loyalty

Apply what you learn from email to other marketing activities that may be more expensive or have longer lasting effects. 

Change the role of email into an important research tool that can benefit other areas of your company!
