37. Types of Testing
A|B Testing
• Testing one element against a control
Multi-Variant
• Testing multiple elements against a control
Local Control Groups
• Isolation of a population on a campaign level to see % of lift
Universal Control Groups
• Isolation of a permanent population to see percentage of lift over time
38. A|B Testing
Definition
• 2 email creative that are
identical but with one
element changed in one
version
Pros
• Simple testing that is built
into most email platforms
• Systems usually handle
division of population
• Results are easy to
understand and act upon
Cons
• Populations must be equal
• Time periods must be
significant to judge results
• Limited to one variable so
extended testing can be long
39. Multivariate Testing
Definition
Using one region in multiple
email creative with changes in
each sent to equal populations to
determine a better performing
email
Pros
• Multiple elements can be
tested at the same time
Cons
• Populations in each group
must be equal
• Most email populations do
not have enough equal parts
to be statistically relevant
40. Local Control Groups
Definition
Isolation of a small but significant
population from an email
campaign to see what happens
with their behavior against those
that received an email
Pros
• Can show the influence that
and individual email has on a
campaign level
• Population must be reflective
of the entire list
Cons
• Sometimes hard to manage
from a population
• Some people that are
active/buyers will not get a
message
• Must involve pre-planning
41. Universal Control Group
Definition
Isolating a population over a
longer period of time to see
what their behavior is against
those that receive email
Pros
• Gives email a true ROI
number
Cons
• Isolation of a population
means that some customers
don’t get an email
• Hard sell internally
• Must educate various groups
internally

CONFIDENCE INTERVALS
43. Sample Size Determination
There is no perfect answer in determining sample size. It is a trade-off between
sample size and the difference between A and B it is important for us to detect.
Acxiom presents a chart (as seen below) to help clients find their optimal balance.
The smaller the
difference we want to
be able to detect, the
greater the required
sample size
43
44. Example Confidence Interval
• We have some results from an A/B Test:
o How much confidence do we have in these estimates?
o Do we feel comfortable enough in the observed gain of .3% to switch
to B?
– It’s all about Sample Size when considering confidence in
Response Rates.
44
45. Example Confidence Interval
•
•
We observed B as 0.3% greater than A.
•
We can now use our confidence interval for the difference (B – A) to establish how
tight that 0.3% difference is based on our sample sizes
•
45
The 95% Confidence Interval indicates we are 95% certain the RANGE of the
interval captures the True response rate
The range includes A being .8% greater than B all the way to B being 1.4% greater
than A. With this wide range of possibilities, taking action based on our estimates
becomes very dangerous
46. Example Confidence Interval
• Let’s say we have the same results, but instead of results based on
samples of 1,000 each, they are now based samples of 50,000 each.
• We now have more evidence, due to our greater sample size. This
results in greater belief in our results (estimates), and hence tighter
intervals
• We still observe B as 0.3% greater than A, however now we can
now conclude B is greater than A by between 0.1% and 0.5%.

5. Get extra pairs of eyes – make it a team effort
52. One point to remember about the plan
• Does the result really
prove the point?
– Always work to validate
your testing
– Sometimes thing “win”
because they’re
different
• Recognize the “shiny
objects”

64. Example Confidence Interval
How did we get the confidence intervals?
Confidence Interval for one proportion:
Test A = 0.015 +/Test B = 0.018 +/-
1.96*SqRt ( (0.015 x 0.985) / 1,000 ) = 0.015 +/- 0.008 = (0.7%, 2.3%)
1.96*SqRt ( (0.018 x 0.982) / 1,000 ) = 0.018 +/- 0.008 = (1.0%, 2.6%)
Confidence Interval for difference between two proportions:
Test (B – A) = 0.003 +/- 1.96*SqRt ( ((0.015 x 0.985) / 1,000 ) + ((0.018 x 0.982) / 1,000) )
Test (B – A) = 0.003 +/- 0.011 =
Test (B – A) = (-0.8%, 1.4%)

Hinweis der Redaktion
ADDRESS VALIDATION AND ACQUISITION ASKConsumers have up to 3 email addresses. The first being their primary email address. The second being a “junk” account for emails they never intend to open and the third is generally an old email address that they have moved to another account but check rarely to see if anyone emailed them.It’s because of this that the marketer really has to work at making sure that during email acquisition, they provide a very compelling and real reason as to why the consumer should supply their address. If you ask for nothing, you generally will get nothing.LESSON FOR CLIENTS: Ensure that their acquisition page gives benefits (not reasons) to sign up and shows clear value. Show samples of creative, ideas of how many times they will get email a week and make sure it reflects brand positioning.
CTA/DESIGN:How many times do we get an offer in an email that we “intend” to take advantage of? “Oh, that’s a great email, I will read it later when I have time” and that time never comes. We are an instant gratification society and as such, we need to create a sense of urgency about the emails that we send. Don’t send a memo or a webpage…send an email with a strong and compelling call to action.Lesson for Clients: Test different CTA’s like Learn More instead of Buy Now. You may find that if you change this call to action, you have an increase in CTR and other associated KPI’s. Also, make sure that your message is clear. Can you tell in 3 seconds what you should be doing? If not, look to simplify your message from the end-users perspective….not yours. You are not your own customer. Remember that.
WHY CONSUMERS LOVE EMAIL: Many believe that discounts are the only value to email marketing. That every email has to have a discount or incentive. Based on our study and other studies using Big Data, that’s wrong. Some consumers don’t care about price. When we need something, sometimes, we just get it. Also, consumers are researching more before big purchases. How are we serving that need? Aren’t we diminishing the value of our brand by tying it to a promotional offer? Work with allocating some of the space in email to value statements. Customer reviews, tips & tricks and advice from your leadership in a vertical can resonate with the consumer. Help your consumer fall in love with your brand. If you just focus on the discount, you’re only as good as your last offer.LESSON: Don’t just rely on offers to generate business. Try content, tips & tricks and customer reviews.
SEND TIME OPTIMIZATION: How many of us wake up and reach for our cell phone or tablet? LOTS OF US! We’re a sick people that we’re obsessed with our devices. I know when I wake up I am easily annoyed, so doesn’t it make sense to think about what messages I should see? We know that consumers triage their email (delete emails that appear to be irrelevant en masse). According to a recent BlueHornet.com study, 20% of consumers always triage while 55% say they sometimes triage. So, let’s think about when we send these emails of ours. For example, for a credit card company. Does it make sense to send a credit card offer for morning arrival? Am I going to apply for said card when I wake up? Possibly not. BUT, I may be really excited on a Saturday morning about the sale at Macy’s. LESSON FOR CLIENTS: Think about your message and test the optimal time of the day to send your message. Try testing in the evening or even Friday evening for retail based business.
SEND TIME OPTIMIZATION: Just like the 36% of consumers who check their email before they get out of bed, there’s another group that checks email before breakfast. The same rules and trains of thoughts apply to early morning messages. Think about what you want the consumer to do and if it really fits within a morning context.LESSON: Test when you send and be wary of complex CTA in the morning.

DEVICE USAGE: Consumers are getting more portable. With this portability of information, we are seeing a fundamental shift in how consumers access information that is central to their lives. Email, websites, apps and information is now at our fingertips. We have to be conscious of the fact that when email’s are read on a smartphone, it’s tiny. In the morning, we want to make sure that we don’t annoy our customers or make it too hard to read. Responsive design is a must have in the emails that we send. Make sure that your message does not get lost cause “it’s too tiny”.LESSON: Implement a standard responsive design template. That will help in product timelines and readability by the consumer.
EMAIL IS DOMINANT: Along with the expanded use of mobile devices, we see that email continues to be a core functionality that consumers use on a daily basis. While these statistics do change based on demographic, we can reasonably assure marketers that email is still alive and imperative to any communications channel.LESSON: Track statistics for your consumers that are consuming email on a mobile device.
EMAIL CONSUMPTION: As previously stated, email is a core function of mobile devices. With 91% of consumers checking email on their mobile phones, why would any company want it to look bad? “If you have to pinch it, you’re doing it wrong” is a phrase that adequately captures the belief that email should represent brand. We should not ask our consumers to do work for us just because we as marketers are too lazy to do a responsive design. Would you design an email that looks bad? Well, every time you don’t put an email in a responsive format, your designing and sending a bad email.LESSON: Capture and track the mobile opens of your subscribers and implement a standard mobile friendly design.
PASSBOOK: iPhone users have a bunch of options with not only functionality but with apps. According to ZDNet “In the US app store, there are currently only around two dozen apps optimized for Passbook, including Starbucks, LivingSocial, Amtrak, Walgreens, Office Depot and Sephora To Go.” There is a large opportunity here for delivering content. It could be coupons, passes, tickets or more. Links from email to passbook functionality can be key to stickiness. Payment options are also an option, like in the Starbucks card.LESSON: Try to link coupons to passbook and look at adoption and redemption. For annual sales or specials, test out the functionality.
GET EXCITED: One of the shifts we continue to see is that consumers consume information at different times. Think about the last time you were in the elevator. Instead of looking at the floor indicator, many will grab their phones. Idle time is phone time….and email time. Use this effectively by having a strong and actionable CTA and test different times for sending. Don’t get hung up on “Mary reads her emails at this time everyday” but rather optimize your message to be taken advantage of anytime AND test into the optimal time that works. Don’t just follow the crowd and send at 6AM. Establish your own benchmark.LESSON: Develop strong and actionable CTA’s in your email.
