How To

Improve Your Email Programs: 5 Test Ideas

SUMMARY: Need inspiration for your next email test? Here are five examples of successful tests shared by presenters at our recent Email Marketing Summit.

Read on for five ideas you can incorporate into your 2010 testing plans. Includes tests to help improve:
o Opt-in tactics
o Personalization
o Design and layout
o Video links
o Frequency
Itís still early enough in the year to plan a series of tests that can improve the effectiveness of your email marketing programs. To get you started, weíve compiled five test ideas to consider, which were shared by a presenter at our recent Email Marketing Summit in Miami.

Some tests focus on simple changes, such as personalizing "from" lines and subject lines. Others require a little more work, such as email template changes and frequency tests. But each test described below delivered meaningful improvements in a marketerís key metrics, such as opt-in rates, open rates, clickthroughs and revenue.

Here are five tests to consider:

Test idea #1. Opt-in incentives

Although your email newsletters, alerts and other programs should provide enough value to attract subscribers, you also can offer an immediate reward for new opt-in registrations.

Consider providing a tangible incentive for new opt-ins, such as a coupon or free gift. Adrian Olvera, Sr. Marketing Consultant, Dell, and his team tested the impact of a coupon incentive for new opt-ins during the holiday shopping season.

They offered 20% off select products for new opt-ins. Result:
o 14x lift in average opt-in rate during the holiday season

Test idea #2. Personalization

Multiple speakers at the Summit reminded attendees about the value of personalizing email communications. The closer marketers can get to creating a sense of one-to-one communication with their email messages, the better the response is likely to be.

To know for sure, test personalizing your messages for both the sender and the recipient.

John Mast, VP Marketing, Expedia CruiseShipCenters, shared the results of his teamís personalization tests:

- First, they began sending emails from a real consultant in their travel agent network -- i.e., from "Cathy Cruiser" rather than the from the generic Expedia CruiseShipCenters email address.

Results:
o 5.5% higher open rate
o 23% higher clickthrough rate
o Less likely to be unsubscribed, or flagged by subscribers as spam

- Next, they personalized the subject line with the recipientís first name -- "Dave, Your 7 Day Alaskan Cruise Awaits."

Result:
o 10% lift in open rates

Test idea #3. Call-to-action placement and button size

Email design and layout tests are another prime area to find improvements. Moves as simple as increasing the size, shape or color of buttons, and the placement of those calls-to-action, can often deliver a meaningful boost in key metrics.

Shinn Chen, Marketing Manager, Salesforce.com, shared the results of his teamís template redesign. As part of a broader redesign, they made two changes to highlight the calls-to-action:

- Call-to-action was moved from a small box on right side of messages to just below the messageís headline and subhed, in line with the rest of the body copy.

- Clickable buttons were made much larger (see Creative Samples below).

- Results:
o CTR increased 26%-27%

Test idea #4. Video links

Video content is an important element to test in your email campaigns. Watching online video is one of the most popular activities on the Internet: In 2008, there were more videos watched online than there were searches on Google, according to MarketingSherpaís "Marketing with Video Report."

Technical issues and deliverability hurdles make embedding video directly into email a significant challenge for marketers, but you can still promote video content in your messages by:
o Displaying a screenshot of the video
o Embedding a link for video playback

Rick Chin, Solutions Marketing Manager, Interactive Intelligence, described how his team has been including video screenshots and playback links in their email newsletters. The new content has proved exceptionally popular with subscribers:
o Video links receive double or triple the number of clicks as text links

Test idea #5. Email frequency

Many marketers establish their email frequency based on assumptions and industry best practices, such as monthly newsletters or weekly product offers. But best practices are a starting point for further tests -- not necessarily the best approach for your programs.

Testing can determine the optimal frequency for a specific email program: The point at which you maximize revenue from those messages without increasing the rate of unsubscribes.

Dr. Flint McGlaughlin, Director, MarketingExperiments, described a test his team performed with an ecommerce partner selling special-occasion gifts:

- They identified a highly motivated and loyal segment of the partnerís email list for the test.

- Over the course of 60 days, they tested various message frequencies to that segment, ranging from one message every other day to one message every three weeks.

- They monitored monthly revenue from email along with unsubscribe rates.

- Results:
o Sending an email once every other day increased revenue 3x compared to sending email once a week
o Unsubscribe rates on a per-message basis did not rise significantly
