Delivered and opened

Simple but effective tactics help retailers get their e-mails read by consumers.

To get more utility out of its e-mail list, vitamins and supplements e-retailer Natural Partners Inc. was looking for ways to increase its e-mail marketing campaigns' open rates. Last November, it decided to try limited-time daily deals, making them available only to shoppers who subscribed to an e-mail list specifically for these offers.

The merchant encouraged consumers to subscribe to the e-mails in the weekly e-mail it sent to consumers on its general e-mail list. It also generated a list of customers who opened Natural Partners' weekly e-mails most often and sent them a message saying it was their last chance to register for the limited-time daily deals.

Then Natural Partners began sending the daily-deal e-mails to the special list it created. Open rates for the e-mails were high—one of the e-mails registered an open rate of 76%, the e-retailer says. It credits the appeal of daily deals and the ability to segment a list based on consumers' open rates for the success. Natural Partners used services from digital and mobile marketing firm Knotice Ltd. to segment the list.

"We found out the accounts that most often opened e-mails were generally our online purchasers, and they preferred to be contacted through e-mail," Brittany Johnson, marketing manager at Natural Partners, says. "The daily-deal e-mail blasts worked well for us because not only did we have the right audience, but we also only ran the daily deals for a very short amount of time."

The deals themselves were successful beyond just the high open rates, Johnson says. Consider the results for one of the daily-deal e-mails: Natural Partners sent 649 e-mails and subscribers opened 308 for an open rate of 47.46%. The e-retailer typically sells seven units per day of the product highlighted in the e-mail but sold 128 at the deal price, a 1,729% increase in sales. These open and response rates are typical for Natural Partners' daily-deal e-mail offers, Johnson says. She declines to reveal what Natural Partners pays Knotice for the e-mail marketing and customer profiling systems.

Key performance indicators

To be successful in e-mail marketing, marketers must ensure their e-mails are delivered to customers' inboxes without incident and convince customers to open the messages. The U.S. retail industry average marketing e-mail delivery rate is 96%, according to a 2012 study by e-mail marketing services provider Return Path Inc. The average open rate for North American retail industry marketing e-mails is 20.5%, according to a 2012 study by e-mail marketing services provider Experian CheetahMail.

The yardstick for e-mail deliverability used to be measured by whether recipients flagged messages as spam. Too many spam flags and the providers of e-mail services to consumers, such as Yahoo, Google, Microsoft, Comcast and others (typically referred to anachronistically as Internet service providers, or ISPs, even though they don't necessarily provide a consumer's Internet service) would block a sender's messages. But the simplicity of that cause and effect led marketers to game the system, bloating their subscriber rolls with subscribers who didn't complain but were not engaged.

ISPs today measure how customers engage with the e-mail messages they deliver, such as the open rate, and that plays a role in deciding whether they'll deliver future messages from the same sender, experts say. To entice consumers to open their messages, marketers are using varied strategies, including daily deals, segmenting, timing, personalization and special symbols in subject lines.

Managing the inactive

"It's a new world for deliverability," Chad White, principal of marketing research at e-mail services provider ExactTarget, says. "You have to manage inactive subscribers."

At chain apparel retailer J. Jill, e-mail marketing manager Kate DeLanders has launched an automated program that seeks permission from inactive subscribers (she declines to reveal what percentage of her list is inactive) to send them e-mails, even though it already has permission from when the subscribers first signed up.

J. Jill, which uses e-mail marketing services and technology from Responsys Inc., turned to this tactic to weed out inactive consumers and make its list more active and engaged, which is what the e-mail inbox providers are looking for.

"They are not active at this point. It will hurt us a lot more if we keep sending them e-mails," DeLanders says. "The Internet service providers want to make sure our IP address is sending to people who are actually opening and clicking and engaging with our e-mails. So this is a proactive approach. It's like flossing: No one wants to do it but you must to stay healthy."

Good timing

Once a merchant successfully delivers an e-mail, the next step is to get the consumer to open that message. For J. Jill, timing turned out to be key to better open rates.

With the system it was using prior to Responsys, J. Jill sent out e-mails in batches every few days. The merchant was running remarketing campaigns, e-mailing customers who abandoned carts or browsed products on the site but left without taking any action. But because the previous system, which DeLanders declines to name, was oriented toward batching e-mails every few days, a cart abandonment e-mail could hit a consumer's inbox a few hours after that consumer left or a few days later.

Responsys switched J. Jill over to daily e-mails and the merchant saw immediate success.

"Relevancy was really crucial with these messages," DeLanders says. The new schedule produced a 3.6% lift in cart abandonment e-mail open rates and a 24.2% lift in open rates for e-mails sent to consumers who only browsed the site.

Having these two types of e-mails arrive much closer to the time a customer abandoned a cart or browsed the site made all the difference, DeLanders says.

She says it is not clear if the increased open rates had an effect on J. Jill's delivery rate, which she says has always been very high. "We'll immediately remove a subscriber if they are deemed undeliverable," she says.

Personalization

Like J. Jill, travel firm Kensington Tours was looking for ways to get more of its e-mail subscribers to open more of its e-mails. Robin Brooks, marketing manager at Kensington Tours, says the company knew it had to go beyond snappy subject lines, and as a luxury merchant, sales or special deals were not its style.

Like a chain retailer that operates many stores around the country, Kensington Tours has 20 travel agencies operating under 11 brands, all offering getaways and tours. So Kensington, which uses e-mail marketing services and technology from Campaigner, concluded that adding a personal touch from each of its agencies to the appropriate e-mail list segments would get consumers to open.

"With a few of the brands we wanted to do the same campaign but change the logos and the e-mail addresses that they came from," Brooks says. Campaigner, she says, set it up so that she could automatically e-mail the 20 different lists the same content—but with different logos and agency information—from the appropriate travel agent's e-mail address.

Kensington Tours then sent a text-only, letter-like e-mail campaign to each of the individual travel agents' e-mail lists. The e-mails came from individual travel agents' e-mail addresses and addressed recipients by name. The message looked like a one-to-one message. "We got a 65% open rate on the e-mail with just text," she says. "Putting that personal spin on it makes all the difference."

Brooks declines to reveal what the travel firm pays Campaigner. Campaigner says it charges $200 per month for sending unlimited e-mails to up to 50,000 subscribers. For more than that it negotiates cost based on volume. Kensington Tours has more than 260,000 e-mail contacts, Brooks says.

The travel firm has achieved a return on its investment, she adds. Before using Campaigner the firm's e-mail click-through rate was 2%; it's now 3%, she says. Kensington Tours doesn't have delivery rate data from before it began working with Campaigner, but Campaigner says the travel firm's delivery rate today is 91.75%.

Symbols make a splash

In addition to personalization, another tactic that can boost open rates involves little hearts, shining stars, and all kinds of fun shapes and icons. These non-alphanumeric symbols started popping up in the subject lines of marketing e-mails last year.

The use of non-alphanumeric symbols can help a message stand out in a crowded inbox, Dutch Hollis, general manager of professional services at Knotice, says.

"Standing out is the first step in getting the treasured open, and while a trick like this works, it can't be used all the time," Hollis says. "There have been concerns that the use of symbols in subject lines heightens the risk of an e-mail being blocked as spam."

Knotice tested that theory, using identical creative with different subject lines—one with an icon, and one without—and found that both versions generated similar rankings on major spam filters. That suggests that symbols are not a barrier to delivery.

With that fear dismissed, Knotice recently tested symbols in subject lines for a client Hollis declines to reveal. "The open rate for the subject line with the symbol was 6.34%, while the open rate for the subject line without the symbol was 5.66%, representing a statistically significant lift for the subject line that included a symbol."

However, overuse of symbols will dilute their effectiveness over time, Hollis says.

Successfully getting e-mails into customers' inboxes and getting those customers to open the messages are the aspirations of every e-mail marketer. Fortunately for marketers there are many tactics, from seeking permission to send a second time to personalization to symbols to daily deals, that can help boost delivery and open rates, setting the stage for more effective e-mail campaigns.
