Navigating complexity in digital advertising
Digital advertising is more fragmented and privacy-constrained than ever. How is 33Across helping marketers cut through that complexity to drive real outcomes, and what makes your approach distinct?

Users consume content across multiple devices and channels, making it difficult for marketers to identify and accurately target them with the right message. 33Across segments leverage AI-powered contextual and behavioral signals across privacy-safe environments to help marketers accurately identify audiences, whether they’re streaming content on their connected TV or researching products on their mobile device. What sets us apart is that we don’t just identify valuable audiences; we help marketers also target cookieless inventory and power it with real-time signals.

Globalization affects retailers in a number of ways. Complying with commercial laws wherever they have brick-and-mortar stores is one such impact. Navigating through privacy rules that impact e-commerce efforts is another. There is one blind spot in particular that deserves attention — sending shopping cart abandonment emails. I am often asked, “How are abandonment emails treated under the CAN-SPAM Act? Canada’s stringent Anti-Spam Law (CASL)?” “Can I even send abandonment emails to my Canadian customers?” What are cart abandonment emails? But let’s back up… What is an ‘abandonment’ email anyway? In the email space shopping cart abandonment refers to a particular type of automated mailing used to re-engage an online customer. The most common example is one where a retailer notices that a customer has left an item sitting in their shopping cart, and proceeds to send a reminder with a coupon to complete the order. To fully understand privacy compliance pitfalls with this technique, in the U.S. and beyond, we need to unpack what happens before the abandonment email is sent. Email marketing shopping cart abandonment compliance Abandonment messages are almost always ‘commercial’, particularly if they incentivize a shopper to complete their purchase. In compliance parlance, we call this encouraging the continuation of a commercial activity. In contrast, an order confirmation typically provides factual information about a commercial activity. Under most anti-spam laws, particularly under CASL, marketers need to ensure abandonment messages are not unsolicited. Triggering should account for: Appropriate consent covering email marketing to new or ongoing online relationships. Scrubbing the customer’s email address against your unsubscribe/suppression lists before sending a solicitous message. (This is true under any anti-spam law.) For more information about CASL-compliant consent record keeping and related best practices, you can navigate to the Canadian Radio-television and Telecommunications Commission. Maintaining compliance with online tracking Abandonment emails rely on online retailers tracking their customers’ activity on their websites and tying online behavior back to the email addresses using the same behavioral targeting technologies as those used to deliver Interest Based Ads. This jump across engagement channels to remarket to customers can raise privacy concerns, so online retailers need to pay attention to their privacy compliance obligations. Cross-channel marketing privacy protections Guidance covering privacy policies and practices issued by the Federal Trade Commission are informative and I encourage you to review these with your law department. If you operate outside the U.S., privacy protection laws like Canada’s Personal Information Protection and Electronic Documents Act (PIPEDA) may set out additional obligations with your cross-channel marketing efforts. PIPEDA’s definition of commercial activity, which includes remarketing Privacy Commissioner’s findings under PIPEDA in relation to remarketing Privacy Commissioner’s guidance on online behavioral advertising, the technology of which informs triggered emails Under PIPEDA and similar international privacy regimes, cross-channel marketers will need to (i) clearly and conspicuous inform website visitors that their online activities may result in personalized marketing, (ii) offer a way to opt-out of such tracking, and (iii) obtain individuals’ prior express consent with tracking involving sensitive personal information such as health data How to manage cross-channel marketing compliance risks As privacy protection regimes around the world continue to mature and absorb rules covering marketing, online retailers need to start adding new vocabulary to their privacy compliance lexicon. For example, shopping cart abandonment efforts produce ‘cross-channel re-marketing campaigns triggered by an identifiable individual’s online behavior.’ While this is a mouthful to say, viewing your engagement efforts through this lens will help you manage compliance risks.

Early successes include revenue increases, global partnerships and fundraising NEW YORK, March 16, 2017 /PRNewswire/ – Tapad's entrepreneurial mentorship initiative, the Propeller Program, has seen extremely positive results since it began in September 2016. The five early-stage startups selected from Norway have gained momentum in establishing a U.S. presence. Tapad, now a part of Experian, is the leader in unified cross-device marketing technology. The company was acquired by the Telenor Group in 2016. Among the successes within Propeller: Xeneta, the leading ocean freight price comparison platform and contracted rate database, has raised an additional $12M in funding since beginning the Propeller Program. Before the end of 2016, the company had exceeded its revenue expectations by nearly 30 percent, proving the European-focused business could succeed in the American market. "Aside from directly impacting our revenue, the Propeller Program has provided us with incredible access to a countless number of external resources, including subject matter experts from the fields of fundraising, public speaking, corporate structuring and immigration law," said William Di Ieso, GM of North America for Xeneta. "We remain extremely grateful for the opportunity and exposure the program has provided for Xeneta." Bubbly, an in-store real-time engagement tool for non-buyers, now has clients on four continents.

"The mentoring sessions have been very valuable and have given us guidance as to how to best enter the U.S. market," said Marianne Haugland Hindsgaul, Bubbly CEO and co-founder.
