- 1. 1 The Big Rewards of Email Deliverability BY LEN SHNEYDER The Impact on Revenue of Choosing the Right Email Provider
- 2. 2 From the revenue generated by email marketing to increased customer engagement and reduced call center expenses, email has evolved to become a significant contributor to a company’s bottom line. But in order to capitalize on the benefits of email, it first needs to reach the intended recipient. Proactive approaches to deliverability are often put on the back burner and only revisited when a crisis arises, prompting the phrase “no one cares about email until it doesn’t arrive.” In fact, according to deliverability services provider Return Path, 17% of all sent email goes missing or lands in the spam folder. When you consider the impact of improved deliverability — increased revenue, customer growth and improved brand stickiness — deliverability pretty quickly moves up the priority list. However, ensuring the successful delivery of email to thousands of mailbox providers and ISPs is no easy task — it requires a highly specialized sending infrastructure built for today’s email needs. In this guide we’ll explore deliverability in today’s cloud and transactional email services market, the vis- ible differences between delivery platforms, and what those differences mean for a sender’s bottom line. EXECUTIVE SUMMARY The Direct Marketing Association of the UK attributes 18% of total company revenue to email marketing. According to Return Path, an average of 17% of all legitimate email lands in the spam folder or doesn’t arrive at all. Poor deliverability can be directly correlated to decreased revenue. The negative impact on revenue needs to be communicated clearly to build the business case for an optimized email delivery platform. SparkPost is the industry’s leading email delivery service with nearly 98% inbox placement — 15 points higher than the industry average, and 8% higher than the next best cloud infrastruc- ture vendor. SparkPost is from the company whose email platform delivers 25% of the world’s legitimate email. Think about what 1% of email delivered to the inbox is worth. What about 3%? How about 8%? What would you do to improve your deliverability by 8% if you knew that would be worth $100,000, $500,000, what about $1,000,000? To the top ten Internet retailers, an 8% increase could mean upwards of $13 Billion! But more on that in a moment... A SHORT HISTORY OF EMAIL DELIVERABILITY In the late 1990s, ISPs were contending with a massive increase in the volumes of spam — torrents of unsolicited commercial email flowed from botnets and unscrupulous senders, all the while growing exponentially. As a deliverability foot soldier, it wasn’t unusual to receive a call from AOL’s postmas- ter team asking you to back off, or limit connections, because they were contending with a massive backlog of spam that was crushing their gateway servers. These really were the dark ages for mailbox
- 3. 3 providers, ISPs and deliverability personnel. Weekly — and sometimes daily — anti-spam filter changes and updates by ISPs and mailbox providers turned delivery into an ever-shifting jigsaw puzzle. Legitimate senders were routinely caught in the crossfire, false positives abounded and the chore of protecting, let alone improving, deliverability to the inbox, was priority number one for a great many companies and Email Service Providers (ESPs). ESP customers often blamed the ESP for situations completely out of their control — the problem was exacerbated by mailers frequently switching their ESPs, mailing IPs and domains in hopes of improving their chances of landing in the inbox. In the mid 2000s, following the passage of CAN-SPAM and widespread adoption of “spam buttons”, deliverability truly became top of mind for companies that regarded digital marketing as the future of their business. Simultaneously, ISPs and mailbox providers established tools like the Smart Network Data Service (SNDSi ) and Junk Mail Reporting Partner Program (JMRPPii ) to make it easier for legitimate senders to communicate with postmaster teams and take advantage of ESP-centric tools that increased transparency and ultimately deliverability. All of this was aimed at improving the satisfaction, security and inbox experience of the end user, a mutual customer for ISPs and ESPs. Now, in the mid-teens, deliverability seems to have come to a point of stasis — titanic volumes of spam are managed through improved technologies that rely on user input (the democratization of inbox deliv- ery), sophisticated algorithms that better identify botnet traffic, email authentication, proprietary and/or third party black listsiii , sending reputation and other data-rich inputs that help ISPs discern “ham from spam”. However, the fact still remains that some portion of email never arrives to the intended recipient. Year after year, companies such as Return Pathiv , IBM and 250OK report that anywhere from 17% - 25% of legitimate email lands in the junk folder or goes missing. Missing 11% Inbox 83% Spam 6%
- 4. 4 The truth is that the industry has accepted its own futility — marketers are content delivering just 83% of their email to the inbox. Even if they’re in the 90th percentile, there’s still room for improvement. Upon further examination, the deliverability shortfall is nothing short of the willful abandonment of billions of dollars because senders don’t realize there are better routes to market. One option that can greatly impact a senders’ deliverability is the choice of sending platform. They’re not all alike, and its incumbent upon companies to understand the differences between in-house sys- tems, ESPs and the new crop of cloud providers that tout DIY API driven services. UNDERSTANDING THE IMPACTS OF DELIVERABILITY Although sometimes considered the hot-button topic of five years ago, “deliverability” is not an out- dated buzzword, it remains the chief concern of anyone sending email today. Engagement begins when email arrives — it’s where everything starts. From the en vogue idea of a 360+ degree view of the customer to multi-channel journeys, the common denominator of email in the inbox permeates all marketing strategies. If we forget for a moment about the revenue driven through successful email mar- keting programs and focus on transactional email then we have to view email as: • A cost-effective building block for startups • A tool to automate customer service • A system of record underscoring e-commerce • A platform for customer and product education • A political life line • A civic and emergency alert medium • The world’s most widely used communication channel • The most basic form of digital identification on which an internet persona is built Email is truly cross-platform, cross-device and cross- channel given the reliance of other channels on email and its highly portable format. The importance placed on email by startups can be clearly seen in how newly-minted companies nurture their nascent customer bases through simple transactional messages like welcome emails or the one- off announcement/newsletter. You can track the progress of companies based on the sophistication of their email programs — to compete in today’s market, and more importantly, in today’s inbox, you need data and you need to action that data. When data is actioned, companies transform their transactional messages into focused, data-driven triggers aimed at conversion and monetization. At this point, a com- pany’s digital messaging has truly come of age as it leverages customer behavioral insights harvested from the web, previous purchase history, social and mobile triggers like platform, cross channel intel, demographic and psychographic data to create contextually aware communications.
- 5. 5 No amount of data or analytics leveraged to create one-to-one targeted email will help if your email doesn’t arrive. If it’s in the spam folder you have a reputation or content problem — or both. More importantly, if it’s in the spam folder you have a revenue issue, making your choice of email delivery plat- form a critical one for your business. METHODOLOGY Before diving into the data, it’s important to step back and understand what we’re looking at. Most com- panies and marketers use a combination of deliverability seed testingv , click-through rate tracking and conversions as a measure of campaign and email marketing efficacy. Seed testing provides a reasonable estimation of actual performance, however, there’s no substitute for actual customer inbox data. For this report we sourced data from eData Source across all known transactional email services providers. These are actual production emails that landed in the inbox vs. the spam folder across a broad cross section of North American users. We tallied up the total number of records to understand the size of the sample we were actually working with, and this study is based on more than 75 million unique email records from actual customer inboxes. Our goal was to understand how deliverability changed from provider to provider across 3 major ISPs: Gmail, Yahoo! and Outlook.com (Hotmail). These three free mailbox providers are the largest mailbox providers on the planet and according to data from The Radicati Groupvi , account for nearly 30% of all email accounts globally. Most B2C mailers will have anywhere from 40-75% of their addressable mail file composed of the big three, representing not only B2C consumers but also hosting small business domains and their corresponding mailboxes. Gmail 425,000,000 / 38% Hotmail 420,000,000 / 37% Yahoo! 281,000,000 / 25% Number of mailboxes by free Mailbox Provider
- 6. 6 EMAIL DELIVERABILITY MEASURED — THE RESULTS Looking across the industry there are many different flavors of email infrastructure. From traditional ESPs that have grown complex segmentation and list management front-ends, combined with a wide array of strategic marketing services, to no-front-end, pure-API tools for sending email-at-scale, email has defi- nitely come of age. However, not every innovation has yielded stellar results, nor delivered the kind of performance that prevents revenue loss and customer attrition. The chart below covers the gamut of API-driven transactional email providers that either focus solely on transactional messaging or have evolved to provide both commercial and transactional email services. The common thread among this group is the freemium model most of them employ, and the lack of both the rich GUI front-ends and the marketing and strategic services that define a white-glove approach at the top of the ESP market. Each of the providers we reviewed employs one or more MTAsvii as their underlying delivery mechanism. They are not only challenged with solving the delivery of email-at-scale, but are facing deliverability-at- scale problems associated with sending email for many small mailers. From shared pools to reserved IPs for their marquee customers, every company involved in third party email delivery is forced to adapt their systems to meet their customers’ needs while complying with the complex practices, acceptable use policies and terms of service that define the many receiving domains hosting the world’s inboxes. Based on the analysis of recipient inbox data sourced from eData Source, we see a rather wide range in terms of inbox placement between Message Systems’ SparkPost on the high end of the scale and other transactional email providers. 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% SendGrid Dyn Mandrill Amazon SES Mailgun Google App Engine Cloud Provider Deliverabilityvi 68.6% 69.8% 83.6% 86.9% 87.2% 89.5% 97.8% Inbox Placement Percentage Cloud Provider Deliverabilityviii
- 7. 7 SparkPost, the cloud email delivery service from Message Systems, delivers incredible performance at the rate of 97.8% inbox placement. This puts SparkPost deliverability 8% above the next cloud infra- structure provider, and 15% higher than the average inbox placement defined by Return Path. Senders leveraging SparkPost see more of their email reaching their intended recipients — this kind of successes manifests as improved deliverability and a higher return on investment. Maintaining world-class deliverability at scale requires a level of competence in understanding the char- acteristics of email in transit, the signals ISPs read to identify spam, and architecting systems compliant with industry established best practices. In addition to over 15 years of development insight, experience and success, Message Systems built the Adaptive Email Network (AEN)ix to help automate delivery to the more than 12,000 global ISPs and mailbox providers. The AEN intelligently categorizes bounces, throttles email traffic in real time in response to sending conditions as they arise, and maintains over 2000 rules that optimize the delivery and sending of email. THE DOLLARS & CENTS OF DELIVERABILITY IMPROVEMENTS The underlying mechanisms, platforms and service you use to send your email matters — not only does it matter, it can be measured and contextualized based on lost or potential revenues. To understand the revenue opportunity embodied by undelivered email we have to understand the contribution email mar- keting makes to total company revenues. The Direct Marketing Association of the UK conducted a studyx in which they found the mean attribution of email to total digital revenues to be 30%. Additional findings within the paper position email market- ing revenues as 18% of total company revenue. 10% 20% 30% 40% 50% 60% or more 27% 44% 15% 8% 5% 10% 18%18% 11% 13% 10% 21% 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% 2012 2013 Porportion of email revenue to total digital revenue Porportionofrespondents Mean percentage of digital revenue: 2013: 30% What does email contribute to the business as percentage of digital business revenue?

According to their findings about 15% of marketers attribute 15-20% of their revenue to email: Now that we have a solid metric on which to base our calculations, 18% attribution to total company revenues, we can measure the revenue impact of undelivered email on the Top 10 Internet Retailersxii on the planet: Less than 5% 5.1% to 10% 10.1% to 15% 15.1% to 20% 20.1% to 25% 25.1% to 30% Greater than 30% Not sure 4% 14% 12% 17% 15% 16% 9% 12% 0.08 (Deliverability Lift of SparkPost over competitors) Deliverability Opportunity = Total Company Revenue xx 0.18 (TCR attributed to email) { }
- 9. 9 Email’s value extends well beyond branding and awareness; email is a primary driver of revenue. An 8% lift in deliverability could translate into more than $13 billion worth of potential sales! The question that marketers have to ask themselves is “how much is deliverability worth to me?” Just a 1% lift in deliver- ability across the top 10 Internet Retailers results in over $1.7 billion worth of potential revenue. Most companies we work with already know the value of email, or they at least have some idea as to how much revenue email drives for them. However, not everyone thinks about the lost opportunity of revenue from undelivered email. We routinely see happy customers enjoying a significant lift in their deliverability and revenue, pushing toward 10% — which at the end of the day is the difference in per- formance between SparkPost and the next cloud service provider. In today’s cloud-centric SMTP/API world change isn’t as hard as it used to be. Achieving significant lift and tangible business results can be achieved in a matter of months, if not less, even for senders with volumes in the billions of emails per year. Even if your volume hasn’t reached the billion mark, best-of-breed email platforms like SparkPost provide cost savings that manifest in the form of fewer resources necessary to improve deliverability through automated systems and almost 2 decades of email experience. SparkPost is also the industry’s most powerful API infrastructure for building email in the cloud.

- 10. 10 ENDNOTES i SNDS — The Smart Network Data Service gives mailers the ability to see performance data based on their outbound mailing IPs a day in arrears. ii JMRPP – Junk Mail Reporting Partner Program is a feedback loop established by Hotmail/Microsoft that allows companies that have been vetted to receive feedback loop complaints to suspend mailings to users who no longer want to receive email or have marked a message as spam. iii Most major ISPs and mailbox providers maintain their own internal blacklists. Landing on one of these blacklists is considered to be extremely problematic and indicative of poor mailing practices. On occasion a 3rd party blacklist such as Spamhaus.org is employed to further augment a mailbox provider’s ability to better identify abusive senders and curtail spam to the user’s inbox. iv http://returnpath.com/research/email-deliverability-benchmark-2014/ v Seed Testing is the act of including a batch of seed email addresses, commonly 10 per ISP that is to be tracked or tested, with a campaign, or before a campaign, to test the deliverability of a particular template or campaign at a given set of ISPs.
