If Google acquired Sparrow, the creator of the e-mail client for Mac and iPhone, the media must still hold promise for marketing. Email click-through rates averaged 5.4% in 2011 and year-to-date in 2012, up from 4.5% in 2009, according to a recent study from Silverpop.
The 2012 Silverpop Email Marketing Metrics Benchmark Study suggests that more consumers use multiple devices to read and access email. It has become common for users to scan emails on a mobile device and then view and act on the messages later via desktop or laptop computers. If images were enabled or links clicked with images blocked or disabled across devices, then an open rate would be captured at each access point.
The study looks at metrics in 12 verticals for open rates, message size, list churn, unsubscribe and complaint rates, but for the purpose of this article the focus turns to click-through rates.
Computer Software, Media & Publishing and Consumer Services performed best. For example, the Computer Software segment had the best unique open rates, averaging nearly 25%. The study attributes the higher click-through rates to lighter sales content and related messages, as well as heavier emphasis on news, information and educational materials.
These verticals also performed well with click-to-open rates -- more than double the average and six times higher than bottom performers. Splits among industry verticals were similar to those in the click-through category.
Clicks per clicker measures how often the recipient of the email clicks links in the same message. It captures clicks of a specific link multiple times or clicks to more than one link in the email message.
The Silverpop study suggests that the difference between high and low performers were less pronounced compared with other categories, but the top quartile still tallied 17% more clicks per clicker than average. The Computer Hardware and Computer Software industries performed best, with the latter the only one to top three clicks per clicker.
