If there was any doubt that we’re in the midst of fundamental changes in consumer buying behaviors, the results from the opening days of the 2017 holiday season have put such questions to rest.

Movable Ink, a firm that enables content personalization within e-mails, has just published some insightful statistics it compiled from Thanksgiving weekend last month.  Movable Ink logged nearly 438 million e-mail opens between the Wednesday before Thanksgiving and the following Cyber Monday. What did it find?

To start with, it found that recipients engaged with them.

Of the e-mails sent on Black Friday, nearly 50% achieved read lengths of at least 15 seconds. On Cyber Monday, the results were nearly the same (~46%).

Fifteen seconds may not seem like a long time to engage with an e-mail, but it’s light years compared to what is often experienced in consumer e-retail.

Movable Ink also found that the majority of the e-mails were opened on smartphones — far outstripping desktops and tablets:

• Smartphones: ~53% of e-mail opens
• Desktop computers: ~25%
• Tablet opens: ~16%

An equal 53% of conversion actions happened on smartphones … but desktop conversions proved to be higher than their open stats, and e-mails opened on tablets were much less likely to experience conversions:

• Smartphone: ~53% of e-mail conversions
• Desktop computers: ~38%
• Tablets: ~8%

Consumers were certainly in a buying mood over the holiday weekend, with purchases averaging between $120 and $140 on each of the four days of the long weekend:

• Black Friday: An average of $124 spent
• Saturday: $120
• Sunday: $119
• Cyber Monday: $141

However, while smartphones led in terms of e-mail engagement, when it comes to actual dollar sales smartphones come in last – by a country mile:

• Desktop computers: ~$162 average holiday weekend total spend
• Tablets: ~$107
• Smartphones: ~$85

We can acknowledge that smartphones have become the most important method for reaching consumers with product content, coupons and special offers.  And yet, significantly more purchasing continues to happen on desktops.

One takeaway is that for all of the convenience smartphones purport to provide, the purchasing experience on mobile devices doesn’t yet match the experience on desktop computers.

It would also help if there was more similarity between the purchasing process sellers are delivering across all platforms. That continues to be a missing ingredient with some sellers, and it’s likely explaining at least some of the dampening effect on mobile sales revenues.
