Mobile conversion has officially crossed the chasm. With reports showing that mobile purchases drove 37% of sales on Black Friday and 40% of sales on Cyber Monday, mobile is no longer just an engagement channel, but a true revenue channel.

That is, at least, for the retailers who have their messaging strategy on point.

Knowing push notifications would be sent in high volume, top retailers like Target, Walmart, and Tradesy began sending holiday push messages up to three weeks before Black Friday to prime their app-enabled shoppers with promotion previews, countdowns, and more.
