Retailers are kicking off the holiday season earlier and earlier each year, however Black Friday and Cyber Monday remain key focal points of the holiday marketing season. Brands that succeed this time of year need to connect with customers on their unique shopping journey, providing the right offer at just the right time for the greatest impact, making every interaction count.
Thanks to the scale and performance of the Salesforce Marketing Cloud, we delivered another record two days for our customers this Black Friday and Cyber Monday. This year, our customers sent more than 2.3 billion emails using Marketing Cloud on Cyber Monday, which is a 44% increase over Cyber Monday 2014. It is also a 77% increase over our daily average in November, where we sent more than one billion messages 23 days in the month. Marketing Cloud topped out at a whopping 191 million emails sent in a single hour on Black Friday.
Additionally, with people constantly on the move, retailers are leveraging mobile messaging. Our customers sent 16.2 million SMS, MMS messages, and push notifications using Marketing Cloud on Black Friday alone.
Not only did we deliver a record amount of message volume, our customers delivered more personalized communication to their customers using our predictive intelligence capabilities. Marketing Cloud predictive intelligence leverages data science and machine learning to automatically determine the next best offer, product, or content for each customer and delivers it across all channels. Predictive content drives an average of 25% increase in email conversion. On Cyber Monday, Marketing Cloud predictive intelligence powered 55 million unique predictions, with a peak of 1,100 predictions per second. On Black Friday, we powered 48 million predictions. These volumes represent a 67% increase over last year.
