20 Mobile Email Marketing Stats That’ll Make You Better at Your Job

By 2022, Statista anticipates that more than 333 billion emails will be sent each data.

To give you an idea of how big that number is, if each email were a star, the cluster would be 50% bigger than the Milky Way Galaxy.

I hope I’m not the only one who thinks the statistic above is mind-blowing.

At this point, email has proven to be a major communication tool for both consumers and marketers. But, as this channel has thrived, mobile technology. such as smartphones and tablets, has also become much more abundant in society. 

And while you might think you have a solid email strategy, a huge portion of your audience might be missing out on your lead-generating content if your emails aren’t mobile optimized.

Even back in 2016, when slightly less people had smartphones, most of the consumer population would disregard or delete emails that weren’t mobile optimized. Today, mounting research shows that mobile optimization is even more vital to your email marketing strategy. 

But with so many resources, oftentimes in the form of extensive reports, it can be hard to find the time to keep track of important industry stats and information, such as that around mobile optimization.

To help you recognize why you need to optimize your email strategy for mobile, I’ve put together this list of essential email marketing stats that you should keep in mind.

First, I’ll begin with a few general stats that highlight why you need to embrace email marketing in the first place.
