I don't know about you, but when I get an email on my phone and have to squint my eyes to try and make out the words, I hit delete. The emails I'm deleting aren't spammy, unpersonalized messages -- they're just poorly optimized for mobile. And I'm not the only person who does this.

In fact, at the time of this post, 49% of poll participants on LifeHacker voted that out of the emails they receive each day, only 25 or fewer of them were spam. That was the smallest bucket that the 3,304 voters (thus far) could choose from.

If only a small portion of emails received each day is actually spam, that means you have a chance to actually compete for attention in a user's inbox. And your mobile readiness may just be what makes or breaks you.

The following 13 stats explain why.

Case #1: Mobile Email Usage Is Increasing

4) By the end of 2018, worldwide mobile email users are expected to total over 2.2 billion. By this time, 80% of email users are expected to access their email accounts via a mobile device. (Source: Radicati


Takeaway? Prepare mobile-friendly emails.

More and more mobile users are accessing emails through their mobile devices. In order to effectively see results from your email marketing campaigns, you'll need to ensure each of those emails is ready for reading by the 74% of smartphone owners who use their mobile phones to check email. 

Case #2: Businesses Aren't Preparing for Mobile

Takeaway? Beat the competition with mobile optimized emails.

Despite rising consumption of email on mobile devices, many businesses refuse to address this shift. The technical and expertise changes needed to become an early adopter prevents marketers from investing in a mobile email strategy. Don't let that be you! Mobile phone owners aren't starring emails on their phone to be read later. Once they read it once on their phone, they're done.

You can either be another unoptimized sender, or you can get on the mobile trend before the competition does and start winning deals faster through mobile. Fortunately many tools are available to show you where your email traffic is coming from, including Signals, a free email tracking tool that will show you who is opening your emails and what device they opened it on.

Takeaway? Use mobile email content to make money. 

Whether you're an ecommerce business directly generating sales from email sends or a B2B company sending a dedicated marketing offer to increase lead flow, mobile-friendly emails can benefit your bottom line. 

Now I'm not going to lie, optimizing for email can take some time. But investing just a little more time when preparing your mobile campaigns can go a long way in benefiting your business.
