And with potential returns of up to 4400%, it has become the primary focus for digital marketers.

28. 78% of teenagers still use email, even-though social media messaging apps are on the rise.

Mobile Hacking via Email

Email remains the easiest way to hack someone. Reports indicate an increasing number of accounts hacked on a daily basis.

This may be due to the fact that mobile email transactions have increased in recent years. Users tend to leave their data unprotected and open to attacks.

Best Practices for Mobile Email Optimization

With numbers suggesting that two-thirds of the population open emails on a mobile device, mobile-friendly design is not just something that is good to have – it has actually become a necessity.

And not only that, but a poorly written copy and badly optimized images within the email itself make it look unappealing. And users tend to directly delete unappealing emails.

Mobile-friendly email designs are important as the number of emails sent from mobiles have increased, and here are a few of the best practices for mobile email optimization and utilization:

1. Subject line length display.

Mobile devices show just 25 to 30 characters while desktop computers display a total of 60 characters of the email’s subject line.

Therefore, take this into consideration when optimizing email content for mobile devices.

2. Use a pre-header text.

A pre-header text is the first line of text copy in your email. This line serves as support to your subject line.

Mobile email statistics indicate that many people often ignore this or simply overlook it. However, it can be quite handy when it comes to mobile-friendliness. The reason behind it, is that pre-header text is often too long or complicated, making the reader scratch his head at what he or she is reading.

3. Make sure your text is clear and precise.

When writing the copy for the body of your email, make sure to keep it simple, to the point and very concise.

Short, smaller chunks of text are easily consumable and make it easier for your guest to read and navigate through your email. It will also prompt them to take action.

4. CTA needs to be centered.

This goes hand in hand with the previous point. A badly placed CTA can reduce the number of mobile email conversions.

With a simple copy text, you can get the message across quite easily and address the readers’ issues. Add a clear and centered CTA, so that the user can see it immediately and be prompted to click on it.

5. Use adequate and optimized images.

Every small device has a default way of displaying images. Do take this aspect into consideration when adding images to email messages.

Final Thoughts

Ever since the introduction of smartphones to the world, email marketing has found its way into these small devices, making itself a huge part of people’s everyday lives.

Neglecting this trend can be detrimental to a company’s success in acquiring new customers or promoting their services or products.
