6 Tips to Create Better Mobile-Friendly Emails
With 68% of emails being opened on mobile devices, creating a mobile-friendly email, especially for online retailers, is no longer just a nice thing to have. It is a must-have.
Email marketers can no longer ignore mobile devices and tablets. They represent a massive part of all email interactions and, consequently, revenue.
In this article, we will explore the essential elements for creating a successful mobile email campaign and those are:
• Subject line
• Pre-header text
1. Measure the Length of the Subject Line
Subject lines are the first things a recipient sees and they determine whether the recipient will open the email, so the importance of subject lines can’t be overstated. As we all know, different mobile devices show a different amount of characters for the subject line, but the rule of thumb is having around 25-30 characters. By contrast, according to Return Path and their research after analyzing over 2 million emails, most subject lines are between 41-50 characters long.
Although keeping the subject line to 35 characters is challenging, you should definitely try to do it. Put your main message at the very beginning so it shows up on mobile devices and keep the subject line 5 or 6 words long. Here are some examples of subject lines where 35 characters are viewable, but the rest of the characters (marked in red) are not visible on most mobiles:
• Still Looking for Boots?
• Introducing the New Women’s Winter Wellie!
• New Work Boots and Hunting Boots Now Available!
• New arrivals: Muck Boots for Hunting & the Outdoors!
• New Woman’s Colors in Winter Boots Now Boots Now Available!
2. Optimize Your Pre-Header Text
A pre-header is the short summary text that follows the subject line when an email is viewed in the inbox. In other words, it’s the first line of the copy of your email, which can be very useful when it comes to mobile-friendly emails.
The pre-header area is a prime piece of inbox real estate that’s begging to be optimized and many retailers fail to do so. They support the subject line by further hinting at what the email contains before the user opens it. Here’s an example in Gmail, you can see the pre-header text in grey:
The shift to mobile has made the use of pre-header text an important consideration for anyone using email to grow sales and revenue. Along with the subject line, the pre-header text is the first thing subscribers come into contact with when they receive your email campaign. It is an extension of your subject line and it should be short in order to ensure it displays properly across different devices.
Additionally, don’t forget to include a call to action in your pre-header as it’s a simple but effective way to increase your open rates.
What’s the average length of a concise yet meaningful mobile-friendly pre-header? According to Litmus, it is best to keep to 35 characters at most, so as to ensure the pre-header gets shown in full on most mobile devices.
3. Think Twice Before You Upload Your Images
Email marketing best practices advise against creating heavily image-based emails. Why?
Well, not all mobile devices display images by default so it’s better to plan for an “images off” experience. Make sure that your email will still make sense even when your images don’t show. Here is a list of other reasons for thinking of images as optional rather than the contrary:
• Some email clients don’t autoload images, so clients may see a blank screen or broken images
• Images usually take longer to load than text, so the reader might not wait for them
• Low image/text ratio can result in your email getting pushed into the spam folder
However, an image says a thousand words, and not to mention how good gifs are for engaging users. So here are some recommendations on how to include them into your mobile-friendly email correctly:
• Keep image or gif files sizes small (so they won’t load for too long)
• Use images to support the content, so that if they don’t load, users still have an idea of what your email is about
• Make sure that any item pictured in your email is directly linked to its corresponding product page.
4. Keep It Concise
When writing a mobile-friendly email, it’s essential to keep it short and concise. Due to the fact that the overall mobile screen size is small, you need to engage readers as efficiently as possible. To achieve this, create short, scannable, and consumable content using short paragraphs, bulleted lists, highlights, headers, etc.
Here’s a newsletter that illustrates all of the tips above. The copy is short but compelling enough to entice the reader to click and read the article, and it makes it easy for recipients to find what they’re looking for by using headings or bullets.
A mobile user’s experience is unique as readers must remain compelled to scroll from the headline downwards in order to continue reading. This makes it important that your structure optimizes the ease of this process, providing logical structuring. If the web copy is skimming the cream off the top of the milk then the mobile copy is skimming the cream off the cream!
5. Include Thumb-able Buttons
As we all know, the whole point of sending emails to your customers is to inspire action: make them view your store, browse for products and (hopefully) buy some. Consequently, you need to include a call to action (CTA) not only in your subject line but also in the main body of your email. In general, all of your CTAs should be:
1. Kept front and center – Place them near the top of your email to make it as mobile-friendly as possible
2. Clear & Big – Make CTAs big, bold, and blindingly obvious (at least 44 x 44 pixels)
3. Isolated from other CTAs – Prevent your potential customers from clicking the wrong link.
To ensure maximum clickability, leave breathing and clicking room. You can see this in the example below:
6. Test Emails Across Multiple Devices
Finally, when you’ve already created your mobile-friendly email, make sure you test it across multiple mobile devices. We recommend using Email on Acid, which allows instant previews on multiple different devices.
All in all, these are six essential but easy-to-implement tips to help you create mobile-friendly emails your clients will love to open and take action on:
1. Keep your subject line around 25-30 characters
2. Pre-header is an extension of your subject line; however, keep it short and include simple CTAs
3. Focus more on descriptive content, trying not to create too image-heavy emails
4. Create short, scannable, and consumable content using short paragraphs, bulleted lists, highlights, headers, etc.
5. Make your CTAs blindingly obvious and spaced out from other CTAs by keeping them front and center
6. Don’t forget to test your mobile-friendly email across multiple mobile devices before launching it
