Mobile Formatting
In today's world, your emails must look good on all devices. With that in mind, the Email Builder Inline Editor provides a special section for mobile formatting.

Email Mobile View Configuration Best Practices:
When configuring mobile emails, you need to pay close attention to a few key areas that contribute to the overall usability and effectiveness of your emails:
- Use a Single-Column Layout: Single-column layouts work best for mobile as they are easier to scale down for smaller screens. Multiple columns can get cluttered on a mobile screen and may be confusing for users to navigate.
- Optimize Images: Ensure your images are of high quality but also keep the file size small for quick loading. Consider using responsive images that will automatically adjust to fit the screen they're viewed on. Don't forget to include alt text for accessibility.
- Touch-Friendly Buttons: On mobile devices, your CTAs will most likely be tapped with a finger rather than clicked with a mouse. Ensure your buttons are large enough to be easily tapped - a minimum size of 44px by 44px is recommended.
- Limit Text Amount: On mobile devices, lengthy text can be daunting. Be concise and break your text into small, manageable chunks. Make use of bullet points and subheadings for easy readability.
- Use a Responsive Email Design: This will ensure that your email will automatically adjust to fit the screen of any device it's viewed on.
- Preview and Test: Always preview and test your emails on different devices and email clients to ensure they display correctly.
- Include White Space: White space isn't wasted space. It makes your email cleaner and easier to read on a small screen.
- Font Size and Style: Keep your font size large enough to be readable on small screens. A size of 14 for text and 22 for headlines is often recommended. Avoid fancy fonts that might be difficult to read.
- Clear and Concise CTAs: Make sure your call-to-action is clear, concise, and easy to find. The best place for a CTA button is generally in the middle of the screen.
- Optimize Subject Lines and Preheader Text: Keep your subject lines short and engaging, and utilize the preheader text to provide a summary or teaser of your email content. It's also a good idea to A/B test different versions of subject lines to find what works best for your audience.
- Opt for Plain Text Over Images: Some email clients may not automatically display images. To ensure your message gets across, use text as much as possible and only use images when necessary.
- Unsubscribe Option: Make it easy for recipients to opt out of your emails. Not only is this a legal requirement, but it also improves user experience.
- Accessibility: Make your email accessible to everyone. This includes using larger fonts, ensuring good contrast between text and background, and including alt text for images.
Remember, the best practices for mobile email configuration may vary depending on your specific audience and the type of content you're sending. Always test different approaches to see what works best for your audience.
