How to Maintain Consistent Email Appearance Across Devices

You’ve probably experienced it yourself: an email that looked perfect on your laptop but turns into a jumbled mess on a smartphone. Distorted columns and broken CTAs don’t just frustrate readers; they hurt clicks and conversions.

To help you avoid these issues, we put together this guide that covers the common reasons for inconsistent rendering and how you can prevent them from happening.

What causes inconsistent email appearance across devices?

The root of the problem lies in how devices interpret layout, scaling, and structure when rendering your emails. There are multiple reasons why this happens.

• Screen size variation: Desktops, tablets, and mobiles have different widths. A layout that fits well on one can easily overflow or collapse on another.

• Non-responsiveness: Non-responsive templates don’t adjust or scale based on the screen size, so content either overflows or gets squeezed.

• Image inflexibility: Hard-coded image sizes or poor compression lead to stretched, pixelated, or misaligned visuals.

• Unoptimized spacing and font sizes: What looks balanced on a large screen may appear cramped or oversized on a small one.

How to maintain a consistent email appearance across devices

There are multiple aspects of the emails that you need to look at when you’re trying to make your email appear consistent across different devices. Mailmodo lets you optimize each aspect of your email so it appears consistent and professional on any device. Let's explore each aspect one by one:

1. Layout

• From the Mailmodo dashboard, go to Templates → Pick a template or start from scratch.

• In the Layout tab, select your preferred layout. Mailmodo offers your seven prebuilt layouts, but pick the single-column layout ones for the best cross-device consistency.

2. Images

Depending on your layout, you can add images to various sections of your email, including logos, banners, product shots, and icons.

Here are some best practices to follow:

• Set image widths to 100% so they scale proportionally on smaller screens.

• Maintain correct aspect ratios to avoid stretched or squished images: For example, use square for logos and icons, and landscape for wide visuals.

• Use high-resolution images compressed under 500KB to retain sharpness without slowing load times.

• Add white outlines around logos or icons for visibility in dark mode.

3. CTA

• Ensure your CTA buttons are large enough to tap easily on mobile by selecting large size and full width.

• Place CTAs in the first fold so they are visible on both mobile and desktop.

4. Cross-device testing

• Use the desktop/mobile toggle (icon at the top of the editor) to check how your design appears on both device types.

• Send a test email and check it across devices to ensure layout, images, and CTAs appear correctly.
