1. Why Responsive Design Is Essential in 2025

Email is opened on mobile more than ever—over 70% of all opens now happen on smartphones and tablets. If your message isn’t optimized for small screens, you risk losing clicks, sales, and trust in seconds.

Your choice of email builder plays a huge role in whether responsive design is effortless or a frustrating chore. Some tools handle mobile layouts beautifully; others leave you scrambling to fix broken sections before hitting “send.”

2. What Responsive Email Design Really Involves

Responsive design means your email layout automatically adjusts to any screen size, keeping it readable and clickable everywhere. It’s not just about shrinking content—it’s about rethinking how it’s displayed.

Key elements include:

• Flexible layouts that adapt without breaking.
• Images that scale without losing quality.
• Legible text on both desktop and mobile.
• Column stacking rules that make sense for mobile reading.

A smart email template editor should let you control these details without needing to touch complex code—though having that option is a bonus for advanced users.

3. How Different Email Builders Tackle Responsive Design

Here’s the truth: not all email builders treat responsive design equally.

• Entry-level editors — Offer fixed-width templates that may look fine on desktop but often break on mobile.
• Mid-range tools — Provide drag-and-drop editing with some mobile optimization, but limit customization.
• Advanced platforms like Stripo — Give you complete control with both visual and code-based editing, ensuring flawless rendering on any device.

The difference between “passable” and “polished” often determines your campaign’s success.
