Responsive email tips

1. Design in a single column so that it looks flawless even on clients like Gmail app.

2. Design with finger targets in mind. Keep the width to a minimum of 320 to 550 pixels, especially for small screen optimization.

3. Keep the CTA easily tappable with a minimum size of 44 pixels.

4. Use white-space wherever possible so that readers can skim through the content easily.

5. Keep the header clean. Put the navigation (if any) in the footer. This will let users see the main information in the first scroll.

6. With increasing Apple loyal readership, make sure your mobile email is optimized for retina devices.

7. Don't crowd links together and if possible keep text links in different rows and convert them to buttons for mobile view.

8. Provide tappable (call to function) phone numbers for mobile letting the users call whenever they need directly from a single tap

9. Limit subject lines to 30 characters or less

10. For the desktop view, use image width of minimum 480 pixels so that when the same is scaled on mobile it doesn't get blurred.

11. If you're a beginner, don't just scale images but swap in your media queries.

12. Restrict the height of your emails, as subscribers like to skim through shorter emails else they skip reading.

13. Keep all the important CTAs above the fold.

14. Test your responsive email design and make sure it's compatible across the major email clients.
