Follow these five steps to make your emails mobile-friendly:
1. Use a one-column layout. Vertical scrolling is more natural to mobile users.
2. Use larger fonts, bigger buttons and high-contrast colors. Make it easy for readers to differentiate your email's elements.
3. Include a link in the pre-header. The link should take readers to a text-only or—better—mobile-optimized version of your email (essential if you want to influence Blackberry users).
4. Keep emails short. Edit ruthlessley and use attention-grabbing calls to action. Your emails will be read during brief intervals of downtime.
5. Link readers only to mobile-friendly Web pages. It's futile to send readers to a Web page that can only be read on a desktop.
