Bulletproof Email Call-to-Action Best Practices
Design accessible, mobile-friendly call-to-action buttons that render consistently across desktop Outlook and modern mobile mail apps.
Desktop Outlook VML Fallback
Word rendering engine in Outlook desktop ignores CSS border-radius and background colors. VML shapes ensure solid buttons everywhere.
Safe URL Verification
Built-in protocol validation blocks malicious scripts, local IPs, and insecure schemes from contaminating outgoing email links.
High-Contrast Tap Targets
Generous padding and accessible color contrast ratios provide effortless tapping on touchscreens and mobile devices.
Plain-Text Fallback
Every generated button includes a clean text equivalent so text-only email recipients still see your action link clearly.
