VeloMail is a free Chrome add-on designed to enhance the mobile viewing experience of sales emails composed in Gmail and Outlook. This tool provides users with a live mobile preview of their emails, ensuring that what they send is visually optimized for mobile devices. As over half of sales emails are opened on phones, VeloMail's functionality is crucial for effective communication. It activates automatically when composing emails, displaying a real-time phone frame that updates as users type, and it includes a dark mode option for better visibility.

In addition to the live preview, VeloMail offers pre-flight tips to help optimize emails before sending. These tips include checks for subject line length, ensuring the call-to-action is above the fold, and verifying tap-friendly link spacing. A color-coded subject line counter is also included to prevent cutoff issues. VeloMail requires no setup, operates entirely locally to maintain user privacy, and offers both a free plan with limited sends and a lifetime plan for unlimited access.
