All of our block components within our template builder are tested and supported by the following email clients on both desktop and mobile:

• Gmail
• Apple Mail
• Outlook
• Yahoo! Mail
• HEY
• Superhuman

Sample test run on some of the clients and devices supported by Waypoint.

Limitations:

• While we fully support modern clients, we provide graceful fallbacks for older or less popular email clients.
• Certain block options with responsive styling (eg. stacking columns on mobile) are only supported on modern email clients. Learn more about media query support on emails.
