The Best Video Formats and Sizes for Email Compatibility

by

Including videos in emails can greatly enhance engagement and convey information more effectively. However, not all video formats and sizes are suitable for email compatibility. Understanding the best options ensures your videos display correctly across various email clients and devices.

  • MP4 (MPEG-4): The most widely supported video format across email clients. It offers good quality with relatively small file sizes.
  • WebM: An open-source format supported by modern browsers, but less compatible with some email clients.
  • OGV: Supported mainly by open-source browsers; not ideal for email use due to limited support.

Among these, MP4 is the most reliable choice for embedding videos directly into emails or linking to videos hosted on external platforms.

Optimal Video Sizes for Email

Keeping video sizes small is crucial for email performance. Large files can cause slow loading times or prevent emails from being delivered. Aim for videos that are under 5 MB whenever possible.

  • Width: 600 to 800 pixels – fits well within most email layouts.
  • Height: Adjust proportionally to maintain aspect ratio, typically around 340 to 480 pixels for standard videos.

Best Practices for Embedding Videos in Emails

  • Use a static thumbnail: Embed a static image with a play button overlay as a fallback for email clients that do not support video playback.
  • Link to videos: Instead of embedding, include a thumbnail linked to a hosted video on platforms like YouTube or Vimeo.
  • Test across email clients: Different clients have varying levels of support for video. Always test your emails before sending.

By choosing the right formats and sizes, and following best practices, you can ensure your videos enhance your email campaigns without compromising deliverability or user experience.
