Definition
Video embedding refers to the techniques used to include video content in email campaigns. True video playback within the email client is limited (supported mainly by Apple Mail and some mobile clients), so most video email strategies use alternative approaches — animated GIF previews, poster images with play buttons, or AMP carousels with video support.
Video in email can increase click-through rates by 50-300% compared to text-only or static-image emails, making it one of the most effective engagement drivers available.
Video Implementation Methods
| Method | Description | Support |
|---|---|---|
| Poster image + play button | Static image with a play button overlay that links to the video page | Universal (all clients) |
| Animated GIF | Looping video preview as animated GIF | Widespread |
| AMP video | Native video playback via AMP for Email | Gmail only |
| Video tag | HTML5 | Apple Mail, Outlook iOS/Android, Samsung Mail |
| Cinemagraph | Subtly moving image (partial animation) | Widespread (as GIF) |
| YouTube preview card | YouTube thumbnail with branding | Universal (links to YouTube) |
Best Practices for Video Emails
- Use a poster image: Always include a compelling static fallback image
- Add a play button: Visual indicator that the image is clickable for video
- Keep videos short: Under 60 seconds for pre-click previews
- Host externally: Host video on a landing page, YouTube, or Vimeo
- Track clicks: Track the play button/thumbnail click, not "video plays"
- Include text context: What the video is about and why they should watch
- Test rendering: Video elements behave differently across clients
- Optimise file size: Keep GIF previews under 1MB, ideally under 500KB
Video Placement in Email
| Placement | Effect | Best For |
|---|---|---|
| Above the fold | Maximum visibility, high play rate | Hero content, main CTA |
| In content | Contextual relevance | Tutorials, product demos |
| Post copy | Reinforcement after key message | Testimonials, case studies |
| CTA button | Text link to video as secondary action | When images are blocked |
| Video carousel | Multiple videos in one email | Product range, series |
Measuring Video Email Performance
- Play rate: % of email recipients who click to view the video
- Video completion rate: % who watch the full video (on landing page)
- Click-to-play ratio: Clicks on video elements vs total clicks
- Email click rate: Overall CTR with vs without video
- Conversion from video: % who purchase after watching

Above the Fold in Email
Above the fold in email refers to the content visible to a recipient before they scroll, a critical area for first impressions and primary calls to action.
Accessible CTA (Email)
An accessible CTA is a button or link coded with sufficient colour contrast, visible focus states, descriptive screen-reader text, and a minimum touch target of 44×44 pixels.
Adaptive Design
Adaptive design in email uses predefined layouts that adjust to specific device or client widths, rather than fluidly resizing to every possible screen.
AI-Generated Content in Email
AI-generated content in email is copy, images, code or subject lines produced by artificial intelligence tools to speed up campaign production and testing.
AI Inbox Summary
An AI inbox summary is an AI-generated digest that condenses unread email — often highlighting news, actions and senders — changing how clearly your marketing email reaches and engages subscribers.
Alt Text
Alt text is the written alternative to an image in an email, displayed when images are blocked, slow to load, or consumed by screen readers.
Frequently Asked Questions
No. Native HTML5 video playback is supported only by Apple Mail, Outlook for iOS/Android, and Samsung Mail. Gmail (web and app), Outlook for Windows, Yahoo Mail, and most web-based clients do not support video playback within the email. The poster-image-plus-link approach works universally.
There is no single best format because support varies. Animated GIF is the most widely supported format for showing motion in email. For actual playback, MP4 (H.264) is the most compatible video format for the limited set of clients that support native video.
A video file embedded as an attachment will likely be blocked or trigger spam filters. Video content hosted externally and referenced via link is safe. Animated GIF previews are safe for deliverability. Avoid large file sizes, and never attach video files directly to the email.
