Video is no longer just an option in digital marketing, it’s essential to engage audiences and drive conversions by 20-30%. However, one main issue still stands for marketers: how does video perform across different devices and email clients? Understanding the supported formats, device considerations, common challenges, best practices, and data usage for using video in email is crucial to deliver high-quality content, effective video email campaigns.
Why Video in Email Matters
Email remains one of the most reliable marketing channels to directly communicate to customers and drive conversion. Video in emails can increase open rates by up to 19% and click-through rates by 65%, while reducing unsubscribes by 26%. Video is an immersive format that communicates your message quickly, especially using the Playable platform, making it a powerful tool for digital marketers. Playable simplifies this process of uploading and deploying video in email campaigns through a Copy-and-paste method for HTML code, making it easy to integrate within any email marketing or customer engagement platform.
Supported Video Formats and Email Clients
The MP4 format is the most widely supported format for video in email. Other formats, like WebM or OGG, have limited support and may require fallback solutions. Email clients such as Apple Mail, iOS Mail, and Outlook for Mac can play video directly within the inbox. Gmail, Outlook desktop or Windows, and some web-based clients may only display a static image or animated gif as fallback.
Choosing the right supported video format ensures that your email looks professional and functions well across all devices and email clients. Playable’s video technology automatically optimizes videos across all devices and customer environments. It helps to add fallback strategies like static images or GIF previews, which guarantees recipients still receive the video message, even if the video playback isn’t supported in some email clients.
Device Considerations for Video Email
The device your audience uses, whether it be desktop, tablet, or a mobile device, affects how video is displayed and played. Mobile devices often play videos without sound to save bandwidth, while desktop and tablet devices may support higher-quality resolutions but vary depending on the email platform. Understanding device behavior is essential for optimizing video content to ensure a smooth experience. However, Playable automatically optimizes video content across every device, without needing to do extra work or testing, saving time and effort for marketers.
The video size and quality can also impact the video performance. Large, high-resolution videos may increase loading times, especially on mobile networks or low-service areas. Playable helps to optimize file sizes and maintain quality to ensure faster delivery, reducing the likelihood of playback issues.
Common Video Email Challenges
Sound and Autoplay
The main issue that marketers face with video email is silent or muted videos. Most email clients such as Gmail, Outlook, and Yahoo! Mail disable audio to improve user experience, especially within mobile devices. The email clients that support video audio in emails are Apple Mail, Outlook for Mac, and Samsung Mail. To address this audio issue, consider adding captions, text overlays, buttons, and Calls-to-Actions, so your video messaging is understood even without sound.
Outlook Compatibility
Outlook is notorious for limited video support. The Outlook desktop version often cannot play video inline which requires marketers to use fallback static images or GIFs. However, knowing these limitations can allow you to plan video email campaigns that can better engage your audience, regardless of client or limitations.
Video vs GIF
Although video provides much higher-quality resolution and visual experience compared to GIFs, they can serve as a lightweight alternative to video display animations without needing full playback. As GIFs don’t include audio and have a lower visual fidelity, they are widely supported in email clients such as Gmail, Outlook, and Yahoo! Mail, and are ideal for teasers or short animations. It is recommended to use GIFs for previews and video for full storytelling.
Integrating Video With Email Platforms
Playable integrates with popular email service providers (ESPs) such as Braze, Benchmark Email, Klaviyo, and Mailchimp. These integrations allow email marketers to quickly embed video, track engagement, and analyze performance metrics all in the Playable platform. Using an email marketing platform with native video support can improve deliverability, simplify campaign creation and management, and ensures a smoother customer experience.
Best Practices for Video Email Campaigns
Video is a powerful tool to drive engagement and conversions in email, but its success relies on thoughtful execution. As email clients can vary in their level of video support, the following provides the best practice for video email campaigns, including:
Integrate instant-play videos: Playable plays video automatically and instantly when the email is opened within 98% of email clients, including Apple Mail, Gmail, Yahoo! Mail, and most versions of Outlook. However, recipients using legacy Microsoft Outlook on Windows will see a static image instead.
Include GIF previews: Not all emails clients supported embed video, so it’s important to provide an engaging fallback like lightweight animations.
Optimize for mobile devices: Keep video formats as MP4, file sizes small, and design responsively to ensure a smooth experience and playback.
Test across devices and clients: Playable makes it easy to test how your video emails render across major email clients, devices and user environments, ensuring consistent playback and reliable fallback behaviour.
Define video goals: Decide whether the video is meant to drive clicks, increase views, maximise conversions or showcase a product. With Playable’s new AI video capabilities, it allows marketers to determine video goals and content faster.
Testing Video Email Campaigns
Testing is critical for understanding how your video performs across devices and email clients. It is recommended to use internal testing and specialized platforms to evaluate playback, resolution, and data usage. This helps identify potential issues, optimize delivery, and improve engagement before sending campaigns to a broader audience. However, Playable does remove this friction by being able to test and optimize videos within its platform.
Data Usage and Performance
Video emails are relatively efficient in data usage when optimized, but high-resolution or long videos can strain networks. Making sure to balance video quality with file size is needed to ensure smooth playback on both desktop and mobile devices. Proper optimization reduces load times, improves recipient experience, and maximizes engagement.
The Future of Video in Email
As video in email continues to evolve, more email clients and marketing platforms are supporting video media and advanced playback features. Digital and email marketers who understand device and client limitations, optimize video content and design, and test campaigns will see higher engagement and ROI. Integrating video in email is a strategic tool for storytelling, connection, and conversion. Playable delivers the highest quality video formats, including MP4 and HEVC, to each email recipient depending on their device, email client and networking conditions, so that every recipient enjoys the highest possible playback quality.
