A post shared in r/Emailmarketing pointed readers to an ActionRocket experiment on making video work in email with custom code. It is a useful provocation: email designers should keep testing the boundaries of the inbox rather than assuming every campaign must be static.
But for creators, founders, and small businesses, the enduring lesson is not “learn the right <video> snippet.” It is design a video moment that still works when the inbox declines to play along.
That distinction matters because email remains a fragmented rendering environment. What works in a browser may be removed, ignored, or replaced inside an email client. Mailchimp’s current guidance is blunt: most clients cannot display embedded video and may strip the code; its recommended implementation is a clickable thumbnail that opens the hosted video in a browser. (mailchimp.com) Mailchimp likewise lists embedded video among the HTML elements marketers should avoid in email, alongside JavaScript, iframes, and embedded audio. (mailchimp.com)
The inbox should sell the click
For most newsletters, email does not need to be the place where a subscriber watches the full video. It needs to make the next action obvious and appealing.
That means the dependable pattern is simple:
- Host the full video on a fast destination — a landing page, product page, YouTube, Vimeo, or your course/community platform.
- Use a strong thumbnail in the email — ideally a real frame from the clip, not generic stock art.
- Add a visible play affordance — a play button helps recipients immediately understand that the image leads to video.
- Write supporting copy that supplies the reason to watch — what will they learn, see, decide, or get done?
- Link both the image and a text CTA — never make the image the only route to the video.
This approach is not a compromise. It gives you more control over the viewing experience, lets the destination page carry a fuller CTA, and works for subscribers reading in Gmail, Outlook, Apple Mail, or less predictable corporate inboxes. Animoto’s updated guide reaches the same practical conclusion: direct embedding is limited to certain platforms, while a linked thumbnail or GIF is the safest broad-reach option. (animoto.com)
When an animated preview earns its place
A short GIF can be a useful middle ground. Instead of pretending an entire video will play in the inbox, show a two- to five-second visual proof point: a product changing states, a before-and-after, a creator’s face reacting to an announcement, or the first step in a tutorial.
Use motion to answer one question: why should I click?
For example, a software founder could show a cursor turning a messy spreadsheet into a clean dashboard. A newsletter writer could preview a chart from a deep-dive issue. A course creator could show the finished outcome before inviting readers to see the process.
Still, build the first GIF frame as if it were the only frame recipients will see. Some email clients do not support animated GIFs, so Mailchimp recommends testing campaigns thoroughly before a full send. (mailchimp.com) Make that first frame legible, branded, and complete with a play icon or clear CTA.
Reserve true embedded video for controlled experiments
The original ActionRocket post is valuable because advanced email production benefits from experimentation. If you have a technically sophisticated team, a well-understood audience, and a clear reason to test inline playback, HTML5 video with a carefully designed fallback can be worth exploring.
But that is a segmented experiment—not the default architecture for a launch email. Start by checking which clients dominate your opens, send a test version to a small cohort, and judge success on downstream behavior: qualified clicks, watch time, registrations, purchases, or replies. An impressive in-inbox demo that reduces reach or obscures the CTA is not a win.
Measure the video journey, not just the email click
A video thumbnail can produce curiosity clicks that do not become meaningful views. Track the chain:
- email delivered;
- thumbnail or CTA clicked;
- landing page loaded;
- video started and watched;
- desired next action completed.
Add tagged links so email traffic is distinguishable from social or search traffic. If possible, compare a video-preview version against a static-image version with the same offer and CTA. The result will tell you whether motion is creating attention—or merely decoration.
The practical takeaway from the old “video in email” challenge is surprisingly current: the best video email is resilient. It gives compatible inboxes a richer experience, gives everyone else a clear visual invitation, and ensures every subscriber can reach the content that matters. In other words, code can enhance the campaign, but the fallback is the strategy.
