Production guidance for <video>
<video> is a HTML element. Across the email client matrix, 2 of 15 tracked clients support it fully, 2 only partially, and 11 not at all. The clients most likely to require a workaround for this feature are Gmail, Gmail Android, Gmail iOS. Each of them needs a tailored fallback — see the per-client examples above for the specific code fix Emailens recommends.
When in doubt, ship a baseline that renders without <video> and treat it as progressive enhancement on clients where support is verified. Emailens automatically detects cross-client divergence on this feature when you preview an email, so you can see exactly which template paths break before a campaign goes out.
