float

Client-by-client behaviour for float

Fully supports float (10): Gmail, Outlook 365, Outlook iOS, Outlook Android, Apple Mail, Apple Mail iOS, Samsung Mail, Thunderbird, HEY Mail, Superhuman.

Partial support (3): Gmail Android, Gmail iOS, Yahoo Mail. Expect rendering quirks unique to each engine — partial support typically means a subset of values, an ignored shorthand, or sanitizer-specific rewrites.

No support (2): Outlook (New), Outlook Classic. Plan fallbacks for these clients before relying on float in production sends.

Production guidance for float

float is a CSS property. Across the email client matrix, 10 of 15 tracked clients support it fully, 3 only partially, and 2 not at all. The clients most likely to require a workaround for this feature are Outlook Classic. 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 float 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.
