Fully supports overflow-wrap (4): Outlook for Mac, Samsung Mail, Proton Mail, Superhuman.

Production guidance for overflow-wrap

overflow-wrap is a CSS property. Across the email client matrix, 4 of 15 tracked clients support it fully, 2 only partially, and 12 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 overflow-wrap 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.
