Emojis in Email subject Line - Outlook Rendering

HI All,

I was able to render emoji's in the email using unicode or direct copy paste. But when checking on rendering for different clients. Most of the clients support and I can see the emoji's but few like outlook on specific versions were only rendering gray scale versions of emoji's.

Is there a way to render them with colors or since that is out of AJO scope and outlook is the one finally deciding it, It will not render.

AI response -
Outlook on Windows (Classic): Emojis in subject lines are rendered in grayscale. This is a known limitation. Even if you insert a colorful emoji, it will appear black-and-white in the subject line on Windows

Thanks

@rakeshk1 It’s a limitation of how Outlook renders, not AJO.

here is response from AI on the emoji rendering within outlook:

  • Outlook for Windows (Classic versions, especially 2016/2019/Office 365 desktop with Word-based rendering):
    Emojis in subject lines and sometimes in the email body render only in grayscale. That’s because Outlook relies on its own rendering engine (Word + Segoe UI Symbol/Segoe UI Emoji fonts), which don’t support colored emoji glyphs in those contexts.

  • Modern Outlook (Outlook on the Web, New Outlook for Windows, Outlook for Mac, and Mobile apps):
    These clients do use system-level emoji rendering, so you’ll get the full color emojis.
