in reply to Email Subject with Icon

I'm fairly certain the subject line is text only. If you're seeing images in email subject lines, chances are it's just a unicode character.


Update: and there's probably some email client somewhere that will turn emoji codes to the proper unicode representation.

    Thanks for the response.

    Probably I should have made myself more clear. I was thinking in the lines of favicon which you see in the browser infront of the url.

      SMTP, the standard email protocol, does not specify support for anything like a "favicon". While there may be some email clients which add it as an extension, they are exceptions to the rule. Even if you were to arrange for your image to appear in the subject line on one mail client, the vast majority will not display it at all (indeed, many aren't even capable of displaying an image - text-only mail readers are still around) and, even among those which display it, most would probably display it elsewhere.
