You don't get it. Stuff like this does not discourage designers. It is what gets them jobs and keeps them employed. I've worked with marketing departments where it was a designer's primary job to make things look good on email campaigns.

I had a recent request from a product owner to style the subject line... I said we can't do that and that I don't want to live in a world where senders can change the font or size of the subject in an email.... Can you imagine the crap we would have from spam in that case?!

You can always pack it with emojis and unicode characters... that's what all the spammers seem to do at least.

ie don't any mua let you use UTF8?

𝔻𝕠𝕖𝕤 𝕥𝕙𝕚𝕤 𝕨𝕠𝕣𝕜?

The first one does not work great in a terminal. The words are readable but I don't get the full experience. The second one, pretty good.

Seems like your terminal doesn't support the last line. I will repeat all three lines in tunarly fashion.

Line 1:

" You have wøn a prize! "

Unincluded line; my sister got bitten by a prize once. Or a terminal. Onto line twø: two:

Line two: (2:)

" ie don't any mua let you use UTF8? "

And three:

" Does this work? "

All the lines for all the good people. The " signs " are a delimiter for each line. They're, or should be pretty verbatim, minus the unrenderability.

Have fun.

Ah, I referred to the third line, "𝔻𝕠𝕖𝕤 𝕥𝕙𝕚𝕤 𝕨𝕠𝕣𝕜? ", as the "second one" in my message, without mention for line 2, which renders correctly, fortunately. But thanks for the heads up.

Firefox on mobile mangle that pretty bad on - at least the vertical space :/

Firefox Mobile renders it well for me, are you sure that the comment is not rendered as it should be (with garbage from line 1 overflowing over line 2)?

I thought the owerflow should be "well behaved" (in terms of correct layout/vertical space)?

Is it correct to have "overhang" into the line below? Isn't it a case of incorrect layout?

I think it is correct, as surprising as it can be. See this famous stack overflow answer for instance: https://stackoverflow.com/a/1732454

Indeed, if it's possible, marketing is going to ask for it. And unless you have dedicated developers who specialize in email campaigns, ready to brave the nightmare that is fighting against email client formatting, the only sane and cost-effective solution to implement any kind of layout in an email is simply stacking inline images with text included.

Microsoft's history has shown time after time that both internal conflict and external enterprise clients' requests lead to random developers adding bits and pieces of non-standard features. This applies not only to Outlook but their other products (incl. Windows). It is goddam' Wild West out there and they clearly give no crap about how the standards outside of their universe evolve.

Sorry Microsoft, but the PC world is not Windows-only anymore.

By the same logic you could say that internet explorer was doing good things

No, the logic is: I want styled content on the Web and plain text in my emails.

It's not a new problem and MIME was intended to give people the choice. Not everyone likes plain text emails or terminal email clients. The solution may be forcing email senders to include text/plain as well as text/html.

For that very reason you have MIME type setting
