I have seen this in e-mail html code. Does anyone know what the "3D" is for?

It is a bug(mistake)
And you can see it in your email just because it's a bug

Actually I found out its part of an encoding process pretty much just used for email. I believe it's called quoteable print. It has to do with SMPT only sending 7 of 8 bits data where the 8th bit is a check. Certain characters over 128 can get muddled as well as other characters like = and space.

3D is hex for equal and the "=" is the key the encoding sees just the "%" in URL encoding.

Amazon uses but many others do not.

I can send more detailed and accurate info if you'd like.

This is also used by Gmail.
If you go to 'Hide Options' and click 'show original' for any email with links in it.
And you'll usually see,
href=3D"http://www......
used.
