What fonts can I use in HTML emails, other than Arial, Helvetica, Verdana and Times New Roman? Is there a list? Like, if I open my MS Word, I’ll get about 12 fonts (like Georgia, Geneva, and such). Is that the list, pretty much? I specify in my SPAN tags, in my emails “Arial, Helvetica, Verdana, sans-serif”. I know every browser/computer may display something different, within the parameters I defined. But even if there is a list of 12 fonts that I can use in HTML emails, I’d like to know what they are. I’ve seen people use common fonts in HTML emails, like, Trebuchet (I probably did not spell that right), Tahoma, etc. I often receive HTML emails that use fonts other than Arial. They look good. What fonts are they using?
I ask this because I come from a Mac and print world, where there was an abundance of fonts. Then I started working on HTML email, and I feel comfortable coding them, etc. But I can’t look at Arial anymore. My eyes hurt. I need to know what other fonts can I use. I have thousands of fonts on my Mac, but I probably can use only few. What are they?
Thank you to everyone for taking time to respond.

since you get so many html emails, i’m sure upon receiving them you can use dev feats of the browser of your choice to see what fonts the sender used 
it’s not about what fonts you have, it’s about the common fonts shared by all web users on their OSs: Win, *nix, Mac etc.
that’s why you specify more than one font: “Arial, Helvetica, Verdana, sans-serif”. if the first is not found, the second one is considered. if the second one is not found, the third one is considered. and so on until a sans-serif font remains as the last option.
this line: “Arial, Helvetica, Verdana, sans-serif” is about “browser safe fonts”. sitepoint users also [URL=“http://www.sitepoint.com/forums/showthread.php?t=645672”]discussed this issues.
