Not enough font types and sizes
There are not enough fonts on Yahoo Mail; its way too limiting. I find it boring to type and send an email from Yahoo; I feel that when typing an mail it's very transactional and not personal to me or from me.
e.g. comic sans as a font type has been around for ages; why can't it be available.

I would like to see a list of fonts I could choose from to write email messages. For example, "Georgia" or "Cursive" or whatever, rather than the generic selections that are present now.
