Tweaking html emails so they display correctly in gmail

The following piece of code renders fine in almost every email client imaginable except for gmail, which shows the Testimonial Match Alert in black instead of white text. Does anyone know any way to force the color of text other than what I am doing below?

Thank you!

<tr>
<td align=“center” bgcolor=“#337711” style=“font-size: 25px; line-height: 25px; font-family: "Droid Sans", Arial, Helvetica, sans-serif; color: #ffffff;”>Testimonial Match Alert
</td>
</tr>

Hm, each email client has its quirks, but I would expect that to work. Perhaps at least try changing

"Droid Sans"

to

‘Droid Sans’

If that doesn’t work, you could try wrapping a span around the text and applying the color on that.
