This one was reported on the Antiphishing working group as an active Phish, but it's really something else. Not that you'd actually want this to happen to you.
This is an email from a 'Vonage affiliate' named ankle4.com. They seem to be offering VoIP long distance service, and I'm sure they are - but that's not their main line of business. The code behind this email is FULL of 'web bugs' - each image reports that your email address has opened and read the email, even if it's just in a preview frame. Then, if you click on the link, it reports that not only did you read the email, but you RESPONDED to it.
Ankle4.com is probably getting paid to track and collect email addresses for future marketing schemes. IOW, they're SPAM enablers. Anklebiters, more like.
To avoid this, use
Mozilla Thunderbird. It won't display remote images that may contain webbugs until you click a button to allow the images.
