I like how easy it is to use, all of my emails are in one place which makes them much easier than having multiple accounts or folders! It's not very user friendly at this time unless you have an IT person that knows what they're doing. The customer service has been slow but when someone does get back to me there isn't always any information given about why their response was delayed so sometimes I'm left wondering if something went wrong. If your looking into getting email addresses from people who don't already subscribe through other means such as Facebook then go ahead give it try because we've had great success using gvd since our campaign started last year. We were able to reach out to thousands of new voters without spending hundreds of dollars each month just by reaching out via social media platforms.
