I would like to get your contact information, I have sent you emails more than once asking my questions, but I don't seem to get any answers. This is probably the best joke I've heard this year, I've emailed you guys at least 2 times and it's taken 1-2 days for you to get back to me each time.

This is super easy to use, has great templates and so many options. We send weekly newsletters, and also use the abandoned cart function. Love it.
