I love that it's easy to use, is completely customizable (you can create your own templates), has great support team behind this product as well! It would be nice if you could have more than one recipient in each "to" field but overall very satisfied with what they offer so far!! If there was an option of having multiple recipients per template then we wouldn't need another tool like MailChimp or Constant Contact because our customers are already using those tools anyway which makes life easier when creating their personalized messages.
