The support team is very responsive, helpful and kind - they really do go above and beyond to help you with any issue or query that arises! I have used them for many years now (since 2013) and always been impressed by their service level and professionalism.
There's nothing we dislike about them at this time. They're great to work with; highly recommended! We use MailChimp as our email marketing platform but it can be difficult to find out what works best in your situation so having someone who has experience in these areas of eCommerce will come in handy when making decisions.
