Their support team is really helpful. They're always there for you when needed! We use their service to help us manage our email campaigns through MailChimp (among many others) so that we don't have too much work managing it ourselves via other tools like Constant Contact or AWeber etc.. The platform works well across different emails & tracking KPIs makes things easier than ever before!! Thanks Rollie Coasters. Nothing specific but all in general they are great people who care about your business/project success :) I highly recommend them if u need some assistance getting set up quickly without having technical knowledge of how everything functions :). The best part of roller coaster is its simplicity to use for our customers who are not very tech savvy or computer literate people like me! I can't think about anything that i dislike in this product at all so far because it has been working perfectly fine since we started using it few months back. It's just perfect software which helps us save time by automating repetitive tasks such as sending email reminders etc.,.
