I have been using Spinnakr since it was in beta, and I can say without hesitation that their platform has made my life easier. The customer service team is great, and they are always willing to help. Their support is fast and reliable. They also have some really cool features like auto-responder emails, which makes managing my email campaigns easy. Sometimes there can be lag times when sending an email through their system, but this is something that could probably be fixed with more resources.
