Shopify Messaging

Just tested Shopify Email having been a regular Mailchimp user for the last few years. They don't really compare. Shopify email user interface is clunky and the send time (we have 2,500 subscribers) is really slow due to the batch sending. Also... the Reports interface is very very slow to update, it's not giving me statistics in real-time.
Not sure if we are going to keep using it.... I like that the cost is lower than Mailchimp (thank you Shopify) but please, please keep developing this functionality so that it works smoothly, quickly, intelligently. Right now it's not very intuitive and I am not convinced I'm going to stick with it.
