Omnisend Email Marketing & SMS

I recently switched to Omnisend - this is a powerful tool and the support team is extremely helpful (even when starting with a free account). I had some more advanced segmentation to create and the support agent Sarah stayed with me offering suggestions and checking my work to ensure it was set up right. This tool can do far more than most of the CMS/Email Marketing apps on Shopify. If they keep up this level of service and great functionality, they'll own the market in no time!
