Omnisend Email Marketing & SMS

Great app, super easy to use, great customer service as well (thank you Nikola and Marija)! I've only used it for newsletters and abandoned carts for now. (And the abandoned carts-flow is the reason why I only give four stars, because for the few days I used it, several customers got an abandoned cart email even though they completed their purchase... But they say they are working on the issue.)
