Omnisend Email Marketing & SMS

Really good app, I have been using it for one year and I can definitely say it is way better than Mailchimp. Many options to choose from and very good, detailed insights.
The only thing it could be improved is the customer service though. At times you have to wait long before an agent takes on the conversation. I had to also explain my issue several times when agents switched as their shift was over and it is pretty frustrating when you need your problem to be solved as quickly as possible. Nevertheless, I recommend this app.
