I work as an email marketer for an online store and have been using Unisender for a couple of years now. I'm satisfied with the deliverability, segmentation, and analytics. I conduct A/B tests, which helps improve results. We tried setting up a chatbot, but there are still opportunities for development in that area. I haven't had any issues with Unisender, but I do resolve some questions through support, as it's faster. I've used other platforms (SendPlus, Mindbox), but I liked this one the most.
