The worst ESP i have been workin with. Poor support, poor deliverability. Bulit in integrations not workin with anything on getresponsemax support. Dedicated account manager does not respond to emails or responding after few days :). Segmentations and reports are really poor. Not reccomending that system to anyone, maybe for freelancers, small ecommerce but for sure not for midlle and bigger companies. Rrccomendations exists but no conversions from them. Editor is awfull - create bugs in code with two column layout.
