The support is AMAZING
I'm leaving this review after 1 and a half years of using this platform and all I can say is that Mystrika is a good replacement for Instantly
It might not have the same UX / UI (they made improvements this year) but it gets the job done, and email marketing being a new thing for me, I quickly ran into multiple problems because I didn't know how to use the platform
However, the support is amazing, I get almost instant responses from the founder and he or the support team are always checking the Facebook Group to fix bugs, or to address any question someone might have (me included) and there are tutorials on youtube how to set up everything
Overall I'm very happy with Mystrika and if you are thinking about email marketing this is a platform to use!
