Ohdita review for Omnisend Email Marketing & SMS

BE AWARE - they don't disclose this before installing the app. "Kindly note that as of now, the Omnisend logo can only be removed from your Forms and Campaigns if you are subscribed to one of our paid plans, either the Standard or Pro plan." I could maybe go with Omnisend logos showing up on the bottom of an email, but not on a sign-up popup! That makes the free plan pretty much useless. Also, they failed with the first try of communication. After a long wait, I received a quick reply that didn't address all my questions, and then they just stopped responding altogether. I spent an entire day trying to figure out how this app works, but at least I discovered these issues early, giving me the chance to switch to a different app. It makes me wonder, how can you build a business with this kind of customer treatment?
