I signed up for the free service and have sent out 500 emails. It went good; 35% open rate, and nearly no unsubscribers (below 1%). When I got into a paid plan, an employee called Alexander basically called me a liar that our subscribers have not subscribed to our service. I have paid 70 euros for the service, and now I cannot send anything. SendPulse is clearly a scam and seems logical that they have such a bad rating. I only wished that I had checked reviews before signing up.
