I had a very disappointing experience with SendPulse. I applied to use their SMTP service for two legitimate purposes: first, to connect with my existing clients via Apollo.io (which was never actually used due to Apollo's own limitations), and second, to send OTP verification emails for new users registering on my cybersecurity SaaS platform.Without any actual sending activity or violations, my account was suddenly labeled as “exhibiting characteristics of a spam account,” with no real explanation or proof. When I asked for clarification, their response was generic and evasive, refusing to provide any specific reasoning. Instead of handling the situation professionally, they simply shut the door with canned messages.If you're a legitimate business looking for serious email infrastructure, I recommend looking elsewhere. Transparency and respect for clients should come before vague assumptions.
