Hey Wesley, thanks for the email and informing us about this.
Our security system detected other emails that were being linked to this account. We’ve been experiencing increasing spam usage of our free credits on the trial, so we recently implemented some robust security measures against this as we grow!
Since you previously has a paid subscription under that email, I went ahead and unblocked it for you. It's best to only use that account moving forward to prevent this again.
Let me know if you have additional questions!
