If you're finding that you're sending tests from the platform and you're never receiving them in your inbox, it's highly likely that your messages are being caught by your anti-spam solution.
It's possible that if you're using your business domain in any way for Spotler, emails from the platform to your work email address are getting blocked by your corporate email filtering solution. The email is coming from somewhere that the business doesn't recognise as being associated with your company.
