Called to try and set up an account. The Lady on the phone said that because we only had 15,000 subscribers that no one was willing to give me any more details about the service and that they would send me an email. After being berated by this lady I asked to speak to the manager she said no laughed down the phone and hung up. I was a little surprised as I only wanted a quick overview of the platform. Hubspot, Marketo, Drip and Active Campaign have all been very professional when discussing their service, I don't know why Campaign Monitor isn't.
