Thanks but your self-hosted solution costs $600 to $900 a month to license it.

I was hoping to find a 1 time purchase solution that meets those requirements. Sorry for not being more clear in my description.

We also have a one-time purchase option. Although it starts at $6,000. We serve a lot of larger businesses with higher volumes, like Six Flags or Fry's Electronics, and email service providers.

Yep, I saw that. I didn't mean for my comment to come out rude either. Just catering to a different audience. Thanks.
