Software license plus installation on your server. Pay once, own it forever. Optional annual service package from $3K/yr.

Not included: the server and email delivery.
Octeth runs on a server you provide, which costs a fraction of the license, and sends through your own SMTP server or a third-party provider such as Amazon SES, billed by the provider per email.
If you run your own mail server, the license is the only software cost.
