yMkt: how to send email without external provider

Hi experts,

I'd need to define email campaign and to send mail to the target group members without an external email provider service.

I read the installation guide where I found the details for "Setting up Amazon Email Service Provider" and, alternatively,  "SAP Mobile Service for Email" configuration.

Do you know if it's possible to send out mails without these external providers (with the well known SCOT) and how to configure it?

Waiting for your kind feedback.

Kind Regards.

Daniela
