How to track custom mails in sourcing

Hi Experts,

As per our requirement we have implemented the explicitly called script to send mails to the MA/SA collaborators on agreement expire date.

We have not used SAP provided custom mail template for this, we have used send mail function in script.

Mails are going out without an issue, but for our internal tracking purpose we are printing the log message saying that "custom mail sent to"+username.

But it is so difficult for us to check the log messages every day because every time we need to ask our basis team for logs and need lot of approvals for that.

So we are looking for an alternative to track the custom mail sent from explicitly called script.

Please help us, if anyone have an idea on this.

Regards,

Lava
