Matching process -email notification.

Currently we are using Matching process and not using the email notification process.

We would like to use the delivered process to send email notification.

How do I setup the email notification and email template for Match exceptions.

I have a requirement to send email notifications for each rule.

Example  RULE_E100- Extended Price Tolerance for this rule, email should go to requester as soon as the exception occurs.

After2 days need to send an follow-up email.

After 5 days escalation email.

Email should include voucher id, invoice id, PO id, receipt id, invoice amount and invoice date

and some other body with custom text.
