You can create a different template for each table that uses the email client. Email client templates allows to use email scripts and variable substitution to complete the fields available on the template.
For example: current.caller_id.email + ; + current.assigned_to.email
Note: This code does not work with more than one email.
On the result email sent, the recipients look like recipient1;recipient2; which is incorrect instead of recipient1,recipient2; which is correct.
The error string shows Error SMTPSender: no recipients, email send ignored
|Note: Email Scripts are not able to modify the email object as it does not exist at the time the Email client executes. This mean that functions like email.addAddress, cc, xxxx do not work on email client scripts.|
