Hello,
when creating a mail model, data from project are not available (only nameproject).
But, because everything is linked to a project, be able to add data from project (such as status, manager, or custom fields) will be great.
For example, we use mail model to create automatic mail for an expense to budget supervisor (supervision is made form another organization) and need to specify some data from project (such as budget codification, that is dependant to project but not include in budget for example).
For example, prohect are linked to Code eOTP add whe need this code to speak with budget's supervisor. So, be able to insert fields as project.codeeOTP will help to construct correct mail, otherwise we have to create all message from copy-paste from notepad

!
Offer access to every linked object for a mail model will be complex, but offering access to project's data, wich is the center object of ProjeQtOr will be easier and a well plus-value.
Expect to be clear
Regards,
