To create a new message template in Invoxy go to Manage > Templates > Message Templates and click Add Message Template, or to edit an existing template click Edit.
From there you can change the text and Placeholders contained in the Message body and Subject Line.
Placeholders in Message templates are replaced with the corresponding information from elsewhere in Invoxy when the messages are sent, for example you might like to use the 'Invoice Number' placeholder in your Client Invoice template - when the email is sent, the placeholder will be replaced the the Invoice Number of the invoice attached to the email.
NB: The Placeholders available for a template will change according to their type eg. Client Invoice vs Request Approval.
