In the email related SendTo outputs setups, you will probably have noticed (in the SendTo (edit) dialog), the email section at the bottom half of the dialog, showing the selections for:-
Subject:
Text message:
HTML message:
CC email address:
BCC email address:

The subject will be set as 'Document(s) Delivery', there is currently only one choice.
The Text message will be set as 'Please see attached document(s) + Signiture'

If you change the Text message setting to the one without the signiture, I will explain how you can change the standard text for this one and the Subject...

Goto the Advanced part of the Control Centre and goto the 'Reports & Tasks' page.
Scroll down the list until you see the Group entries for:-
Email Subject
Email Text Message -- Please see attached document(s)

Double-click the 'Email Subject' entry...
The report editor window will appear.
Double click - line 100, the report item editor window appears.
You can edit the subject text (only one line, as its the email subject) and click OK
Click OK on the Report Editor window to get back to the main reports list.

Double-click the 'Email Text Message' entry (the one without the signiture, the one with the signiture entry is too technical as it contains database script to generate your labs name and address details automatically from the database).
Double click line 100.
Here you can enter your desired text message, it may contain as many sentences and blank lines as you like. You can include you lab name and details at the end, if you wish.

If you need assistance, let us know.

Note: the above settings and setup, mostly control the automated emails generated from Transactor. Another way of inputting your desired email Subject and meesage text is when you are sending individual reports via the REPORT - PREVIEW WINDOW. On the toolbar of previewed report, the third button from the left is an email button, click this and you are presented with an emailing window with the report automatically attached as a pdf file. You can set your own subject and text before clicking SEND.

The above features will be made easier and more flexible in future version updates.
