Also, my standard “signature”, seen below, is not shown, in the “test” messages.
The Personalized Emailer will not place the default GroupWise signature into the mass emailer messages. 3rd party developer unable access the default GroupWise signature using Object API or Token API. The SOAP API (GroupWise 7 and later) seems to provide option to access the default signature but it need further investigation.
In the mean time, you need to add the signature in the master email template. In a nutshell, only the message contents in the master email template will be sent to the recipients.
