We are using "SendEmailNotification" OOTB activity to send mail and setting the custom subject, body and To values as per our requirement. But, the email is not delivering when the email subject is more than 84/85 characters. It will be helpfull for me if any one provides the solution.
1. We are using PEGA PRPC 7.1.9. As per our project requirement we may need to set the Subject upto 140 characters dynamically.
2. No errors/exceptions found in tracer and log as well and more over outbound email connectivity also fine.
Just to give a hint on debugging this further; if there are no errors in the logs and tracer on PRPC side, can you check in the sent box of the outbound email ? If you can see your mails there, then try checking the junk mails of your To email ?
