Thank you for your post.
Are you using the "Send Campaign" script? If so, are any of the dialog messages appearing? If so, which ones?
There are many steps in the "Send Campaign" script, so I'll need to know at point the script is failing.
I Am having issues with this also. the first 10 messages or so generate fine. the remainder generate with no email address in the "to" field. How can we get this to work? Is there an update to the sendmail script.
Looking at the "Send EMail" script, there are some error messages built in. First, if the email address field is empty, you should get an error message that there is no email address for this record. If it isn't empty, then it tries to send the email using a calculation field that concatenates the first name, last name and the email address. If this fails, you should get an dialog box saying there an error in addressing the email.
It sounds like you are getting the error for the former. Make sure Contacts::Email field is not empty for those records.
