Error Handling

Dynamic content does have some risk. If the data is not passed as expected, data is missing or a parameter name is specified incorrectly and not caught in the staging process, undesirable results can occur.

To minimize this risk Connect provides two ways to catch these conditions:

Use the MS.InvalidContentMsgs System Parameter to specify a string, which, if found in the body of the message, prevents the message from being sent.
Have the content generator return the "204 Content Not Found" response. Please note that it is not a string but an HTTP response code returned by the web server.

We recommend that you use these measures only as a precaution to catch errors, rather than a method to determine Mail Recipients.
