Users have the ability to add different types of mailings, acknowledgements, and receipt processes. In most of these processes we find that constituents without contact information such as addresses, emails, etc, are not pulled into the processes results. Users are finding that this is not the case in receipt processes no matter what output format being used in the process and that constituents without addresses or emails are being included in the results. This causes results to be created that can't be sent which is confusing to users due to how other similiar processes function.
This is a result of the default Address Processing options being used not being configured properly. To resolve we must update the address processing option and set the 'If address is not found:' option to 'Remove from Results'
