ODS PACKAGE publish email does not send emails

Question

SAS EG / SAS 9.4

I am currently using ODS package to zip a few files and then send them over to recipients using filename email. I recently came through the ODS user guide (see EMAIL PROPERTIES) that says we can publish the archive to email addresses.

I am using the below snippet - (I've used libname and filename statements)

ods package (proem) open nopf;
ods package (proem) add file=a1;
ods package (proem) add file=a2;
ods package (proem) add file=a3;
ods package (proem) add file=a4;
ods package (proem) add file=a5;
ods package (proem) publish email   
    addresses ("[email protected]")
    properties (archive_name="Products2Email.zip" archive_path="%sysfunc(pathname(crap))");
ods package (proem) close;

The above code creates the zip file in the designated path, but doesn't deliver it to the email address provided. The zip file, that gets created, is a little less than 1 MB in size, and I am able to send it via a data step using filename email statement.

Is there something that needs to be changed or checked, or is it that I am wrong in interpreting the ODS user guide?
