Go to your "Sent" folder of Gmail, and find the message you think did not make it to the list. Click on that message, and you should see the 3 vertical dots at the right margin. Click those 3 dots and select "Download message". In the file that is downloaded you will see "Message-ID", "date", and other headers -- this is what Ian asks for.
