How do I link an archive of past newsletters on my website?

I would like to create a Folder/Library link on my website for the Newsletter Letter emails sent.  I thought the best way is using the https://contract.cc/ code.  I know how to do this individually, but the library needs all of 2022 to date and moving forward.  

I have created a folder, but the url for the folder only takes me to the full campaign list not to the folder.
