List of mailings with public view
List of mailings are not directly available for anonymous or authentic user with limited permission. However you can have it available in one of the 2 ways


Using Public Mailing Archive extension(You will need to tweak code to work as per your requirements for example this extension list Mailings using Mailing subject, change the variable in tpl file to use Mailing name)
Create copy of Mailing Summary report and give access to Anonymous user. (I would create an extension that will add a special permission and use hook to alter the link of Mailing Name to use mailing view link).
