Hello @HollyJ09 ,
A subdirectory type URL will work like any other normal URL when inserted as a link in your emails, landing pages, etc. For example, I can link to our Community's homepage https://community.constantcontact.com/ or the Help subdirectory of https://community.constantcontact.com/t5/Get-Help/bd-p/advanced_support .
Similarly subdomains (e.g. https://www.constantcontact.com/ versus https://community.constantcontact.com/) will also work in this regard.
