Making the webversion link of an ACS Email permanent

I often have to share ACS emails with people who do not have access to ACS, so I typically send a link to the web version of the email to these people. However, I noticed that these links break after a couple of months and I can no longer access the link. Has anyone found a way to make these links permanent?

Alternatively, if there is a better way to export the email such that the dynamic variables are filled, that might work as well.

Thanks!
