I have a small date change I need to make to a few newsletters I've already sent and linked to my web site. Can I edit the archived versions so I can retain the existing archive URL in my web site? When I select Edit on an already sent newsletter, it seems to be directing me to make a copy, make the change, re-save under a different name, re-send (even if just to myself) to generate a new URL, and replace the URL in my web site.
At this time sent emails are only editable by making a copy. With that said, you are correct, making a copy of your email will create a brand new campaign and cause you to take the following steps you have described. I apologize for any inconvenience this may cause. Being able to edit a sent email without copying it first is a great feature request we have tracked in your account.
