I sent out a newsletter today only to find out there were a couple of links that didn't work. I was able to edit the newsletter.
Now, if I go to the online version, my corrections seem to be effective.
If I go back to the e-mail that I originally sent, the broken links are still there, changes are not taken into account.
So is too late or is there a way to edit a newsletter after it was sent so that subscribers will open an updated version of it at their end?
