I thought so.. ??
I’ll just describe the way the receiver should be able to act:
I receive the newsletter in my email-programm. Possibly I click the link “view this email in browser” because it looks better. In the newsletter, there are several shortened articles, which end with a linked “more”. A click on it leads me to a site on the landing page, where I can find the whole article. After reading, I want to change back to the whole newsletter just by clicking a link below the full article. I don’t want to switch to the right browser tab by hand.
I hope it is much clearer now… ??
