Hi @marausa, thanks for posting your idea! For the moment there are no plans to introduce editing of the web version post-send as these are technically one in the same. The web version isn’t a copy of the email, it’s just the email itself hosted on a sharable URL. We’d want to make sure that even if a visitor came back to view an email some time after it was sent, that the web version they could visit would match the content in their inbox.
Regarding your second suggestion though, being able to unpublishing the web version, this is something that we’d definitely be interested in looking into. Going to keep this post open for others to provide feedback/upvotes on and keep an eye on it from our side. Thanks again for providing your feedback!
