Landing page - the primary problem I had was trying to understand what your product does. The phrase "shared by your Twitter friends" implies that you have introduced a new concept ("friends"), perhaps a group of like-minded individuals who are curating Twitter on behalf of one another. In other words, unless a Tweet is shared by at least one member of my "friend" group, I will NEVER see that Tweet in my email. This is potentially very valuable to consumers who have a limited amount of free time, and only want to read manually vetted content. However, I think your product doesn't actually do that. Instead, your product provides "A summary of your Twitter home timeline" - and that may, in general, include niche topics that are very important to me but not relevant to any of my friends. This is also valuable but has a different audience. Ideally, the landing page would make it clear which of these product variants I'm actually buying.

Other comment - I think https://murmel.social/top violates the Twitter brand guidelines, and the Twitter company will eventually object. Their guidelines specify "credit Twitter by using the our logo" (from the https://about.twitter.com/content/dam/about-twitter/en/brand... page). Every Tweet must include the bird picture. Your https://murmel.social/top page is too easily misinterpreted to mean that some of the content is sourced from Twitter but other content is sourced from elsewhere, because the bird picture appears intermittently.
