I also liked the landing page.

Constructive criticism, might just be me: I would lose the phrase "jam on email"... something about it (too folksy?) rubbed me the wrong way.

Perhaps something simpler like "Say hello to Jelly, team email done right."

For a counterpoint - I like it! "Jam" reminds me of jam sessions and FigJam, both pleasant experiences.
