What you get
Mailchimp's dashboard shows you one campaign at a time. Loony accumulates every send into a Postgres database so you can query across months, compare segments, and spot trends the UI hides. Scheduled syncs keep the data fresh without cron jobs. Your agent can answer 'Which subject-line pattern gets the best click rate?' because the history is all in one place.
