defmodule Plausible.Workers.AcceptTrafficUntil do
@moduledoc """
A worker meant to be run once a day that sends out e-mail notifications to site
owners assuming:
- their sites still receive traffic (i.e. have stats for yesterday)
- `site.accept_traffic_until` is approaching either tomorrow or exactly in 7 days
Users having no sites or sites that receive no traffic, won't be notified.
We make a tiny effort here to make sure we send the same notification at most once a day.
