EmailEngine

EmailEngine is downloadable software, not a hosted service. Download it from EmailEngine's homepage.

Each EmailEngine instance includes a 14-day free trial that can be activated from the dashboard (you can access it depending on where you installed EmailEngine—for example, http://127.0.0.1:3000/admin).

After the trial, a valid license key is required. Purchase a yearly subscription and generate a license key on the key management page. The license remains valid as long as your subscription is active.
