Description

The Elastic Email add-on is designed for site administrators with active lists, marketing teams, and agencies that run client newsletters, with a connection via API key to the Elastic Email sending service and automatic inclusion of the cancellation tag required by the provider. In Newsletter, the extension forwards email sends through the external service and keeps the unsubscribe request synchronized with the base plugin, helping projects that need to separate campaign creation and delivery infrastructure.

Elastic Email fits projects that already structure subscribers, lists, and campaigns within Newsletter, but prefer to route sends through an external delivery infrastructure.
