Add email templates to your app by simply sending any email to a unique address. After creating a new email template in this way you can immediately view it in the dashboard, edit any necessary links and resources, and start using it right away. This could save you a lot of time migrating email templates to OneSignal. It is a great starting point for creating email templates from examples. You can always login to the dashboard Messages > Templates and update the new template to make sure its reusable with the correct images, links and general clean up.Documentation Index
