There are two event based automatic notifications sent out to backers:
When pre-orders start
An email notification is sent out to committers to let them know that pre-order process has just started and that they’re guaranteed the lowest price including a button that links to the campaign’s page,
When pre-order end
An email notification is sent to backers who pre-ordered to let them know that the campaign has ended and that their pre-order process has completed and their payment is captured.
You can modify both email notification templates and use variables such as campaign name, campaign url, shop name and shop url.
