Customizing the Invoice Email's 'Thanks for Your Order' Text
By default your customers' invoice emails have a "Thanks for your order!" message included along the top. If you do not change anything here, the invoice emails have a burnt orange message that reads "Thanks for your order". Adding your own message can make it sound more personalized and match the branding of your store.
For more ways to add branding and personalization to yoru emails, see Customizing Email Templates.
