Shopify introduced Express Checkout Buttons in Shopify Email
Shopify has just introduced Express Checkout Buttons in Shopify Email. With the help of this tool, you can include an express checkout button in your email campaigns and allow customers to use Shop Pay to complete their purchases quickly.
You can select a product or product variant, and create a Check out now button. If you have Shop Pay enabled on your store, then a Buy with Shop Pay button also displays.
Customers that use express checkout skip the product and cart pages in favor of a quicker checkout process. Conversion rates for customers can be raised by using expedited checkout.
The express checkout buttons apply only to a single product, but you can add more than one express checkout section to an email.
