How do I use the Shopify Newsletter app to send newsletters to my customers?

To use the Shopify Newsletter app to send newsletters to your customers, follow these steps: Log in to your Shopify account and click on the "Apps" tab in the left-hand menu. Click on the "Shopify Newsletter" app to open it. To create a newsletter, click on the "Create newsletter" button in the app dashboard. Use the app's editor to customize the content of your newsletter. You can add text, images, and other elements, and you can choose from a variety of templates and design options. When you're finished creating your newsletter, click on the "Send" button to send it to your customers. In the "Send options" window, select the recipients for your newsletter. You can choose to send the newsletter to all of your customers, to a specific group of customers (such as those who have made a purchase in the past), or to a custom list of recipients. Choose whether you want to send the newsletter via email or SMS, and then click on the "Send" button to send the newsletter. That's it! Your newsletter will now be sent to the selected recipients.
