Media and text
Start with a clear image and concise supporting text. For example, a product notification could include a product image, its name and a link to view details. Supported file formats and size limits depend on the sending service and destination network. Confirm the accepted formats and maximum file size for your intended route before preparing the final asset. Keep a smaller version available for routes with tighter limits. Do not rely on text embedded in an image for essential details. Include the business name, the purpose of the message and the next step in the accompanying text.Prepare the content
