关于 AMP
AMP（加速移动页面） 是 Google 基于 HTML、CSS 和 JavaScript 创建的开源框架。它能够构建加载更快的轻量级邮件。AMP 提供了诸如轮播、表单、图片等多种组件。除了快速之外，AMP 邮件还能在邮件客户端内呈现完整交互式邮件，用户可以直接在邮件中填写表单或回复调查，而无需离开客户端。
使用 AMP HTML 邮件
Aspose.Email 提供了 AmpMessage 它代表一个 AMP 邮件。Aspose.Email 提供了许多类来向 AMP 邮件添加组件，如 AmpImage、AmpCarousel、AmpAccordion、AmpForm 等。完整的类列表可在 Aspose.Email.Amp 页面。以下代码片段演示了使用 Aspose.Email API 创建、保存和更新 AMP 邮件。
