我刚刚了解了 HTML 的这种新扩展，并想了解一些有关它的知识。
我已经从他们的Playground向我的 Gmail 帐户发送了一个测试到我的 Gmail 帐户，它运行良好。
现在，我使用带有SPF、DKIM和DMARC的有效邮件系统（按照他们的文档中的要求）做同样的事情，当它到达时，它看起来已经坏了。amp-html 甚至与我使用 Playground 构建的版本都不相近。
我错过了什么？
- 我已将邮件列入白名单
- 我允许从发件人（我的 ESP）接收动态邮件
这是我用于测试的模板

## Introduction
The [amp-carousel](/content/amp-dev/documentation/components/reference/amp-carousel-v0.2.md) component allows displaying multiple similar pieces of content along a horizontal axis.

<!-- ## Basic Usage -->
<!-- Use `type="carousel"` to display a list of images as a continuous strip. -->
<amp-carousel height="300" layout="fixed-height" type="carousel">
<amp-img src="https://preview.amp.dev/static/samples/img/image1.jpg" width="400" height="300" alt="a sample image"></amp-img>
<amp-img src="https://preview.amp.dev/static/samples/img/image2.jpg" width="400" height="300" alt="another sample image"></amp-img>
<amp-img src="https://preview.amp.dev/static/samples/img/image3.jpg" width="400" height="300" alt="and another sample image"></amp-img>
</amp-carousel>
<!-- ## Slides -->
<!-- Use `type="slides"` to display a list of images as slides. -->
<amp-carousel width="400" height="300" layout="responsive" type="slides">
<amp-img src="https://preview.amp.dev/static/samples/img/image1.jpg" width="400" height="300" layout="responsive" alt="a sample image"></amp-img>
<amp-img src="https://preview.amp.dev/static/samples/img/image2.jpg" width="400" height="300" layout="responsive" alt="another sample image"></amp-img>
<amp-img src="https://preview.amp.dev/static/samples/img/image3.jpg" width="400" height="300" layout="responsive" alt="and another sample image"></amp-img>
</amp-carousel>
<!-- ## Autoplay -->
<!-- The `autoplay` attribute (type=slides only) advances the slide to the next slide without user interaction, by default it will advance a slide in 5000 millisecond intervals (5 seconds) and can be overridden by the `delay` attribute. -->
<amp-carousel width="400" height="300" layout="responsive" type="slides" autoplay delay="2000">
<amp-img src="https://preview.amp.dev/static/samples/img/image1.jpg" width="400" height="300" layout="responsive" alt="a sample image"></amp-img>
<amp-img src="https://preview.amp.dev/static/samples/img/image2.jpg" width="400" height="300" layout="responsive" alt="another sample image"></amp-img>
<amp-img src="https://preview.amp.dev/static/samples/img/image3.jpg" width="400" height="300" layout="responsive" alt="and another sample image"></amp-img>
</amp-carousel>
<!-- ## Buttons -->
<!-- By default, carousel buttons use inlined SVGs as background-images.
You may override these with your own SVGs or images by using `.amp-carousel-button-prev` and `.amp-carousel-button-next` classes. -->
<amp-carousel id="custom-button" width="400" height="300" layout="responsive" type="slides" autoplay delay="2000">
<amp-img src="https://preview.amp.dev/static/samples/img/image1.jpg" width="400" height="300" layout="responsive" alt="a sample image"></amp-img>
<amp-img src="https://preview.amp.dev/static/samples/img/image2.jpg" width="400" height="300" layout="responsive" alt="another sample image"></amp-img>
<amp-img src="https://preview.amp.dev/static/samples/img/image3.jpg" width="400" height="300" layout="responsive" alt="and another sample image"></amp-img>
</amp-carousel>
<!-- ## Supported Contents -->
<!-- Each of these nodes may also have arbitrary HTML children. -->
<amp-carousel height="300" layout="fixed-height" type="slides">
<div>
<div class="blue-box">
This is a blue box.
</div>
</div>
<div>
<div class="red-box">
This is a red box.
</div>
</div>
<div>
<div class="green-box">

</div>
</div>
</amp-carousel>
<!-- A good use case for `amp-carousel` are image galleries, [here](/documentation/examples/multimedia-animations/image_galleries_with_amp-carousel/) are some examples. -->

我已经阅读了其他解决方案，但那些使用 .NET、C#、Python 和其他关于定制软件来发送此类邮件的解决方案，但是 XCampaign、SalesForce、Selligent 等大型批量电子邮件服务呢？
他们是否需要升级以允许 AMP 发送电子邮件？
