我正在发送 html 电子邮件（上面的代码），但邮件应用程序在 gmail.com 和 outlook.com 中不正确。他们都在 a 标签周围添加了 p 标签，并在 img 标签周围添加了 span 标签，就像这样;
<td>
<p class="some class name"
<a href="http://www.google.com" target="_blank">
<span class="some class name">
<img src="images/img_10.png" alt="" style="display:block;" width="600" height="31" border="0" />
</span>
</a>
</p>
</td>
因此看起来TR标签之间的差距。我该如何解决这个问题？
对所有图像使用 style="margin: 0; border: 0; padding: 0; display: block;"。
此外，向页眉样式标记添加table td {border-collapse: collapse;}可能有助于使用 Outlook。
