。所以我必须将其转换为 table 和 spans。

是否有任何建议，如何通过某些代码使设计在大多数电子邮件客户端中看起来相同？

当前代码如下所示

<div style="background-color: white; margin-right: 9px; margin-left: 9px; padding-bottom:1px; margin-bottom:10px;">
    <table style="background-color: white; border-color: black;padding-bottom:1px; margin-bottom:10px;">
    <tbody>
    <tr>
    <td>
    <h3 style="color: #000000; font-family: 'Open Sans', Verdana, Arial, sans-serif; font-size: 16px; font-style: normal; line-height: 24px; letter-spacing: normal; text-align: left; display: inline-block;"> Hello, </h3>
<br />
    <span style="font-family: 'Open Sans', Verdana, Arial, sans-serif; font-size: 13px; line-height: 18px; font-style: normal; font-weight: normal; color: #787878;"> Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Nulla turpis magna<br />   cursus sit amet, suscipit a, interdum id, felis.

    </td>
    </tr>
    <tr>
    <td><img style="text-align: left; width: 275px; height: 105px; margin: 10px; border-width: 0px; border-style: solid; float: left;" src="https://blog.inpage.cz/obrazek/2/kitten-jpg/" alt="CAD" /></td>
    </tr>
    <tr>
    <td>
    <h2 style="color: #f26503; font-family: 'Open Sans', Verdana, Arial, sans-serif; font-size: 24px; line-height: 36px; text-align: center;"><u>here, lorem</u></h2>
    </td>
    </tr>
    </tbody>
    </table>
    </div>
    <span style="line-height: 0.1; padding:1px; margin:10px;">
    
    </span>
