如何使用Sendgrid调用动态html文件中的姓名和邮件地址？

Question

我需要的！

我需要在 HTML 邮件模板中的任意位置包含邮件地址。

我做什么！

每天发送大约 1000 封邮件，所以我的邮件模板应该是动态的。

我必须上传一个 HTML 设计，它应该从 CSV 文件中获取姓名和电子邮件地址。

获取信息对我来说工作正常，但我需要在 HTML 模板中使用我需要的数据。

请告诉我该怎么做？谢谢

我收到的邮件

Answer 1

在 $personalization->addTo 行之后将其添加到您的代码中：

$personalization->addSubstitution('%name%', "John Doe");

然后您可以使用该变量。

你也可以试试这个：

$mail->addDynamicTemplateDatas([
    '%name%' => 'John Doe',
]);

之后，在您的 HTML:

中使用它

Hello, %name%!
