我正在为新用户编写 html 欢迎电子邮件，但它不起作用。当我发送它时，它会将 html 代码显示为文本，而不是呈现实际的 html。我从 Mailchimp 的模板开始制作模板的 html，所以我很惊讶它不起作用。此外，当我使用 Putsmail.com 和 emailonacid.com 发送电子邮件时，它看起来还不错。

但是，在生产中，电子邮件发送并且 html 在电子邮件中显示为文本，如下所示（来自registration_confirmation.html.erb）：

我的邮件：

def registration_confirmation(user)
  @user = user
  subject     "Welcome #{@user.first_name}!"
  from        "info@foobar.com"
  recipients  @user.email
  sent_on     Time.now
end

从用户注册模型调用：

Notifier.registration_confirmation(user).deliver

您似乎缺少内容类型：

def registration_confirmation(user)
  @user = user
  subject       "Welcome #{@user.first_name}!"
  from          "info@foobar.com"
  recipients    @user.email
  sent_on       Time.now

  # Set content-type header
  content_type "text/html"
end

它默认为text/plain，因此您必须为 HTML 或多部分消息显式设置它。
