Mailgun 批量发送模板与 Handlebars Expression 中的收件人变量

Question

我正在尝试为我办公室的一个项目探索 MailGun API，但我被 Handlebars 和 Templates 卡住了。

我在 MailGun 控制面板中有以下模板（“mastertemplate”）HTML

<p style="font-family: Open Sans, sans-serif; font-size: 16px;"> 
{{#if Islead}}
<p style="box-sizing: border-box;">Hi %recipient.lead_lastname%, %recipient.lead_firstname%</p>    
{{else if Iscontact}}
<p style="box-sizing: border-box;">Hi %recipient.contact_lastname%, %recipient.contact_firstname%</p>
{{/if}}
</p>

以下是发送电子邮件的 C# 代码

RestRequest request = new RestRequest();
Dictionary<string, Dictionary<string, object>> recipientvariables = new Dictionary<string, Dictionary<string, object>>();
request.AddParameter("domain", MAILGUN_DOMAIN, ParameterType.UrlSegment);
request.Resource = "{domain}/messages";
request.AddParameter("from", "from@email.com");
request.AddParameter("to", "a@yopmail.com");
request.AddParameter("to", "b@yahoo.com");
request.AddParameter("subject","MailGun Variables Testing");
request.AddParameter("template", "mastertemplate");

request.AddParameter("h:X-Mailgun-Variables", "{\"Iscontact\": \"%recipient.Iscontact%\", \"Islead\": \"%recipient.Islead%\"}");

request.AddParameter("recipient-variables","{\"a@yopmail.com\":{\"contact_firstname\":\"Jon\",\"contact_lastname\":\"Doe\",\"Iscontact\":\"true\",\"Islead\":\"false\"},\"b@yahoo.com\":{\"lead_firstname\":\"Van\",\"lead_lastname\":\"Dong\",\"Iscontact\":\"false\",\"Islead\":\"true\"}}"

现在的问题是收到电子邮件时，它们如下所示：

b@yahoo.com 嗨董，范

a@yopmail.com 嗨 %recipient.lead_lastname%，%recipient.lead_firstname%

对于第二封电子邮件，它应该显示：Hi Jon Doe

检查您的电子邮件模板 - 根据the mailgun documentation，条件如下所示

{% if is_birthday %}
<p>Happy Birthday! Use the coupon code BIRTHDAY10 to receive 10% off your next order.</p>
{% endif %}
