SendGrid营销电子邮件延迟？

Question

步骤

1. 创建收件人列表
2. 创建营销电子邮件
3. 添加电子邮件，收件人列表
4. 指定收件人列表营销电子邮件

当调试慢慢地，我管理从sendgrid传递所有成功消息的步骤。

但在非调试模式下，尽管我向收件人列表成功添加了电子邮件（结果从sendgrid返回），但在步骤4中，我收到了结果返回没有收件人的列表。我刷新了浏览器，并在收件人列表中看到了电子邮件。

我试图把timer.interval开始之前处理第4步，但也得到相同的结果返回。

VB ProcessHandler代码

' Add email and name to recipient list 
If oSendMarketingEmail.AddEmailToList(oItemDetails.Email, oItemDetails.Full_Name, sRecipientList) = False Then Exit Try 

' Wait for the email and name added to recipient list 
Dim timer As New Timers.Timer 
timer.Interval = 20000 

' Assigning recipient list to marketing email 
    If oSendMarketingEmail.AddListToMarketingEmail(sMarketingEmailName, sRecipientList) = False Then Exit Try 

VB功能代码

Public Function AddEmailToList(sEmailAddress As String, sName As String, sRecipientList As String) As Boolean 

     Dim ResultsHTML As String = "" 

     Dim URL As String = (Convert.ToString("http://sendgrid.com/api/newsletter/lists/email/add.xml?list=") & sRecipientList) + "&data=" + "{""email"":""" + sEmailAddress + """,""name"":""" + sName + """}" + "&api_user=" + SendGridUserName + "&api_key=" + SendGridPassword 
     Dim SendGridResponse As String = PerformHTTPGet(URL) 
     ResultsHTML += (Convert.ToString("Adding email to List: ") & SendGridResponse) + "<br/>" 

     ' Check respond status - success 
     If Not ResultsHTML.Contains("insert") Then logger.log.Info(ResultsHTML) : Return False Else Return True 

    End Function 


    Public Function AddListToMarketingEmail(sMarketingEmailName As String, sRecipientList As String) As Boolean 

     Dim ResultsHTML As String = "" 

     'Assign list to marketing email 
     Dim URL As String = (Convert.ToString((Convert.ToString("http://sendgrid.com/api/newsletter/recipients/add.xml?name=") & sMarketingEmailName) + "&list=") & sRecipientList) + "&api_user=" + SendGridUserName + "&api_key=" + SendGridPassword 
     Dim SendGridResponse As String = PerformHTTPGet(URL) 
     ResultsHTML += (Convert.ToString("Assigning Marketing Email to List: ") & SendGridResponse) + "<br/>" 

     ' Check respond status - success 
     If Not ResultsHTML.Contains("success") Then logger.log.Info(ResultsHTML) : Return False 

    End Function

在SendGrid，列表计数可能需要一点时间来更新。 “强制”它的一种方法是查询完整列表，这会触发系统计数，并更新计数，然后允许您正确连接它。
