SendGrid營銷電子郵件延遲？

Question

步驟

1. 創建收件人列表
2. 創建營銷電子郵件
3. 添加電子郵件，收件人列表
4. 指定收件人列表營銷電子郵件

當調試慢慢地，我管理從sendgrid傳遞所有成功消息的步驟。

但在非調試模式下，儘管我向收件人列表成功添加了電子郵件（結果從sendgrid返回），但在步驟4中，我收到了結果返回沒有收件人的列表。我刷新了瀏覽器，並在收件人列表中看到了電子郵件。

我試圖把timer.interval開始之前處理第4步，但也得到相同的結果返回。

VB ProcessHandler代碼

' 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功能代碼

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，列表計數可能需要一點時間來更新。 「強制」它的一種方法是查詢完整列表，這會觸發系統計數，並更新計數，然後允許您正確連接它。
