excel - 使用 VBA 使用 Excel 单元格中的数据发送多封电子邮件

Question

我有一份客户电子表格，其中列出了客户姓名、电子邮件地址、联系人和管理员。我希望能够使用列出客户的行中的数据向每个客户发送单独的电子邮件。

我已经编写了一些 VBA(从其他人那里获得的部分)，但它试图将所有电子邮件地址添加到“收件人”字段，并且每个其他字段都提取所有数据而不是相关行。

我对 VBA 东西还很陌生，非常感谢您的帮助。

如何才能使用仅列出客户的行中的信息为每个客户起草单独的电子邮件。

示例数据:

B 列包含从第 3 行往下的客户名称

C 列包含从第 3 行往下的电子邮件地址

E 列包含从第 3 行往下的联系人姓名

G 列具有从第 3 行往下的管理员名称

这是 VBA:

回答您的问题:

我认为您只看到一封电子邮件的原因是您只创建了一个 OutMail 对象。如果要循环，则需要先设置 object = Nothing，然后才能创建新对象:

Set OutMail = Nothing

看起来您正在创建一个字典，其中将电子邮件字段中的所有电子邮件放在一起，将名称放在一起等。您需要一种方法来循环遍历要发送的每封电子邮件。您可以创建字典数组、创建对象集合或循环保存数据的范围。在这种情况下，循环遍历一个范围听起来是最简单的。

伪代码/代码如下所示:

'instantiate the outlook object. Use:
Set OutApp = CreateObject("Outlook.Application")

'Create your array of dictionaries or return a range with the data
'Let's call it listOfEmails

For each email in listOfEmails:

    'instantiate the mail object. Use:
    Set OutMail = OutApp.CreateItem(0)

    'The block that creates the email:
    With OutMail
        .To = strEmailTo
        .CC = strCCTo
        .BCC = ""
        .Subject = strToday & " - Agreement"
        .Body = strbody
        '.Attachments.Add
        .Display
     End With

    'destroy the object when you are done with that particular email
    Set OutMail = Nothing

Next email


Set OutApp = Nothing

一些一般建议:

将代码分成更小的部分可以帮助使事情更容易修复和阅读。它还使其对于本项目和 future 的项目更具可重用性。我添加此反馈是因为它还可以更轻松地在此处回答问题。

例如:

检查 Outlook 是否打开的函数:

Function isOutlookOpen() As Boolean
'returns true or false if Outlook is open

    Dim OutApp As Object

    On Error Resume Next
    Set OutApp = CreateObject("Outlook.Application")

    If OutApp Is Nothing Then
        isOutlookOpen = False
    Else: isOutlookOpen = True
    End If
    On Error GoTo 0

End Function

发送电子邮件的子例程，您可以从另一个子例程调用:

Sub sendEmail(ByVal recTO As String, ByVal subjectContent As String, ByVal bodyContent As String)

    Dim OutApp As Object
    Dim OutMail As Object

    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)

    With OutMail
        .To = recTO
        '.CC = ""
        '.BCC = ""
        .subject = subjectContent
        .body = bodyContent '.HTMLBody
        .display
    End With

    Set OutMail = Nothing
    Set OutApp = Nothing

End Sub

返回一定范围数据的函数:

Function dataRange() As Range
'Returns the range where the data is kept

    Dim ws As Worksheet
    Dim dataRng As Range
    Dim lastRow As Integer
    Dim rng As Range

    Set ws = Workbooks("outlookEmail.xlsm").Sheets("dataSheetName")
    lastRow = Cells(Rows.Count, 2).End(xlUp).Row

    'still select where the data should go if the data range is empty
    If lastRow = 2 Then
    lastRow = lastRow + 1
    End If

    Set dataRange = Range("B3", "G" & lastRow)

End Function

将所有内容组合在一起的子例程:

Sub main()
'This sub does more than one thing, but I'm asuming it's extremely custom ans still relatively short

    Dim data As Range
    Dim subj As String
    Dim recEmail As String
    Dim body As String
    Dim Row As Range

    'check if data exists. Exit the sub if there's nothing
    Set data = dataRange
    If dataRange.Cells(1, 1).Value = "" Then
    MsgBox "Data is empty"
    Exit Sub
    End If

    'Loop through the data and send the email.
    For Each Row In data.Rows
        'Row is still a range object, so you can access the ranges inside of it like you normally would

        recEmail = Row.Cells(1, 2).Value

        If recEmail <> "" Then 'if the email is not blank, send the email
            subj = Format(Date, "mm.dd.yy") & " - Agreement"
            body = "Dear " & Row.Cells(1, 4).Value & "," & vbNewLine & vbNewLine & _
                "Say Hello World!" & vbNewLine & vbNewLine & _
                "Kind Regards," & vbNewLine & _
                "Mr A Nother"

            Call sendEmail(recEmail, subj, body)
        End If
    Next Row

End Sub
