编程群发邮件可以通过多种编程语言和库实现，以下是一些常见的方法和示例代码：
1. 使用VBA和Outlook进行群发邮件
示例代码：
```vba
Public Sub SendBatchEmails()
Dim ws As Worksheet
Dim outlookApp As Object
Dim mailItem As Object
Dim lastRow As Long
Dim i As Long
' 初始化
Set ws = ThisWorkbook.Sheets("邮件列表")
Set outlookApp = CreateObject("Outlook.Application")
lastRow = ws.Cells(ws.Rows.Count, 1).End(xlUp).Row
' 遍历收件人列表
For i = 2 To lastRow
If ws.Cells(i, 5).Value = "已发送" Then
SendPersonalizedEmail outlookApp, ws, i
End If
Next i
' 清理对象
Set outlookApp = Nothing
End Sub
Private Sub SendPersonalizedEmail(outlookApp As Object, ws As Worksheet, i As Long)
Dim olMail As Object
Dim mailBody As String
' 创建并发送邮件
Set olMail = outlookApp.CreateItem(0)
With olMail
.To = ws.Cells(i, "B").Value
.Subject = ReplaceTemplateVariables(ws, i)
mailBody = GenerateMailBody(ws, i)
.Body = mailBody
.Send
End With
Set olMail = Nothing
End Sub
Function ReplaceTemplateVariables(ws As Worksheet, i As Long) As String
' 这里可以添加替换模板变量的逻辑
ReplaceTemplateVariables = ws.Cells(i, "C").Value
End Function
Function GenerateMailBody(ws As Worksheet, i As Long) As String
' 这里可以添加生成邮件正文的逻辑
GenerateMailBody = "这是一封个性化的邮件。"
End Function
```
2. 使用Python和smtplib库进行群发邮件
示例代码：
```python
import smtplib
from email.mime.text import MIMEText
from email.header import Header
def send_mass_email(sender, password, receiver_list, subject, content):
创建邮件对象
msg = MIMEText(content, 'plain', 'utf-8')
msg['From'] = Header(sender)
msg['Subject'] = Header(subject, 'utf-8')
try:
连接到SMTP服务器,这里以QQ邮箱为例
server = smtplib.SMTP('smtp.qq.com', 587)
server.starttls()
server.login(sender, password)
for receiver in receiver_list:
msg['To'] = Header(receiver, 'utf-8')
server.sendmail(sender, receiver, msg.as_string())
print("邮件群发成功")
except smtplib.SMTPException as e:
print(f"邮件发送失败: {e}")
```
3. 使用Python和openpyxl库进行群发邮件
示例代码：
