[英]Outlook email performance slow using Excel VBA
Outlook 发送电子邮件的速度非常慢。
此外,我的 CPU 为 15-20%,而我的 16G ram 的利用率为 50%……所以这可能是代码性能或资源分配的问题。
我在下面包含了我的代码:
'my code
Sub SendMail(what_address As String, subject_line As String, mail_body As String)
Dim olApp As Outlook.Application
Set olApp = CreateObject("Outlook.Application")
Dim olMail As Outlook.MailItem
Set olMail = olApp.CreateItem(olMailItem)
With olMail
.To = what_address
.Subject = subject_line
.BodyFormat = olFormatHTML
.Attachments.Add "C:\Users\User\Documents\Association\Event Brochure\BROCHURE.pdf"
.HTMLBody = mail_body
.Send
End With
End Sub 'Tells outlook to send an input, with an attachment I selected
Sub SendMassMail()
row_number = 1
Do
DoEvents
row_number = row_number + 1
Dim mail_body_message As String
Dim name As String
Dim mrmrs As String
Dim company_name As String
mail_body_message = Sheet1.Range("I2")
name = Sheet1.Range("B" & row_number)
mrmrs = Sheet1.Range("C" & row_number)
company_name = Sheet1.Range("D" & row_number)
mail_body_message = Replace(mail_body_message, "replace_mrmrs_here", mrmrs)
mail_body_message = Replace(mail_body_message, "replace_name_here", name)
mail_body_message = Replace(mail_body_message, "replace_company_here", company_name)
Call SendMail(Sheet1.Range("A" & row_number), "Event Sponsorship", mail_body_message)
Loop Until row_number = 500
End Sub
这段代码是我在 Excel 表格中创建的两个宏,其中包含 A 列中的电子邮件地址、B 列中的姓名、C 列中的先生/夫人、D 列中的公司,最后是单元格 I2 中的消息正文,其中包含关键字为每个收件人更换。
现在关于资源分配。 在任务管理器中,我给 excel.exe 和 Outlook.exe 一个高优先级。
我的代码运行很糟糕是因为我在使用 Call SendMail 时调用了另一个函数吗?
因为我使用了 DoEvent,所以我的代码运行很糟糕吗? 这是我知道的唯一方法……所以如果你建议一个与 DoEvent 不同的方法,请解释它的作用。
这是我快速重写的地方:
DoEvents
删除到注释中。 如果您绝对需要能够在运行时中断代码执行,那么您将希望将DoEvents
保留在循环中。 如果你不在乎,只是想让它运行得尽可能快,那就把它放在一边。 我建议(正如@JoshEller 指出的那样)首先将这些电子邮件保存为草稿可能是更好的选择。 然后,您可以从 Outlook 手动发送,以发现在为时已晚(令人尴尬)之前可能已犯的任何错误。Sub SendMassMail()
