Quick Answer
Use VBA to automate emails from Excel with Application.MailEnvelope or CDO for more complex scenarios.
Nothing is worse than spending hours sending repetitive emails from Excel data. Imagine you have a dataset of 500 customer emails, names, and order numbers, and you need to send each a personalized email with their order details. By the end of this post, you'll be able to automate this process with Excel VBA, saving you hours of tedious work.
The "Old Way" vs. "Smart Way" Comparison
| Feature | The Manual Way | The Smart Way (VBA) |
|---|---|---|
| Email Personalization | Manual entry for each email | Automated with VBA loops |
| Email Sending | Manual sending for each email | Automated with VBA scripting |
| Error Handling | No error handling | VBA can handle errors and exceptions |

Scenario-Based Example
Imagine you have a dataset with customer emails, names, and order numbers, and you want to send each a personalized email with their order details. You can use VBA to automate this process.
Sub SendEmails()
Dim olApp As Object
Dim olMail As Object
Set olApp = CreateObject("Outlook.Application")
Set olMail = olApp.CreateItem(0)
' Loop through each row in the dataset
For i = 2 To 501
' Set email recipient, subject, and body
olMail.To = Cells(i, 1).Value
olMail.Subject = "Your Order Details"
olMail.Body = "Dear " & Cells(i, 2).Value & ", your order number is " & Cells(i, 3).Value
' Send the email
olMail.Send
Next i
Set olMail = Nothing
Set olApp = Nothing
End Sub
Common Mistakes
One common mistake is not setting the email recipient, subject, or body correctly. Make sure to use the correct variables and syntax.
- Error message: "Object variable or With block variable not set"
- Fix: Set the
olAppandolMailobjects correctly.

Suppose you have a dataset with the following columns:
| Name | Order Number | |
|---|---|---|
| john@example.com | John Doe | 12345 |
| jane@example.com | Jane Smith | 67890 |
You can use the above VBA code to send each customer a personalized email with their order details.
