Opera automatically appends a signature to every email you write.
More Email Quick Tips
By default, this signature includes some self-praise (Opera's, not yours). We will forgive this shameless plug if Opera lets us replace it with our own shameless plug easily. And it does!
To edit your email signature in Opera:
- Select Tools | Mail and chat accounts... from the menu.
- Highlight the account whose signature you want to change.
- Opera maintains a different signature for each account.
- Click Edit....
- Go to the Outgoing tab.
- Type your signature in the Signature text field.
- You don't have to include the standard signature delimiter. Opera will insert it automatically.
- Click OK.
- Click OK again.
