Remove sentence from confirmation email

Can you/I remove the following: "You can edit this submission and view all your submissions easily." from auto confirmation email?

Also, can i opt not to do a confirmation email? 

Thanks 

You can do it by opening the email wizard, once there you may edit or simply delete the email notification: 

If you click on the edit button, you will get this window where you can simply remove the text you do not want in your email, after making all the changes, please do not forget to click on the save button: 

Hope this helps.
