Hello

Try below code to avoid email notification when try to create new record (version 10.0)

For example if you want to create new task but disable email notification to follower you can reference below code

task = super(Task, self.with_context(mail_notrack=True)).create(vals)

Hope this help you.

Best Thanks,

Hello

If your talking about automatic email sent after you confirm order or invoice. Get in debug mode (in the about openerp window). Then go in the sale order tree. Next to the title there is a combox box. At the end of the list there is edit workflow. In the workflow in diagram view double click on the line between bubble and you will find one that triger an action for email. Remove the action and you will be done. I can't tell you witch one I have remove it!

Ankit H Gandhi's answer worked for me :) thanks

We had  the  same  problem  but  the  previous  suggestion  of  disabling  the  'default'  checkbox  on  the  email subtype  didn't  work  for  us.  

We  eventually found  a  way  with  the  help  of  Odoo  support that  did  work :  

• go to sales application > configuration > quotation template. 
• open the quotation template  you  are  using
• go to the confirmation tab, edit and delete the confirmation mail 

This should prevent any emails sending when the sales order is confirmed.

Look here to disable sending notifications per mail:
