In some circumstances, especially when PS is integrated with a BackOffice system, we're in the need to disable Order Confirmation email.
That's because the order confirmation is processed by the backoffice system and the user would receive more than one mail for his order.
I've seen that is hard coded without any check on any constant related to a possible configuration.
Would be nice to have a feature to be able to disable some emails in Design > Email theme
It can be done (I think...)
In the CONFIGURE section, click on SHOP PARAMETERS, choose the STATUSES tab at the top, select/deselect the column called SEND EMAIL TO CUSTOMER.
If you want to send a specific email (EVEN THE ONE YOU MODIFIED or CREATED) you may choose it at the EMAIL TEMPLATE column…
it's ridiculous how most of the other platforms offer something like this but prestashop doesn't yet.
