Hi Rayno,

Did you found any solution for this?

I agree this is important for Odoo to support. I'll call it "multiple recipient emails."

In templates you can list multiple email addresses separated by commas, and in the email composition window you can select multiple partners, and it looks like most email clients and gives the impression that all the recipients will see the same email. Unfortunately everyone gets their own email.

There are two obvious down sides:
 - It's hard to know who else received the same email (a way to help below, but still a workaround)
 - There's no way to Reply All

I would appreciate if this would get an answer from Odoo. I will mention that I see this behaviour on my different client DBs that are all running on Odoo.sh. I don't know if this is a behavior of the Odoo mail server that needs to be corrected?

I did add the following code in the body of the email template, just to help people know who else the email had been sent to.

To: 
% for iter in object.message_partner_ids
${iter.email},
%endfor

Hey Geoff, I really like your workaround. Do you know of a way to implement this so that all emails that are sent from Odoo, by default includes this "workaround" or can it only be done on custom email templates that staff need to choose?
