Hi its possible when i send an invoice to the customer to hide the first email ? I would like to have just Facturation "system@sent-via.netsuite.com"

was this email sent via script?

not sure that's possible. if you instead just want the customer to see the reply-to address (receivables@your-domain.com), then you'll need to setup DKIM see Oracle Docs - DomainKeys-Identified-Mail-(DKIM)/SuiteAnswer #9428

@Tyn Guardian Yes this email was sent by script @David Byes that's what I think it's not possible. Thanks for the DKIM but it's not really what I need

maybe you can move the other email to BCC instead

Finally i found a solution , i change the email on the employee record with system@sent-via.netsuite.com" then when the invoice is sending , the customer can see only this :Employe Name ("system@sent-via.netsuite.com")
