Save & Deliver button not sending the mail in invoice and estimates.

When saving either the invoices or estimates we click the Save & Deliver button but when clicking it, it only saves and it does not send the invoice/estimates email. <img width="565" height="75" alt="Image" src="https://github.com/user-attachments/assets/5ab07037-5402-46e3-bf11-df5ec680b24b" /> But the Send Mail button here works so email is already setup correctly. <img width="1700" height="214" alt="Image" src="https://github.com/user-attachments/assets/22d299c2-b3c4-45e8-aad3-a6420a65040f" />
