The native plugin is built for sales: it turns emails into CRM leads, and it only recognises senders who already exist in Odoo. Dalgone is built for the back office — it resolves any sender, including unknown senders and shared inboxes like orders@ or ap@, to the right company, shows their sales orders, purchase orders, invoices, vendor bills and deliveries, and logs the email back to the record in one click. No server module, no admin setup.
