SPF includes and Copernica authentication
Copernica customers authenticate outbound mail by adding an SPF include record supplied by the platform, enabling receiving mail servers to authorise messages sent through Copernica's infrastructure. This authentication mechanism is standard practice; when paired with DKIM and DMARC, it indicates a professionally managed email sender, and the presence of Copernica's SPF include is neither unusual nor a deliverability concern.
