Copernica is a Dutch email service provider and marketing automation platform, offering email campaign management, customer segmentation, and message delivery services to business organisations.
Analysis of SPF authentication records across large domain datasets reveals that Copernica's customer base is concentrated in the long tail of smaller and mid-market organisations rather than the world's largest brands, with particularly dense adoption in .nl domains. Its frequent co-occurrence with Microsoft 365 authentication mechanisms signals substantial use among organisations operating hybrid mail environments.

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.
