Uniweb (NO) is a Norwegian mailbox provider that delivers mail infrastructure services for websites and organisations across the Tranco top-1 million. It operates as a primary mail exchanger for its customers' domains.
Uniweb's presence is strongest among smaller and mid-market sites rather than the largest global brands, with particular concentration in the Norwegian (.no) domain space.

Uniweb and Zendesk integration
Uniweb is commonly deployed alongside Zendesk, appearing in the mail stack of smaller organisations that use Zendesk for helpdesk and customer support. This coupling means that senders targeting such sites may encounter Uniweb as the mail endpoint for support emails, ticketing confirmations, and customer-facing correspondence rather than as a primary corporate mail provider.
