Newsweaver (NE16) is an email service provider handling outbound mail relay for customer domains, identifiable through SPF include mechanisms. It processes transactional, marketing, and bulk mail on behalf of its customer base.
Its footprint concentrates on smaller and mid-market websites — predominantly .com domains — rather than enterprise brands, and it commonly appears in SPF records alongside Microsoft 365, suggesting a complementary role where it handles scale or mail types outside Microsoft's primary offering.

Newsweaver frequently appears in the SPF records of domains also running Microsoft 365, suggesting a split-sender model where transactional or bulk mail is delegated to Newsweaver whilst corporate email remains on Microsoft's platform. This architectural pattern requires careful SPF and DKIM alignment to prevent authentication failures; senders must ensure that each outbound path (Microsoft 365 and Newsweaver) is explicitly authorised in the domain's SPF record and that both signatures validate correctly at recipient.
