Why Netcore Cloud (Pepipost) appears in this category
Netcore Cloud — customer engagement and email API.
We classify it as a email service provider from include: mechanisms in the SPF record matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
Netcore Cloud, marketed as Pepipost, is an email service platform providing transactional and bulk sending infrastructure. It appears throughout the email routing ecosystem via SPF include mechanisms, which allow domains to authorise Netcore Cloud to send mail on their behalf without publishing every authorised IP address directly.
The service is concentrated amongst smaller and mid-market websites in the .com namespace, rather than the largest global brands. When analysing email infrastructure, you typically observe Netcore Cloud SPF includes alongside generic or unmatched MX record patterns—a standard configuration where organisations delegate outbound delivery to a third-party platform whilst maintaining their own inbound mail handling. For those diagnosing deliverability problems or assessing email source reputation, recognising these patterns is essential, as they reveal how a domain's own DNS declarations interact with its infrastructure partners.

SPF authorisation and third-party routing
Netcore Cloud's footprint in email infrastructure is primarily visible through SPF include directives, which appear in the published sender policy for domains using the platform. The concentration of Netcore Cloud amongst smaller and mid-market senders means reputation and monitoring systems encounter it regularly in this segment, though less frequently in dominant enterprise mail flows. Effective diagnostics of deliverability issues requires understanding how these third-party SPF includes are evaluated by ISPs and reputation services, and how the reputation of both the sending domain and its infrastructure partner contribute to overall message acceptance.
