According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), Pepipost (Netcore) is the email service provider (ESP) for 74 domains — 0.01% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
Pepipost, now part of Netcore (a cloud communications platform), is an email service provider that delivers transactional and marketing messages for businesses. The platform serves as an outbound SMTP relay and marketing automation tool, enabling organisations to send messages at scale through its infrastructure.
Pepipost's presence in the email ecosystem is most visible among smaller and mid-market organisations rather than enterprise brands; it appears widely across international domains, particularly .com, and is frequently paired with Google Workspace deployments. For email administrators and security teams, this distribution pattern means SPF lookups may regularly encounter Pepipost include mechanisms, and authentication checking should account for its servers when auditing sender verification chains.

Pepipost's presence in SPF records—often appearing as an include mechanism in the DNS authentication chains of its customers—creates a dependency point in mail flow verification. When a sender uses Pepipost, receiving mail servers must resolve and validate that include during SPF checks, adding a layer to the authentication lookup chain. This is particularly relevant for organisations running their own mail filtering or managing strict SPF policy enforcement, as any misconfiguration or DNS resolution delay involving Pepipost's SPF records can affect delivery of messages from its customers.
