According to Live Direct Marketing's daily Tranco top-1M scan (July 12, 2026), MsgApp is the SaaS sender for 129 domains — 0.02% of 617,244 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
MsgApp is a software-as-a-service platform that sends email on behalf of its customer domains. It is detected in email infrastructure via SPF include mechanisms published in domain DNS records, making its footprint visible whenever an organisation delegates delivery to its service.
MsgApp's adoption pattern — concentrated in the long tail of smaller sites rather than among global top-tier brands, and predominantly in the .com namespace — indicates it serves a specific market of smaller to mid-sized enterprises. Its frequent co-occurrence with Microsoft 365 suggests it is typically integrated into hybrid email stacks rather than deployed as the sole email provider. For anyone involved in sending or receiving email, this distributed presence means MsgApp is part of the broader ecosystem of third-party platforms handling significant message volume.

As a multi-tenant platform, MsgApp customers share the same underlying IP addresses and domain reputation pools for outbound delivery. This creates a dependency: when you publish an SPF include for MsgApp, you tie your sender reputation to the aggregate sending behaviour of all tenants using those resources. Poor practices or abuse by other customers can degrade the entire pool's reputation and indirectly harm deliverability for compliant senders; similarly, strong practices across the customer base preserve reputation for everyone. This dynamic makes it essential for MsgApp users to maintain rigorous list hygiene, monitor bounce and complaint rates closely, and ensure DKIM and DMARC are properly configured alongside SPF.

It means the domain has delegated outbound delivery to MsgApp's platform; the SPF include alone does not indicate message legitimacy, which should be evaluated via DKIM, DMARC, and sender reputation signals instead.
