When a domain publishes an SPF include for Maropost, inbound mail filters treat that domain's reputation as partly contingent on Maropost's infrastructure reputation. If Maropost's IP addresses carry a poor reputation from spam, phishing, or complaint spikes, all domains using the platform can face degraded delivery — regardless of their own sender practices. Rigorous authentication (SPF, DKIM, DMARC) on your domain keeps the reputation boundary clear and helps distinguish your brand's standing from Maropost's collective user behaviour.
