Why WeFact appears in this category
WeFact — Dutch invoicing software.
We classify it as a SaaS sender 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.
WeFact is a SaaS platform that sends transactional email on behalf of customer domains. It is detected across the internet through its presence in SPF (Sender Policy Framework) records, where it represents a delegated sending authority for the domains that use it.
WeFact's footprint is concentrated in the Netherlands and appears more frequently among smaller and mid-market organisations than the largest global brands. Its regular co-occurrence with Microsoft 365 environments suggests it often functions as a complementary sending platform in hybrid scenarios, making it a relevant consideration for anyone troubleshooting email authentication or deliverability on .nl-based domains.

SPF authentication and sending infrastructure dependencies
WeFact's role in email delivery is determined by its position in the SPF chain of the domains that use it. Any domain leveraging WeFact for outbound email delegates sending authority to the platform's IP ranges, creating an infrastructure dependency; if WeFact's IP reputation or sending practices deteriorate, all downstream domains can experience deliverability impact. For email receivers and deliverability professionals, recognising WeFact in an inbound message's authentication trail clarifies the true sending path and informs decisions about reputation assessment and filtering policy.
