SendClean is an email service provider that delivers transactional and marketing email on behalf of organisations, and is identified in email authentication records via Sender Policy Framework (SPF) include mechanisms that appear across thousands of domains worldwide.
SendClean serves predominantly smaller and mid-market organisations rather than enterprise brands, with a customer base distributed internationally across multiple top-level domains, concentrated particularly on .com registrations. The platform commonly appears in SPF records alongside Microsoft 365 configurations, reflecting its role as a supplementary email service for organisations that have standardised on Microsoft's email platform.

SendClean is deployed as an SPF include mechanism, allowing organisations to authorise it without hardcoding IP addresses into their domain's SPF record. Because SendClean operates shared infrastructure serving many customers, an organisation's email reputation and deliverability depend partly on the sending practices of other SendClean users—a characteristic of shared ESP infrastructure that becomes more significant when SendClean is one of several mail services authorised for a domain.
