Why Access appears in this category
The Access Group — UK business management cloud.
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.
Access is a SaaS email delivery platform authorising third-party sending on behalf of customer domains, detected across the Tranco top-1M websites through SPF include mechanisms.
Its footprint is concentrated among smaller and mid-market organisations rather than major brands, distributed internationally across numerous TLDs but led by .com. Frequent coexistence with Microsoft 365 in SPF records suggests Access serves organisations building supplementary email capacity within hybrid stacks.

SPF Authentication and Sender Reputation
Access in SPF records authorises the platform to send on the domain's behalf, but reputation tracking remains domain-specific rather than pooled across the Access customer base. Since Access users are often smaller organisations with limited prior sending history, correct DKIM, DMARC, and SPF alignment is particularly critical for delivery success. Organisations already established with Microsoft 365 may see some reputation benefit from that existing relationship when Access appears in the same SPF record.
