Why Blackbaud Luminate (Convio) appears in this category
Blackbaud Luminate Online — nonprofit fundraising + email.
We classify it as a email service provider 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.
Blackbaud Luminate (formerly known as Convio) is a cloud-based engagement platform operated by Blackbaud, a provider of cloud computing and data security solutions. The platform includes email marketing capabilities used by organisations to manage donor communications, supporter outreach, and member engagement campaigns.
The platform is most commonly adopted by mid-sized and smaller organisations in the nonprofit sector (.org domains), rather than large enterprises. Because Blackbaud Luminate typically operates alongside Microsoft 365 infrastructure in these environments, organisations often maintain hybrid email flows where supporter communications route through Blackbaud whilst internal operations use Microsoft. This dual-path setup introduces considerations for email authentication alignment and sender reputation that infrastructure managers and mail administrators should account for when troubleshooting deliverability issues.

SPF Configuration and Authentication Recognition
Blackbaud Luminate's presence in email authentication is typically visible as SPF includes across smaller organisations and nonprofit domains. Because the platform operates in the long tail of ESP adoption, its sending infrastructure is distributed across many organisations with relatively modest per-domain volumes. Senders using Blackbaud Luminate should prioritise proper configuration of SPF, DKIM, and DMARC records, as this combination of smaller organisational sending patterns and long-tail provider status means that reputation and filtering decisions for Blackbaud Luminate traffic may differ materially from those applied to larger, more widely recognised providers.
