Convio

Convio (now part of Blackbaud) is an enterprise-grade fundraising and email CRM built for nonprofits managing complex donor relationships at scale. It handles online giving, peer-to-peer fundraising campaigns, mass email capabilities, and detailed reporting on donor behavior and lifetime value.

Convio works best for larger nonprofits or federated organizations with sophisticated segmentation needs. It leans more toward the fundraising platform side than pure email marketing, making it a stronger choice for organizations where fundraising operations are mission-critical.
