Zeffy

Zeffy combines email marketing, donor relationship management, donation forms, and ticketing into one free platform designed specifically for nonprofits and social enterprises. The platform charges no platform fees on donations, keeping more money in your mission's hands. You'll find automated email campaigns, segmentation by donor type, and built-in analytics for tracking engagement and revenue.

Zeffy works well for smaller to mid-sized nonprofits that want all the core tools without subscription costs, and for organizations just getting serious about email marketing automation. It's particularly strong for event-driven fundraising and peer-to-peer campaigns where you need ticketing alongside donor communications.
