Nonprofits and fundraising teams reach a fraction of their potential donor base because outreach capacity is limited by volunteer hours and staff time. Synthesys automates donor outreach, pledge follow-up, lapsed donor reactivation, and event communication—so your team focuses on the relationships that move the mission forward, while Synthesys handles the volume.

Synthesys is trusted by:
Donor Outreach & Pledge Campaigns
Run high-volume outbound donor campaigns—annual giving appeals, matching gift drives, and capital campaigns—without requiring additional volunteer callers.
Lapsed Donor Reactivation
Proactively contact donors who haven't given in 12+ months—personalised outreach at the right time, with the right message to re-engage their support.
Pledge Fulfilment Follow-Up
Contact donors with outstanding pledges at the right intervals—politely, professionally, and consistently—without straining volunteer relationships.
Event & Fundraiser Communication
Manage event registrations, send reminders, and follow up with attendees post-event—automating the communication that currently takes significant staff time.
Run Annual Giving Campaigns at Scale Without a Phone Bank
Synthesys contacts your full donor list—not just the segment your volunteer callers can reach—with consistent, compelling outreach for every annual giving drive.
Reactivate Lapsed Donors Before They Forget You
Donors who haven't given in over a year are contacted automatically with personalised outreach—re-engaging a revenue stream that currently sits dormant.
Follow Up on Pledges Without Awkward Manual Outreach
Outstanding pledges receive professional, timely follow-up calls at configured intervals—improving fulfilment rates without straining donor relationships.
