Webinars

Learn it live

We hosted two live sessions this month to help you get up and running — from onboarding new supporters to publishing press releases with NucleusWire.


Feature Spotlight

Email Subscription Management (ESM)

ESM was our biggest release of the month — a rebuilt system for managing how your audience subscribes, updates preferences, and stays engaged. We published a full resource hub to go with it.

ESM gives you granular control over subscriber lists, preferences pages, and segmentation — all in one place. Whether you're onboarding new supporters or cleaning up your audience, these guides cover everything from setup to FAQs.


New Resources

Fresh from the help center

Alongside this month's releases, we published new guides covering email analytics, MCP integration, and volunteer management.


Questions about any of these updates? Our team is here to help. Head to the help center to explore every guide, or reach out directly — we're always building, and we want to make sure you're getting the most out of every release. (Must be logged in to view resources)
