Slack is a communications tool that helps keep your team's conversations in one place.
Slack is a great communications tool. For many nonprofits it's a tool that can bring a semblance of a work-life balance. Many nonprofits. especially Jewish and Israel based ones, live on WhatsApp and have no way to keep work separate from their personal lives. It's similar enough to whatsapp that onboarding can be pretty simple to start with, and their generous offer for nonprofits makes it almost a no-brainer for teams looking for a dedicated work communications platform.
Slack offers their Pro Plan for free to nonprofits of up to 250 staff.
Slack's free plan is sufficient for many organizations. Nonprofit discounts are excellent, the Pro Plan is free for Nonprofits under 250 people.

Slack Lists
A nice free tool for Slack users. It’s simple, but it can be sufficient if you just want a todo list. I wouldn't use it for project management.
