Text to donate is used by any organization that collects contributions from a broad audience — especially when timing and ease of giving matter:
Nonprofits and charities running annual campaigns, capital drives, or membership appeals. Disaster relief organizations that need to mobilize donations in hours, not weeks. Religious organizations collecting tithes and offerings from their congregation. Live event fundraisers — galas, telethons, concerts, and walkathons — where you have a captive audience and a narrow window. Political campaigns collecting grassroots contributions from supporters.
