What Squarespace handles for non-profits and charities
Online donations, including regular giving. Donation blocks take one-off gifts, and recurring gifts when the site uses Stripe or Squarespace Payments.
Fundraising event tickets. Calendar pages list events, and tickets are sold through Eventbrite widgets or links.
Supporter updates. Newsletter blocks add visitors to a mailing list in Email Campaigns or another connected service.
Volunteer and staff applications. Roles can be listed as collection items, with applications through a form block that accepts a file upload; there is no applicant tracking.
