Events are often the lifeblood of non profit fundraising. But many non profits also have active calendars related to the services they provide - workshops, trainings, seminars and more.
CiviCRM includes a fully integrated Event Management solution. On its own it offers a feature set that matches dedicated event management applications. As with all of CiviCRM, the Event Management module is fully integrated with the contact database and uses the Contribution/Payments module for Events that have fees. And, naturally, CiviMail works seamlessly with Events.
