Here's why it works for us:

We are a community-based Food Pantry, and posting the Raffle tickets on our webpage and Social Media has boosted our ticket sales. We no longer have to handle in-person ticket sales. Zeffy has made this process so easy. I can't imagine selling tickets any other way!

One thing that other non-profits can do:

During your event period, make sure you update and send out reminders on Social Media! It's important that ticket holders, as well as those who haven't purchased tickets yet, know that they still have a chance to enter or purchase more tickets.
