FAQ

Fair questions, straight answers

  • What happens when a campaign goes viral?

    Nothing - that's the point. We never bill per click or per signup. Your only limit is the number of events you create, which is fully in your control.

  • How do public event lists and subscriptions work?

    A public event list presents an ongoing program in a clear date-led view, while a hosted subscription calendar lets recipients follow that program over time.

  • Does the trial require a credit card?

    No. The full-featured trial lasts 7 days and does not require a credit card. You only incur costs when you explicitly choose a paid plan.

  • Can our team collaborate without per-seat charges?

    Yes. Every current plan includes unlimited team members and unlimited user actions. Plan limits center on the number of new events created each month.

  • Can we use our own brand and domain?

    Branding removal is available on Regular. Regular includes one custom domain; Enterprise includes ten. Hobby does not include a custom domain.
