Terms of use

Invite people you know. Zost is for inviting people to real events. Only add people who would expect to hear from you. No spam, no bulk marketing lists, nothing illegal or hateful.

Sending limits. To keep everyone's emails out of spam folders, each account can send a limited number of emails per day. We may suspend accounts that are used to send spam.

Your content. You own your events and guest lists. You are responsible for what you write in invitations and messages.

No guarantee. We work hard to deliver every invitation, but email can be delayed or filtered, so please don't rely on Zost alone for anything critical.
