An event organizer creates an online invitation through the website via a simple interface. This online invitation is colloquially referred to as "an Evite". The host enters e-mail addresses of prospective guests and Evite sends e-mails to the guests. Each guest is in one of four categories: "Attending", "Not Attending", "Maybe", and "Not yet replied". Guests move themselves from the "Not yet replied" category to one of the three "replied" categories and can write additional comments.
- Hosts may send an automatic reminder e-mail in the days prior to the event.
- Hosts can determine through the web site whether a guest has viewed the invitation or not.
The HTML page for the invitation may have various stylistic features chosen by the inviter. These include setting, color, layout, and renaming the four guest categories.
Hosts may opt to send guests updates when other guests RSVP for the event, or when the event details are changed.
