iCloud Calendar Sender
iCloud Calendar invite sender
Send event invitations to your list from iCloud accounts, with rotation and delays.
Many of your guests use an iPhone, and an iCloud Calendar invite fits right into the calendar they already check. iCloud Calendar Sender sends your event invitation to a guest list from several iCloud accounts, each kept inside Apple's daily limits.
Runs on Windows, so you don't need a Mac to do it.
