You want to invite your customers to a personal appointment? It would be an extra service to attach a calendar item to your email so they can add it to their calendar automatically. With this module you will receive an extra campaign object which will generate the ICS files based on fixed or variable fields. This way everyone will get their own personalized ICS file. See our manual for more information.

If it's for a one-time event, this module is not necessary as only one file needs to be available. Please ask your account manager for the possibilities.
