Calendar event invites with 3 button reply
Many corporations have their own internal Calendar service.
Apple, Microsoft, Gmail and other ISPs also provide their own Calendar service.
Example: Apple Calendar service
Apple creates and sends the email.
The email is sent from [email protected]. If invites like this will be sent to your Mailing List, then [email protected] needs to be added to the Post Only list.
See the step-by-step instructions for adding to Post Only.
The body of the email contains 3 special buttons.
Often, the button options are Accept, Decline, and Maybe. See Desktop and iPhone examples below.
