When you send a meeting invitation to one of your phone contacts, they might receive it in one of three ways:
Sending to an Email Address with CatchApp for iPhone or CatchApp for Outlook Email.
If you send a meeting invitation to someone using their email address, they will receive an email from CatchApp with a URL link to a webpage containing the meeting details. Here, they will be able to view all of the meeting information, and pick from all of the times/dates that you have offered. Once they confirm the meeting, you will be notified.
Sending to a Mobile Number with CatchApp for iPhone.
With CatchApp for iPhone, you can also invite people via SMS. When you send a meeting invitation to someone using their mobile number, they will receive an SMS from CatchApp with a URL link to a webpage containing the meeting details. Here, they will be able to view all of the meeting information, and pick from all of the times/dates that you have offered. Once they confirm the meeting, you will be notified.
