Hi ​@banoo1960, sorry for the confusion. Just to say it plainly, an email address will always be required when creating a new contact. There’s a simple reason for this. In order to book a meeting Calendly needs to be able to schedule an event  on both the invitee’s as well as the host’s calendars. Since virtually all online calendars require an email address, Calendly also requires an email address so that it knows where to create meetings. Again, sorry if this is giving you any headaches and I hope this helps explain things a little more.
