problems sending out emails for meetings

Zoom lets you create meetings, it does not email attendees automatically. You have a few options. You can copy the link and paste it into an email. You could use API to send an invite when creating a meeting. There are also many scheduling apps that let you invite attendees when scheduling a meeting. Looking through the Zoom marketplace one option is Salepager, which lets you email an invite and reminders when creating a Zoom meeting.
