Can I send the invitation link through my own email?

The invitation link is personalized - you can see the link per participant in the 'Login Link' column in the detail report. If you can create a mail merge with the individual link, then you can send the links so.

Alternatively, you can send the participants the login link, login name and login password. If you set login name to email and give the same password to all, you can put the login link in the email (same for everyone), the hint that the login name is the email and the same password for all.

If you do not upload participants in yve, you can simply start a public registration and send the public registration link.
