Can multiple registrants of a meeting use the same email address

Description
it is possible for different registrants of a meeting use the same email address and different names?

when I add a registrant named Abby Huston with email abc@zoom.us by calling API
and add the other registrant Lisa Huston with email abc@zoom.us, it will update Abby Huston to Lisa Huston, but not add a new record.

Are emails of registrants of a meeting unique? Is there a setting that allows me to add different registrants with same emails?

Hi @joy.guan, no, registrants are added individually by email address. If you did want to use the same email/inbox, I would use an alias system with individuals identified after a +.

For Abby Huston, you could do: abc+abby.huston@gmail.com
For Lisa Huston: abc+lisa.huston@gmail.com.

This will send emails to abc@gmail.com and add multiple registrants/join URLs
