A huge improvement has been made to the flow of correcting bounced email invitations. No more need to delete and re-add guests whose email bounced/was undeliverable to resend their invitation!
Just like in the past, bounced emails will be indicated by red envelope icons on your guest list. Now, you can quickly update their email on the guest list (using the pencil icon).
Then quickly duplicate your invitation to send it to "all guests who's invitation was undeliverable".
For the full guide to re-sending emails to bounced emails, see here.
