Even though we do not offer an automated way to email badges to attendees, you can do so yourself.
When you access the badge printing screen, rather than generating a single PDF for all badges, you can click your attendees one by one and generate a PDF for each. You could then email them.
First you select the desired attendee and create a badge for her/him.
Then download the PDF file that was just generated and email it.
Repeat for every attendee.
