When I order ball game tickets, how can I get tickets e-mailed to me or sent to me by mail?

We picked them up at the "gate"

I get QR tickets.

Ticketmaster sends qr scanner barcode to your app and they scan at gate

I always purchase tickets from ticket resellers such as Ticketmaster, StubHub, or SeatGeek and each have their own apps where it is easy to show QR codes when entering the park or you can email the tickets to yourself. I'm not sure about having them sent to you by snail mail.

Usually, if you but tickets through TicketMaster, they will allow for electronic delivery to your phone or email delivery. Third party apps (StubHub, Gametime) will also allow for emailing your tickets.
