You can use the voucher as soon as payment for it has been taken and you have arrived at the final screen showing the voucher number.
Yes and no.
The vouchers, even when issued without incident, still sometimes can take a few minutes to become available to "redeem" (eg: you can take the PNR from the voucher confirmation page, go to "Redeem Voucher" and get a message about processing). Normally this only takes a minute or two, but sometimes the vouchers can get stuck in limbo (see other posts on this)
I usually give it 2 minutes and go to redeem myself.
You can almost always access a voucher before the email arrives
YMMV
