Here's what each email from Gift Off means and whether you need to do anything.
"Thanks for your order"
Your order has been placed. This email is also your receipt. Nothing to do.
"Your order is processing"
Your payment went through and we're getting your gift card from the brand. It usually arrives within minutes. Nothing to do.
"Your order is nearly ready"
Your order is having a quick security check. Look for a second email asking you to verify your payment method, then reply with the 4-digit code from your bank statement. See How do I find the 4-digit code?
