Is anyone else having problems sending gift cards through the ma

Villas - Is anyone else having problems sending gift cards through the mail? Twice in the past month, I emailed gift cards. Both mailings were inside bubble wrapped, manila envelopes and neither were received. One had a tracking number that only showed it left our area, but never made it to Phila. or Conn. If I can't trust my mail to get to where it is to be delivered, what do I do now?
