ROBINS, Iowa (KCRG) – Some people in Robins said they went several days without receiving their mail earlier this month. Now, weeks later, it still hasn’t been delivered. Martin Barrett said he uses a free service from the Postal Service called Informed Delivery. It emails participants a preview of what they’re going to get in their mailbox later that day. Barrett said earlier in January, there were several days he was notified mail was on its way, but then it never showed up.
