Why haven't my mailers arrived in the mail?
Your mailers are mailed via Standard Mail. It is hard to predict when the letter will arrive because Standard mail is processed on a lower priority basis than First-Class mail. We've seen letters delivered in as little as 2 days and letters delivered in more than 14 business days. Generally speaking, national mail is typically delivered in the period somewhere between seven days and three weeks.
USPS Service disruptions can also cause your mail to be delayed. Natural disasters (like recent fires or hurricanes) can cause major delays. You can check the status of USPS Service disruptions HERE.
