Getting Started

All mail processed through LetterStream originates from our facility in Phoenix, Arizona. This article explains how this impacts mailing timelines and envelope labeling, addressing two common customer concerns.

Mail Origination and Envelope Labeling

  • All mail is printed, processed, and mailed from Phoenix, AZ.
  • LetterStream uses a custom USPS permit that does not display the city or state of origin on the outer envelope.

Delivery Time Concerns

  • Sending mail through us will not delay delivery to other parts of the country.
  • Our mail is:
    • Sent to a pre-sort company each evening.
    • Flown directly to the USPS main processing center that night.
  • In some cases, this process may even speed up delivery.

Delivery Expectations

  • The USPS states that First-Class Mail is typically delivered within 3 business days, regardless of the destination.
  • Marketing Mail, however, may experience location-based delivery delays.
  • Important: LetterStream cannot guarantee delivery timelines.
    • Once handed off, mail is in the custody of USPS, and delays can occasionally occur.
