Mail guidelines

General guidelines for reducing outgoing mail volumes and costs


The Washington State Auditor’s Office conducted a performance audit in the fall of 2011 to identify strategies state agencies could use to reduce what they mail and save money without sacrificing regular, clear communication. The Department of Enterprise Services has developed the following guidelines to help all state agencies evaluate opportunities to reduce outgoing mail volumes and costs. Included in the guidelines are alternatives to mailing and examples of what agencies should consider when mailing in order to reduce associated costs.

The state of Washington uses various methods to distribute information to customers, constituents, clients, vendors, and the general public. These methods include email, telecommunications, websites, social media and mail. All methods have an associated cost. The best method of communicating information achieves the desired result at the lowest cost.

The following guidelines are intended to help agencies identify the most efficient ways to reach their audiences.

Leading and Best Practices

  • Post information on agency websites.
  • Establish electronic account with businesses and clients.
  • Use email for notifications and communication.
  • Use electronic transfer, direct deposit, and electronic benefit cards for payment of benefits.
  • Combine mailings going to the same address.
  • Mail information less often.
  • Presort mail for lower postage costs.
  • Reduce mailing class to reduce postage rates.

Considerations for determining the best distribution method

  • Are there laws requiring a specific distribution method?
  • Who is the audience/recipient?
  • What types of communications are the recipients capable of receiving?
  • Do you need proof the intended recipient received the communication and how long must proof be maintained?
