The document discusses cost savings for UK public sector agencies from sending communications electronically rather than by mail. It provides examples of potential cost savings agencies could see depending on the number of recipients. For an agency with 10,000 recipients, the document estimates they could save over £19,000 per year from quarterly mailings or over £258,000 per year from weekly mailings by switching to digital distribution. In addition to direct mailing costs, agencies could save over £20,000 annually from reducing staffing needs by allowing the public to access information online.
