From 28 July 2025, Royal Mail introduced significant changes to its Universal Service Obligation (USO), the framework that guarantees nationwide delivery at a uniform price. These reforms modernise the service and ensure long-term sustainability, but they also bring important considerations for businesses using direct mail.
At Send DM, we’re here to help you adapt to these changes and ensure your campaigns continue to deliver maximum impact, on time, and budget.
Key Changes at a Glance
1. Second-Class & Economy Mail
- Delivery has moved to a five-day alternating schedule (Monday to Friday).
- No Saturday delivery for these services.
2. First-Class Mail
- Six-day-a-week delivery remains (Monday to Saturday).
3. New Speed Targets
- 90% of 1st class mail should be delivered next day
- 95% of 2nd class mail should be delivered within three weekdays
4. New Reliability Targets
- 99% of first-class mail to be delivered within three working days.

5. Parcel Delivery
- No change to the current USO specification.
What This Means for Your Business
For businesses utilising direct mail, the shift in delivery schedules means timing is now more important than ever. Campaign planning should account for the reduced frequency of second-class and economy mail to ensure your messages land when intended.
This affects:
- Event promotions: Allowing more lead time for invitations or announcements.
- Seasonal campaigns: Factoring in weekday-only delivery for certain mailings.
- Customer communications: Ensuring updates and offers arrive within the right window.
Impact on Costs
Royal Mail has stated that these changes will help manage operational costs and sustain the Universal Service financially. However, changes in delivery patterns may mean businesses need to re-evaluate their mailing approach to avoid unnecessary expense.
That’s where Send DM’s postage optimisation service makes a real difference. We can help you choose the most cost-effective service, plan delivery schedules efficiently, and work with you to integrate hybrid digital elements to maintain high engagement without inflating your budget.
