Does USPS deliver on Sunday? NoâUSPS does not deliver regular mail (First-Class, Marketing Mail, Periodicals) on Sundays. However, USPS Priority Mail Express guarantees delivery seven days a week, and through the Amazon Sunday program, USPS delivers Amazon-fulfilled Prime parcels on Sundays in eligible ZIP codes.
Meeting customer expectations for fast, reliable delivery is critical for Amazon, Walmart, DTC, and dropshipping sellers alike. Yet many carriers only ship MondayâSaturday, leaving Sunday orders in limbo and increasing cart abandonment risk over weekends. In this post, we'll map out every major U.S. carrier's weekend offeringsâso you can build a true seven-day logistics network that keeps your shoppers happy and your reviews glowing.

User Pain Point: Weekend Orders Falling Through the Cracks
Imagine a shopper who clicks "Buy Now" on Saturday nightâexpecting a Sunday dropâbut your chosen carrier doesn't run on Sundays. That lost convenience often translates into a canceled order or a one-star review. For high-velocity channels like Amazon and Walmart, WEEKEND SUITABILITY can make or break your seller metrics.
Ideal Solution: A True Seven-Day Logistics Network
By mixing and matching carriers that cover Sundays, you can create a seamless delivery promise:
Reserve USPS Priority Mail Express for your highest-value, time-sensitive SKUs.
Leverage Amazon Logistics on Prime-eligible listings to unlock built-in weekend runs.
Dial in regionals (OnTrac, LaserShip) for cost-effective Sunday coverage in specific zones.
Use on-demand options like Roadie for occasional rush orders outside standard windows.
Product Integration: Building Your Multi-Carrier Workflow
To stitch carriers into one cohesive system:
Inventory tagging: Mark SKUs by priority (urgent vs. standard) so your order management software auto-routes them.
Zone mapping: Define geographic rulesâe.g., West Coast Sunday orders go OnTrac, East Coast go LaserShip weekend service.
Rate shopping: Automate live rate checks on checkout to show customers real Sunday-eligible options.
Label automation: Integrate with your OMS (Shopify, ChannelAdvisor, etc.) to generate the correct carrier label instantlyâno manual switching.
Choosing Logistics by Product Category
Different types of products have unique shipping needs. Match your category to the right carrier mix:
Lightweight, Low-Value Items: USPS First-Class or FedEx Home Delivery for cost-efficiency; weekend coverage via FedEx Home Delivery's Sunday service.
High-Value Electronics & Luxury Goods: UPS Next Day Air, USPS Priority Mail Express, or UPS Express CriticalÂŽ for guaranteed speed and insurance options.
Perishables & Temperature-Sensitive Items: Amazon Fresh for groceries, FedEx SameDayÂŽ with refrigerated options, or local cold-chain couriers for freshness.
Bulky Furniture & Large Items: UPS Freight, FedEx Freight, or LTL carriers; Roadie for same-day local deliveries of oversized goods.
DTC & Brand-Building Shipments: FedEx Home Delivery for branded packages, Amazon Logistics for Prime-exposed DTC offers, and branded tracking pages for engagement.
Dropshipping & International Sourcing: DHL Express, FedEx International Priority, or USPS Priority Mail International with Sunday pickup options.
Further Tips: Optimize Packaging, Negotiate Rates & Plan for Peaks
Package dimension planning: Use the smallest footprint that still protects to avoid dimensional-weight surcharges on express services.
Negotiate volume discounts: Even regionals offer tiered pricingâaggregate weekly volumes for better deals.
Peak season strategy: Line up Sunday-ready backup carriers before Q4 surcharges hit.
Customer communication: Clearly display Sunday delivery options at checkout and in post-purchase tracking emails to set accurate expectations.
