Every Mailer Your Clients Need — One Vendor, One PO, Consistent Bulk Pricing
3PL operations don't ship one product — they ship everyone's. On any given day your pack stations might be running apparel for one client, electronics for another, and subscription boxes for a third, each with different packaging needs. MailersUSA carries the full range in one place: POLYJACKET® poly mailers, AIRJACKET® bubble mailers, ECOJACKET® paper and eco mailers, MAILJACKET® rigid mailers, and COOLPAC® insulated mailers — all from one vendor, at bulk case pricing, so you're never juggling multiple suppliers to keep every client's SKU mix in stock.
Whatever your clients are shipping — apparel, electronics, subscription boxes, perishables, or flat media — there's a MailersUSA mailer built for it. Every SKU we carry is shown below, organized by category, with a direct link to shop it. And because 3PL volume rarely looks like a typical order, every case-count tier is priced to reward scale, with custom quotes available once you're ordering across multiple clients or SKUs at once.
Bulk Orders & Custom Quotes for 3PL Accounts
3PL volume is different from a single-brand order — you're stocking multiple client SKUs at once, and your case counts scale with every account you onboard. MailersUSA case pricing already rewards volume on every product page, and for larger or multi-SKU orders our team will work with you directly:
- Consolidated quotes across every mailer type your client roster needs — poly, bubble, eco, rigid, and insulated — on one order
- Volume-tiered case pricing that improves as your total order size grows
- Support setting up recurring or standing orders so restocking doesn't fall on one person's to-do list
Contact our team for a custom volume quote across your full mailer mix, and we'll send you a discount code to apply in your cart — you check out right here on mailersusa.com like any other order.
Request a Custom QuoteWe Understand 3PL Operations
Running a 3PL means your packaging has to work for every client on your floor, not just one brand.
Common challenges 3PL operators face:
- Multiple client brands, each with different packaging requirements, running through the same pack stations
- Volume that scales unpredictably as clients onboard, grow, or run promotions
- Pressure to standardize SKUs and reduce pack-staff training time without compromising protection
- Keeping every client's mailer type in stock without managing a dozen separate vendor relationships
Carrying every mailer type from a single supplier means one purchase order, one shipment, and consistent bulk pricing — no matter how many client brands or product categories run through your facility.

Solving Common 3PL Packaging Challenges
Standardizing Across Clients — A consistent mailer lineup across every client account means less training time and fewer packing errors at each station.
One Vendor, Every Client's SKU — Consolidate poly, bubble, eco, rigid, and insulated mailers into a single supplier relationship instead of managing separate vendors per client.
Scaling With Volume — Bulk case pricing and reliable stock mean you can onboard new clients or absorb seasonal spikes without a packaging bottleneck.
Custom Quotes for Multi-Client Orders — When your order spans several clients or mailer types at once, our team will build a consolidated volume quote instead of making you piece it together across separate POs.
Protecting Margins — Right-sized, right-typed mailers reduce dimensional weight and damage-related returns across every account you run.
Frequently Asked Questions
Can we get bulk or volume pricing across multiple mailer types?
Yes. Every product ships at bulk case pricing, and for larger or multi-SKU orders, contact our team for a custom volume quote across your full mailer mix — we'll send you a discount code to apply in your cart, whether you're stocking one SKU or several.
We're placing a large, recurring order across several client accounts — can you set up a standing quote?
Yes. Reach out to our team with your typical mailer mix and case volumes and we'll put together a consolidated quote, plus a discount code you can reuse in your cart for recurring orders.
Can we order different mailer types for different clients on the same PO?
Yes. Most 3PLs stock two or three MailersUSA mailer types across their client roster — for example POLYJACKET® for one client's apparel line and AIRJACKET® for another's fragile items — all under one consolidated bulk order.
Are your mailers unbranded, so we can use them across multiple client accounts?
Yes. Our standard mailers ship blank and unbranded, so the same case stock works across every client account without custom tooling or artwork minimums.
Do you offer insulated mailers for clients shipping perishables or pharma?
Yes. COOLPAC® Insulated Thermal Mailers and Box Liners maintain temperature in transit for food, perishable, and pharmaceutical client accounts.
