Mack Weldon customers commonly need help with an order that cannot be changed, a delayed or missing shipment, sizing, a return or exchange, the Try On Guarantee, a defective product, rewards points, a digital gift card, or account access.

Mack Weldon Customer Service Versus the Corporate Office
MackWeldon.com is operated by Mack Weldon, Inc.
Mack Weldon, Inc.
1201 Broadway, Suite 600
New York, NY 10001
The New York address is used for company, privacy, and accessibility correspondence. It is not an automatic merchandise-return address, fulfillment center, or guaranteed walk-in customer-service location.
Do not mail clothing, underwear, footwear, accessories, gift returns, or defective merchandise to the corporate address. Start the return or claim through the online portal and use the destination printed on the authorized label.
Mack Weldon does not currently publish a separate corporate switchboard. Its text-support number should not be labeled as a corporate telephone number.
Can a Mack Weldon Order Be Changed or Canceled?
Mack Weldon uses an automated fulfillment process, so the opportunity to change or cancel an order is extremely limited.
Contact support immediately when:
- The wrong size or color was ordered
- The quantity is incorrect
- The shipping address is wrong
- A duplicate order may have been submitted
- The order should be canceled
Do not assume that a requested change will be completed. Once tracking has been issued, Mack Weldon generally cannot change the shipping address or edit the order. The customer may need to receive the package and use the return or exchange process.
Changing an address in the online account updates future orders but does not automatically alter an order already submitted.
Mack Weldon Shipping and Tracking
Mack Weldon ships within the United States, including eligible APO, FPO, and DPO addresses, and also offers international shipping to supported countries.
Shipping prices and free-shipping thresholds depend on:
- The order value
- The selected delivery speed
- The destination
- The customer’s Mack Weldon Rewards tier
- Current promotions
Review the shipping price and estimated delivery time during checkout because published thresholds and promotions can change.
Most orders are expected to ship within one or two business days. Orders submitted late on Friday or during a weekend may not be processed until the following business day.
A shipping-confirmation email should include the carrier and tracking number. Carrier scans can be delayed, and estimated arrival dates are not guarantees.
Missing, Stolen, or Delayed Packages
If tracking has not updated for several days:
- Open the tracking link on the carrier’s own website.
- Confirm that the delivery address is correct.
- Check with household members, neighbors, front desks, mailrooms, and building staff.
- Look for a delivery photograph or location note.
- Contact Mack Weldon with the original shipping address and tracking number.
Customers who purchase Checkout+ receive package protection for qualifying lost or stolen shipments. Claims remain subject to the applicable program requirements and may be denied when fraud or abuse is suspected.
Customers who did not purchase package protection should still contact Mack Weldon and the carrier, but replacement or reimbursement is not automatically guaranteed.
Mack Weldon Return and Exchange Policy
Mack Weldon accepts qualifying returns within 30 days of purchase.
To qualify for a standard return:
- The product must be unworn.
- The product must be unwashed.
- Original tags and packaging should be retained.
- Underwear must remain in its original packaging.
- The product cannot be marked final sale.
- The request must be submitted during the return period.
Start through the Returns Portal using the order number and shipping ZIP code. Available options may include an exchange, refund, or Mack Weldon credit.
Mack Weldon may deny a return or exchange when it finds evidence of fraud, abuse, or manipulative conduct.
Checkout+ Return Coverage
Checkout+ is an optional service offered during checkout.
For qualifying orders, Checkout+ can include:
- Covered return labels
- Free exchanges
- Package protection for loss or theft in transit
A customer who declines Checkout+ may still return qualifying merchandise but is generally responsible for the cost of the return-shipping label.
Checkout+ does not override the standard return conditions. Final-sale merchandise and other ineligible products remain excluded.
Mack Weldon Try On Guarantee
The Try On Guarantee allows a first-time customer to try one eligible pair of underwear and request a refund or exchange without sending that pair back.
To use the guarantee:
- Open the Returns Portal.
- Enter the order number and shipping ZIP code.
- Select the one pair of underwear involved.
- Choose the refund or size-exchange option.
- Complete the requested explanation and confirmation.
The guarantee:
- Applies to one pair only
- Must be requested within 30 days of receipt
- Does not require the eligible pair to be returned
- Does not apply to final-sale products
- Does not include long underwear, long johns, or running tights
- Does not normally refund original shipping on a single-item order
- Can generally be used only once by a customer
If several pairs were purchased, try and wash only one pair first. The unopened pairs may remain eligible for an ordinary return or exchange.
Gift Returns
A gift recipient can begin a return without automatically notifying the person who placed the order.
Gift returns are generally eligible for:
- An exchange
- Internal Mack Weldon credit
The gift recipient does not normally receive a cash refund to a different payment method.
The Returns Portal may require the original order number, purchaser information, or delivery details. Contact support when the original order information is unavailable.
Refund Processing
Mack Weldon issues a refund after the returned merchandise reaches the designated facility and passes inspection.
The time needed for the credit to appear can depend on:
- Return transit time
- Warehouse inspection
- The original payment method
- The customer’s bank or payment provider
Keep the return receipt and tracking number until the refund is complete. Contact support if tracking shows delivery but no refund or status update appears after a reasonable processing period.
International refunds may require approximately seven to ten business days after the return is received and inspected.
Damaged, Defective, Incorrect, or Missing Products
For a damaged or defective domestic order, use the online claim process. International customers should contact email or chat support.
Include:
- The order number
- The product name and size
- Photographs of the product
- Photographs of damaged packaging
- A photograph of the packing slip when relevant
- A description of the requested replacement, refund, or exchange
If an item listed on the packing slip is missing, Mack Weldon may send the item if inventory remains available or issue a refund when it is sold out.
If another customer’s order or invoice was received, do not publish that person’s information. Contact Mack Weldon privately.
Mack Weldon Product Warranty
Mack Weldon publishes a one-year warranty for products that have been subjected to reasonable use.
A warranty request may depend on:
- The purchase date
- The nature of the defect
- Whether the care instructions were followed
- Normal wear versus premature failure
- Photographs of the problem
- Proof of purchase
The warranty is not necessarily a promise that every worn, stained, stretched, damaged, or altered product will be replaced. Contact support and request a written decision.
Mack Weldon Rewards
Mack Weldon Rewards is a free loyalty program. Members can earn points through qualifying purchases and other eligible activities and redeem the points for discounts or products.
- Points expire after one year without account activity.
- Activated rewards do not currently expire.
- Points earned from a returned purchase are deducted.
- Purchases made with gift cards or store credit may not earn points on that portion of the payment.
- An email address is required to use and redeem program benefits.
If an eligible activity has not produced points after five business days, contact hello@mackweldon.com.
Save screenshots of the points balance, reward offer, purchase, and account activity when reporting a discrepancy.
Mack Weldon Digital Gift Cards
Mack Weldon currently offers digital gift cards rather than physical cards.
- Digital gift cards do not expire.
- An unused balance remains available for a future purchase.
- The recipient can use the card online.
- The purchaser may print the digital card rather than emailing it.
Do not publish or forward the gift-card code to an unintended person. Anyone who obtains the code may be able to use the balance.
Contact support when a gift card is not received, cannot be redeemed, or shows the wrong balance.
Mack Weldon Account and Login Help
Mack Weldon currently uses passwordless account login.
- Select Account or Log In.
- Enter the email address associated with the account.
- Wait for the four-digit login code.
- Check spam or junk folders if it does not arrive.
- Enter the code only on MackWeldon.com.
Do not provide the code to an unsolicited caller, texter, social-media account, or person claiming to verify an order.
The account can display prior orders, tracking, returns, rewards activity, saved addresses, and reordering options.
Payment Problems and Duplicate Authorizations
A failed checkout can temporarily produce more than one pending authorization. A pending authorization is not always a completed charge and may disappear automatically after the bank releases it.
If a charge appears unfamiliar or duplicated:
- Review order-confirmation emails.
- Check whether more than one order was completed.
- Review the Mack Weldon account history.
- Contact Mack Weldon with the general date and amount.
- Contact the card issuer if the charge is unauthorized or remains unresolved.
Do not send Mack Weldon or CustomerServiceNumbers.com a complete card number or security code.
International Orders and Returns
Mack Weldon ships to supported international destinations. Available currencies, delivery times, duties, taxes, and return charges depend on the destination.
International returns must generally be:
- Unworn
- Unwashed
- In original condition
- Returned with tags
- Not marked final sale
A prepaid international label may have a return fee deducted from the refund. Customers choosing self-postage are responsible for shipping, reverse duties, taxes, and tracking.
International return labels may expire if they are not used promptly.
Product Sizing and Care
Use the Size Guide and the Size and Fit section on the individual product page before ordering.
Follow the care instructions printed on the product. Many Mack Weldon products recommend cold washing and low-heat drying, but fabrics and collections differ.
Cotton-rich products may shrink when exposed to excessive heat. Failure to follow care instructions can affect return and warranty eligibility.
