Frequently Asked Questions
What exactly is dimensional weight and why does it matter for holiday shipping?
Dimensional weight (DIM weight) is a billing method carriers use to account for space a package takes up versus its actual weight. If a package’s DIM weight exceeds its actual weight, carriers charge the DIM amount. During holiday season carriers enforce DIM rules strictly, so reducing package volume (by using snug mailers instead of oversized boxes) helps lower shipping costs.
Can padded mailers really protect fragile items during transit?
Yes for many small or moderately fragile items. Bubble-lined poly mailers provide good impact protection for compact goods when combined with proper internal wrapping (tissue, thin bubble wrap, or foam pouches). For very fragile, heavy, or irregular items you’ll still need a small corrugated box and shock-absorbing padding—mailers are best when the item’s shape and strength allow snug, uniform protection.
How much can I expect to save by switching from boxes to mailers?
Savings vary by carrier, package dimensions, and service level, but switching oversized boxed orders to properly sized padded mailers often reduces DIM charges because billed volume drops. The best approach is to test: weigh and measure a sample box vs. a mailer for your SKU and compare carrier pricing using current DIM divisors and published rates.
When should I choose insulated mailers over standard poly?
Choose insulated or metallized mailers when shipping temperature-sensitive items (chocolates, supplements, cosmetics, or perishables) or when extra moisture/thermal protection prevents returns. Insulated mailers add protection without the bulk of extra packing materials, but evaluate cost vs. need—don’t use thermal mailers for non-temperature-sensitive items unless their performance justifies the price.
