Do poly mailers cost more to mail

In general, poly mailers can cost more to mail than traditional envelopes or boxes, but the exact cost difference depends on several factors, including:

1. Weight and size: Poly mailers are often larger and heavier than traditional envelopes, which can increase the postage cost.
2. Material and thickness: Thicker, higher-quality poly mailers may be more expensive to mail than thinner, lower-cost options.
3. Destination: The cost of mailing poly mailers can vary depending on the destination, with longer distances or heavier packages costing more.
4. Shipping carrier: Different carriers, such as USPS, UPS, or FedEx, may have different rates for poly mailers.
5. Package dimensions: The dimensions of the poly mailer, including its length, width, and height, can affect the postage cost.

Here are some general estimates of the cost difference between poly mailers and traditional envelopes:

• USPS:
  • Small poly mailers (up to 6" x 9" x 1"): 10-20% more expensive than a standard letter envelope
  • Medium poly mailers (6" x 9" x 2" to 12" x 15" x 2"): 20-40% more expensive than a standard flat rate envelope
  • Large poly mailers (over 12" x 15" x 2"): 40-60% more expensive than a standard flat rate box
• UPS:
  • Small poly mailers (up to 6" x 9" x 1"): 15-30% more expensive than a standard envelope
  • Medium poly mailers (6" x 9" x 2" to 12" x 15" x 2"): 30-50% more expensive than a standard box
  • Large poly mailers (over 12" x 15" x 2"): 50-70% more expensive than a standard box
• FedEx:
  • Small poly mailers (up to 6" x 9" x 1"): 20-40% more expensive than a standard envelope
  • Medium poly mailers (6" x 9" x 2" to 12" x 15" x 2"): 40-60% more expensive than a standard box
  • Large poly mailers (over 12" x 15" x 2"): 60-80% more expensive than a standard box

Keep in mind that these are rough estimates, and the actual cost difference will depend on your specific shipping needs and carrier choices. It's always a good idea to check with your carrier for the most up-to-date rates and to compare prices across different carriers.
