What we respond to

• Corrections and updates: If you spot an outdated divisor, an incorrect formula, or a stale carrier policy, please tell us. We update reference data regularly and credit corrections where useful.
• Carrier suggestions: If there's a major carrier we're missing — particularly regional or country-specific carriers — let us know which one and we'll evaluate adding it.
• Article ideas: Topics you wish were covered, questions you can't find answers to elsewhere, or specific shipping scenarios you'd like analyzed.
• Partnership inquiries: Affiliate programs, carrier-supplied rate APIs, integration opportunities, or content collaboration.
• Privacy and data requests: GDPR, CCPA, or other regional privacy law requests. See our privacy policy for what we collect.
• Bugs and feedback on the calculator: Anything that doesn't work as expected, displays incorrectly, or gives results you can't reconcile.

What we don't help with

• Specific shipping rate quotes: We calculate dimensional weight, not actual shipping costs. For real quotes, use the official rate calculators on each carrier's website (linked from every carrier page).
• Disputed carrier charges: If your carrier billed you incorrectly, contact them directly. We can help you understand whether DIM weight was applied correctly, but we can't issue refunds or adjust invoices.
• Account-specific negotiated rates: If you have a custom contract with a carrier, your divisor and rates may differ from published values. We can only reference published rates.

Response times

We aim to respond to corrections and bug reports within 2-3 business days. Partnership and editorial inquiries may take longer (up to 1 week). Privacy requests are handled within the timeframes required by applicable law.
