What we can help with

We review every message. Common topics include inaccurate carrier rates, requests for new calculators, questions about how a calculation works, and feedback on the tools. If you found a rate that looks wrong, please include the origin ZIP code, destination ZIP code, weight, and dimensions so we can investigate quickly.

For partnership or embed inquiries, see the embed calculators page. For general shipping questions not related to the site, your carrier is the best resource since we do not have access to account-level details or live shipment tracking.

What to expect

We typically respond within one to two business days. If your message is about a rate discrepancy, we may need a day or two to pull the relevant carrier data and verify the calculation before responding. We do not share contact information with third parties and will only use your email to reply to your message.

We are not affiliated with UPS, FedEx, USPS, or DHL.

We recommend using these tools for planning and budgeting, and always confirming final costs with your carrier before shipping.
