About Mailhub
Mailhub is multi-carrier shipping software that helps ecommerce businesses compare shipment costs before they commit. It gives users access to pre-negotiated USPS, FedEx, and DHL rates from the first label, with no carrier account, contract, or minimum volume required. Rates appear on one screen and are ranked by price, with the lowest-cost option shown first while the shipper makes the final choice. Addresses are validated at label purchase to help avoid correction fees. Shopify orders sync with one dashboard, while other stores or internal systems can connect through the Mailhub Shipping API. Teams can print up to 50 labels at a time, buy and cancel labels as plans change, and let AI agents quote and book shipments through MCP. Mailhub has no subscription charge and bills shipments separately; custom rates are available for higher-volume shippers.
