Committing to a single carrier means paying their price on every parcel, including the ones another carrier would have carried cheaper or faster. Mailhub compares all three on each shipment and ranks them on price, without you opening three accounts to do it.
For every parcel, Mailhub compares what each of the three would cost, then puts the best option at the top.

One account covers USPS, FedEx and DHL, with no carrier contracts to sign.
Live rates side by side on every parcel, ranked on price with the best at the top.
Buy labels in bulk and track every parcel from one dashboard, whichever carrier has it.

Multi-carrier shipping means comparing and using more than one carrier rather than sending everything with one. It matters because no carrier is cheapest or fastest on every route, size and destination. Mailhub compares USPS, FedEx and DHL on each parcel and shows every rate side by side before you commit.
No. One Mailhub account covers all three, at rates already negotiated on your behalf. You do not sign anything with the carriers and there is no volume to hit. If you already have your own carrier accounts, you can keep using them alongside Mailhub.
Mailhub ranks every carrier on price and puts the best option at the top. The final choice is yours.
