How Mail Forwarding Actually Works, and What Makes It Expensive

The phrase covers three unrelated services. Knowing which one you are buying is most of the battle.

One: the Postal Service change of address

You have moved, you file a change of address, and for a period afterwards the Postal Service redirects mail from the old address to the new one at no per-item charge. Details and the current duration are at usps.com/manage/forward.htm.

Two things about it surprise people. It is temporary, and it is a redirect rather than a fix: the sender still has your old address, and when the redirection period ends, their mail starts bouncing. Use the window to update the senders that matter rather than to avoid doing so.

It also does not do what people expect when the address you are leaving is a private mailbox. That relationship is with the store, not with the Postal Service, and the store is who has to forward the mail.

Two: hold mail

The Postal Service will hold delivery for a defined number of days while you are away and deliver the accumulated pile when you return. It is free, it is for short absences, and the current limits are at usps.com/manage/hold-mail.htm. For a two week holiday it is the right answer and nothing on this page beats it.

Three: commercial forwarding, which is what this article is about

A mailbox store or a mail service accumulates your post and ships it to wherever you are, on request or on a schedule. This is the service that costs money, and the pricing model is the thing to understand.

You are paying per shipment, not per envelope

Almost every forwarding arrangement has two components: a handling fee for the act of bundling and labelling, and postage for the resulting package. Neither scales meaningfully with the number of envelopes inside, up to a point. Thirty letters in one flat-rate envelope costs roughly what four letters in the same envelope costs.

The consequence is the single most useful piece of advice about forwarding: ask for it less often. Going from weekly to monthly cuts the number of shipments by three quarters and cuts the bill by nearly the same, because you are paying four handling fees a year instead of fifty-two. The forwarding cost estimator works this out with your own numbers, and the result is usually startling.

Weight is the other lever

Beyond the first pound or so, postage starts climbing. Weight in a mail pile is not letters, it is catalogues, magazines and the thick statement envelopes that banks still send. A pile that is half catalogues can double the cost of a forward for no benefit at all, since nobody has ever needed a catalogue urgently.

Two fixes. Ask the service to discard standard advertising mail, which most will do free or nearly free. And get the small number of genuinely important items scanned instead, so the paper never travels.

International is a different order of magnitude

Forwarding out of the United States can easily cost three or four times the domestic figure for the same weight, and it introduces customs paperwork on anything that is not obviously documents. If you are abroad long term, the strategy that works is to scan almost everything and forward once or twice a year, timed to a visit or a trusted address. Anything moving across a border that is not paper is subject to the same import rules as any other shipment, which Customs and Border Protection sets out.

What to ask before you sign up

• Is forwarding priced per piece, per shipment, or as a flat monthly fee? All three exist and they suit completely different volumes.
• Is postage at cost, or marked up? A handling fee plus actual postage is honest. A single bundled figure is fine too, as long as you can compare it.
• Will you discard advertising mail on request? This is the cheapest cost reduction available and it is often free.
• What is the cutoff? Services that ship on a fixed day mean a letter arriving on the wrong day waits a full cycle.
• What happens to parcels? Forwarding a parcel is reshipping, priced accordingly, and some services will not do it at all.

The strategy most travellers land on

Scan everything that arrives. Act on the two or three items a month that matter, from the scan. Discard the advertising. Let the rest sit. Forward once a quarter to wherever you will actually be, or never, and shred the pile at the end of the year.

That approach reduces the cost of receiving mail to the monthly service fee plus a handful of scans, which is where the economics of a mail service finally beat driving to a counter. The wider background on the practice, including how it evolved alongside long-distance work and travel, is summarised on Wikipedia's mail forwarding page.
