How to Send a Letter: The 4 Practical Ways, Compared

You have a letter that has to go out, and it's somehow been years since you last mailed anything.

There are four practical ways to send a letter in the U.S.:

• Stamp it yourself — $0.82, and minutes of your time.
• Take it to the post office counter — the same $0.82, plus a 30–60 minute trip.
• Upload a PDF — a service prints it and mails it — $2.05 for a one-page letter with Postmarkr, about two minutes.
• Print at a library or shop first, then stamp it — 15–25¢ a page, plus the errand.

Which one is right depends on what you're short on: money or time. Below: all four compared, how to address the envelope, what each really costs, how long each takes, and what to do when a letter needs proof.

The four ways to send a letter, compared#

Every route ends the same way — a First-Class letter in the USPS mailstream. What differs is the cash, the prerequisites, and your time.

Prices: USPS rates effective July 12, 2026; the Postmarkr figure is the current checkout total for one black-and-white page.

How to address and mail the envelope#

Already have the letter on paper? The whole job is four moves:

1. Delivery address — bottom center of the envelope front: name, street, then city, state, ZIP.
2. Return address — top left corner; strongly recommended, though not strictly required.
3. Stamp — upper right: one $0.82 Forever stamp covers a standard 1-ounce letter.
4. Seal it and hand it off — a blue collection box, your own mailbox with the flag up, or the counter. All three enter the same mailstream at the same speed.

Formats, business envelopes, and the edge cases live in the dedicated how to address an envelope guide.

What each way really costs#

Do it yourself. One Forever stamp — $0.82 at the rate effective July 12, 2026 — plus paper, an envelope, and ink you already own. A standard, machinable 1-ounce letter needs exactly one stamp.

The counter. A single letter costs the same $0.82 at the window as it does from your mailbox — the trip buys you supplies on the spot and a hand-off you can watch, not cheaper postage. Its real price is the 30–60 minutes of round trip.

Online. One price, $2.05, and nothing gets bolted on afterward — that number already contains the print run, the envelope, First-Class postage, the address page, and the processing fee. Extra black-and-white pages are $0.20 each. No subscription, no minimum — each piece is priced on its own.

Library or print shop first. 15–25¢ a page at the machine, then the stamp and envelope on top — a dollar and change for a short letter, plus the errand itself.

Three things push a DIY letter past that one stamp:

• Extra weight — each ounce after the first adds $0.29.
• A square or rigid envelope — picks up the $0.49 nonmachinable surcharge.
• Too thick or too big for a standard envelope — it prices as a large envelope instead: $1.69 for the first ounce.

Online, the equivalent cliff is page count: seven or more sheets ships as a flat envelope, a $2.50 surcharge. For any weight or page-count edge case, the mail cost calculator does the math.

How long each way takes#

Split the clock into three parts: your active time, what happens before USPS has the letter, and USPS transit. The third part is identical for every route — First-Class delivery runs 1–5 business days no matter how the letter entered the mailstream.

• Do it yourself: minutes of your time, and the letter is in the stream at the next pickup.
• The counter: the 30–60 minute round trip, and it's in the stream the same day.
• Online: about two minutes of your time, then production takes over — same-day processing, printing on the next business day, into the mail the day after — before USPS has it at all.
• Library or shop first: the hour-plus errand, and it's in the stream when you drop it.

Need it materially faster? Priority Mail runs 2–3 business days from $11, and Priority Mail Express 1–3 days from $35.65 with a money-back guarantee to most addresses — but both are package services priced far above a letter. For an ordinary letter, First-Class is the answer; if you're genuinely torn, here's First-Class vs Priority Mail.

What you need before you start#

Every route needs the same two things: the recipient's full address and your return address. Beyond that:

• Do it yourself: a working printer or a pen, one stamp, one envelope.
• The counter: just the finished letter — the window sells stamps and envelopes.
• Online: a PDF and the address. If the letter starts on paper, follow the iPhone and Android guide to send it from your phone. If you are drafting it digitally, export from Docs, Word, or Pages, or use the ChatGPT-to-PDF guide to format a draft. Addresses are checked before printing.
• Library or shop first: the file and a way to get there; the stamp and envelope are still on you. If no printer is the whole problem, the printer-free playbook goes deeper on that constraint.

Which way should you pick?#

• A personal note and a stamp in the drawer → just mail it. This is the one case where every service, Postmarkr included, is the long way around.
• It has to look official, run several pages, or you have no supplies → upload the PDF. Typed, clean, and out of your hands without the errand.
• Recurring business mail — invoices, notices, statements → online, as a batch. Send one letter or fifty in a single order; the price stays per piece.
• It's going abroad — a letter to Mexico, say → the post office counter. Postmarkr handles U.S. addresses only today.
• Someone may later claim it never arrived → keep reading.

When a letter needs proof#

A stamped letter leaves no record — nothing says it was ever mailed. The online route leaves a trail without you asking: your Postmarkr dashboard shows processing milestones, with USPS scan updates when available.

When the stakes are legal or financial — a demand letter, a deadline notice — the USPS tool for the job is Certified Mail: $6.37 all-in at July 2026 rates for a 1-ounce stamped letter — postage plus the certified fee — sent from the counter. The certified mail guide covers the whole lifecycle, receipts included. Postmarkr sends First-Class letters with a dashboard status trail today — certified mail is coming soon.

Whatever the letter is, the mailbox doesn't care how it got there — pick the route that costs you the least of what you're short on, money or time. If it's already a PDF, you can send it online; Postmarkr prints, addresses, stamps, and mails it.
