Your executive has signed the letter, it has to go out today, and the post office is a drive you don't have time for. You have more options than the counter line, and they split on one question: is the letter already printed, signed and stamped?
If it is, your own mailbox or a blue USPS collection box will take it. If it's still a PDF in your inbox, a print-and-mail service removes the printer, the stamp and the trip together. Click-N-Ship can sell you postage, including for First-Class letters, but you still prepare the physical letter yourself. Free Package Pickup has separate eligibility rules.
Below, each option is judged on what you need, whether you leave the house, what record you get and what it costs. If you mail for an executive every week, our page for executive assistants covers the whole routine.
Every option at a glance#
Option | What you need on hand | Leave the house? | How you know it was mailed | Rough cost |
|---|---|---|---|---|
Stamps + your own mailbox | Printed, signed letter; envelope; stamp | No | You don't. First-Class letters have no tracking | $0.82 Forever stamp, up to 1 oz |
Stamps + blue collection box | Same | To the box, not a counter | Same | $0.82 |
Click-N-Ship + free Package Pickup | Printed document in a Priority Mail Flat Rate Envelope; a printer for the label | No | USPS Tracking | $11.97 online (USPS holiday price through Jan. 16, 2027) |
FedEx Office | A PDF to print there; then a stamp, or a FedEx shipment | Yes | A stamp: nothing. FedEx: a tracking number | Printing plus postage, or a FedEx shipment quote |
Errand runner | A finished, stamped envelope | No (they go) | Whatever they send back | The runner's fee plus postage |
Upload a PDF to a print-and-mail service | The signed PDF, the addresses, a card | No | Depends on the service | Varies by service; Postmarkr $2.05 |
Prices are for a one-page, one-ounce letter, read from each provider's site on October 13, 2026.
Already printed and stamped? Your mailbox or a blue box is enough#
You can mail a letter from home with nothing but a stamp. USPS lists three ways that skip the counter: put it in your mailbox and raise the flag, use the outgoing slot of a cluster mailbox, or drop it in a blue collection box. Three things decide whether that works.
Weight. One Forever stamp ($0.82) covers 1 oz, which USPS puts at about four sheets of printer paper in a business-size envelope. A signed six-page agreement is over that. Each extra ounce adds $0.29, up to 3.5 oz, and you can combine stamps to make up the total; two Forever stamps cover 2 oz, overpaying by 53 cents. Square, rigid or lumpy envelopes, or ones with clasps, cost $0.49 more. The full cost of mailing a letter covers every weight.
The 10-ounce, half-inch line. Mail carrying only stamps that weighs more than 10 oz or is more than half an inch thick can't go in a collection box or out with your carrier. USPS requires you to hand it to an employee at a Post Office, so a stamped board packet is a counter trip.
Timing. Every blue box has its collection times posted on it. A letter dropped after the last pickup isn't collected until the next postal business day.
What you won't get is a record. First-Class letters have no tracking, and a letter left in a box or your mailbox is postmarked at a processing plant; USPS says that date "will not necessarily match" the day you dropped it off.
Keep stamps ready for the next letter#
Keep a book of stamps in the desk drawer so the next letter is ready to go (do Forever stamps expire?).
Not printed yet? Upload the PDF to a print-and-mail service#
If the letter is a PDF (signed in DocuSign, on an iPad, or on paper and scanned), a print-and-mail service is the most direct way to send a physical letter from your computer: it skips the printer, the envelope, the stamp and the trip. It prints what's on the page, so the signature has to be on the PDF before you upload. Our guide to mailing a letter without a printer covers the upload step and how to make sure the PDF prints right.
Where Postmarkr fits
Upload the signed PDF and you see the preview and the exact total before you pay. We print it the next business day, put it behind an address page in a window envelope and mail it USPS First-Class; USPS estimates 1–5 days for delivery. You keep the production PDF once it is available and a status page with processing milestones, plus USPS scan updates when available. We email you when you pay and when it's sent to print. Up to 10 different letters fit in one checkout, each to its own address. If USPS confirms a letter was lost, we'll resend it for free. See how assistants use it.
What it doesn't do: Certified Mail, a Certificate of Mailing or a USPS-confirmed mailing date; packages or FedEx; addresses outside the US; signing for anyone.
Click-N-Ship buys postage; Package Pickup has separate rules#
Buying postage online and arranging a pickup are separate tasks. Neither prints or signs the letter's contents for you.
- Click-N-Ship supports First-Class letters and envelopes as well as package services. USPS's label-creation guide includes a First-Class Mail Letter or Envelope option; you enter its weight and dimensions and prepare the physical letter yourself. First-Class letters and large envelopes aren't eligible for Label Broker printing. For eligible shipping labels, Label Delivery costs $1.65 per label; don't assume that option is available for every service.
- Package Pickup is free for Priority Mail Express, Priority Mail, Ground Advantage, returns and international packages. First-Class Mail is picked up only alongside one of those, and stamp-only items over 10 oz or half an inch aren't eligible.
If a document is urgent and you want tracking, put it in a Priority Mail Flat Rate Envelope, buy the label on Click-N-Ship for $11.97 (it's $13.90 at the counter; both are USPS holiday prices through January 16, 2027) and schedule a free pickup. USPS lists Priority Mail at 2–3 days with USPS Tracking included. You still need the document printed and signed, the envelope (free to order from USPS ahead of time) and a printer for the label.
For an ordinary stamped letter there's nothing to schedule. Raise the flag.
FedEx Office: a printer down the street, not a post office#
FedEx Office solves the printer, not the trip. You can send a PDF to a store and print it there; the steps and per-page prices are in our guide to mailing a letter without a printer. A FedEx Office isn't a post office, so the printed letter still needs a stamp and a USPS mailbox.
Or send it as a FedEx shipment. Ask for the price and delivery commitment for the service and destination before choosing it. That is a separate shipment, rather than a stamped USPS letter, and you still need to get the document to the store.
An errand runner: someone else makes the trip#
Paying someone to make the run takes it off your day. Boldly, which places remote executive assistants, suggests apps like Taskrabbit for farming out in-office jobs like this one. Ask the runner for their fee and agree what the trip includes before booking.
Two things to agree first. The runner needs a finished envelope, so someone still prints, signs and stuffs it. Ask what they will bring back: a photo of a drop-off is different from a USPS receipt. If you need a dated counter receipt and cannot get there, ask them to take the letter to the counter and return that receipt.
When the mailing needs a dated receipt or a counter handoff#
If a contract or deadline calls for a particular service or a dated USPS record, choose that route before skipping the counter:
- A dated postmark. Ask for a manual (local) postmark when you hand the letter over; USPS applies it free of charge. How to postmark a letter covers what to ask for.
- A Certificate of Mailing, USPS's proof of the date it accepted the letter, bought at the time of mailing.
- Certified Mail. Ask for a postmarked sender receipt at a Post Office counter if you need that record. Certified Mail itself can also be prepared through a provider; it is not inherently a counter-only service. Certified Mail alternatives explains when something else will do.
- Stamped mail over 10 oz or half an inch.
For an ordinary thank-you letter, vendor letter or year-end note, choose by whether the letter is already printed and by the collection or processing schedule. An upload starts a print-and-mail workflow; it does not promise mailing today.
Questions people ask#
Does the mail carrier pick up outgoing mail from my mailbox?#
Yes. Put the stamped letter in your mailbox and raise the flag, or use the outgoing slot of a cluster mailbox. Stamp-only mail over 10 oz or half an inch thick has to go to a Post Office counter instead.
Can you use Click-N-Ship for letters?#
Yes. USPS's current Click-N-Ship guide includes First-Class letters and envelopes. It sells the postage; you still print and sign the letter, prepare the envelope and meet its size and weight limits. Buying that postage does not make a lone First-Class letter eligible for free scheduled Package Pickup.
How long does the letter take once it's mailed?#
USPS estimates 1–5 days for First-Class Mail, from when USPS has the letter. First-Class Mail delivery time has the detail.
