Mailing a letter for the first time takes five steps: fold the letter into the envelope and seal it, write the recipient's address in the center and your return address in the top-left, put a stamp in the top-right corner, and drop it in a mailbox or at the post office.
| Step | What to do | The detail that matters |
|---|---|---|
| 1. Fold and insert | Fold a standard page into thirds and slide it into the envelope | Fold the bottom third up first, then the top third down, so the letter unfolds top-down when opened |
| 2. Seal | Moisten the envelope flap and press it shut | Seal the full length of the flap; a half-sealed envelope can jam sorting machines and tear open |
| 3. Address | Recipient in the center, your return address top-left | Print clearly in dark ink; block capitals beat cursive for machine reading |
| 4. Stamp | One stamp in the top-right corner | The top-right position is where automated equipment looks for postage |
| 5. Send | Mailbox, blue collection box, or post office counter | Check the pickup time posted on the box; after it, your letter waits for the next collection |
Four things: the letter itself, a standard envelope (the common #10 business envelope fits a folded 8.5x11in page), a stamp for a standard letter, and the recipient's full address including the ZIP or postal code. Stamps are sold at post offices, many grocery and drug stores, and online; you don't need to visit a post office just to buy one. If the letter is unusually heavy, thick, or rigid, take it to the counter instead of guessing: extra postage is cheaper than a returned letter.
Write the addresses before you seal the envelope, while it's flat on the table: it's much easier to write neatly on a flat surface. The recipient's name and address go in the center of the envelope, your return address in the top-left corner. The return address is your safety net: if the letter can't be delivered, it comes back to you instead of vanishing.
You have three options. Your own mailbox works if it has a flag: put the letter inside, raise the flag, and the carrier collects it on the route. The blue collection boxes on street corners work any time, and each one has the daily pickup time printed on it; drop your letter before that time and it enters the system the same day. The post office counter works when you want a person to check the postage or you need a service like certified mail.
Two beginner mistakes to avoid. First, don't drop a letter in a collection box after the last posted pickup if it's urgent: it sits there until the next business day's collection. Second, don't put the stamp anywhere but the top-right corner. The placement isn't tradition; it's functional. Automated equipment photographs the top-right corner to verify postage, and a stamp in the wrong spot can be missed, which delays your letter or sends it back.
For an ordinary letter, you don't get confirmation: it just arrives in a few days. If you need to know, the post office sells tracking add-ons at the counter, or you can send the letter certified (US) or registered (Canada) for a delivery record. If the letter comes back to you with a yellow sticker, read the sticker: it explains why delivery failed, usually a bad address or missing apartment number. Fix it and re-mail.
And if you'd rather skip the envelope, the stamp, and the trip entirely: you can have a letter printed and mailed for you. With LetterAgent, you describe the letter to your AI assistant, approve the exact quoted price, and it's printed and mailed with first-class postage. No printer, no stamps, no post office visit.
