To send mail in the USA, you have two main options: the traditional USPS route or an online mailing service. Both deliver through the USPS network, but they differ a lot in convenience and effort.

After helping thousands of Americans send mail through PostPal, we've noticed most people pick a method based on one factor: how much time they have. If you have stamps on hand and don't mind a quick trip to the mailbox, traditional mail works. If you'd rather skip the post office entirely, online mailing is faster.

To send a letter through USPS, you need to prepare your letter, address your envelope correctly, apply postage, and drop it at a mailbox or post office. Here's the step-by-step process:

Step 1: Gather Your Supplies

• Paper and envelope (a standard #10 business envelope works for most letters)
• Postage stamps (available at USPS locations, CVS, Walgreens, most grocery stores, and usps.com)
• Pen for addressing

Step 2: Write and Prepare Your Letter

• Write or print your letter
• Fold it to fit your envelope (typically tri-fold for standard 8.5" x 11" paper)
• Place in envelope and seal

Step 3: Address Your Envelope Correctly

This is where most mistakes happen. Write the recipient's address in the center:

• Full name on line 1
• Street address (with unit/apt number) on line 2
• City, State ZIP on line 3 (e.g., SPRINGFIELD IL 62701)

Add your return address in the top-left corner using the same format. USPS recommends ALL CAPS for better OCR scanning, but it's not required.

Step 4: Apply Postage

Place your stamp in the top-right corner. For a standard letter (under 1 oz) within the US, one Forever Stamp (around $0.73 in 2026) does the job.

Step 5: Mail Your Letter

Drop your letter in any blue USPS collection box, hand it to your mail carrier, or take it to a post office. Your letter will typically arrive in 1-5 business days.

Step 4: Preview and Pay

Step 5: Done — We Handle the Rest

Your letter is printed and mailed within 24 hours. It arrives via regular USPS delivery in 1-5 business days domestically.

The whole process takes under 5 minutes, and you never leave your computer.

Sending mail in the USA costs anywhere from $0.73 to $10+ depending on your method and destination. Here's the breakdown:

USPS Stamp Prices (2026)

• Domestic Forever Stamp (1 oz letter): around $0.73
• Postcard stamp: around $0.56
• Global Forever Stamp (international 1 oz letter): a flat international rate
• Certified Mail with Return Receipt: several dollars on top of regular postage

Note: These prices are postage only. You also need envelopes, paper, and to factor in the time and gas to reach a mailbox.

PostPal Pricing

• Domestic (within the US): $5 flat
• International (worldwide): $10 flat

PostPal's price includes printing, envelope, postage, and handling. Once you add up supplies and your time, online mailing often comes out at a similar real cost — see our full DIY vs PostPal cost comparison.

Mail in the USA typically takes 1-5 business days for domestic First-Class delivery and 7-14 business days internationally, though international varies widely by country.

USPS Delivery Estimates

• Within same city: 1-2 business days
• Within same state: 1-3 business days
• Across the US: 3-5 business days
• Priority Mail (domestic): 1-3 business days
• International First-Class: 7-14 business days (varies by country)

These times apply whether you mail it yourself or use an online service — the letter travels through the same USPS network either way.

The most common mistakes when sending mail in the USA are addressing errors that delay or stop delivery. Here's what to avoid:

Address Formatting Errors

• Wrong ZIP code: Use the correct 5-digit ZIP — or better yet, ZIP+4 (e.g., 90210-1234) for OCR accuracy
• Missing apartment/unit number: If your recipient lives in an apartment or condo, include the unit number on the same line as the street
• Illegible handwriting: USPS uses automated sorting machines that struggle with poor handwriting
• Skipping the state abbreviation: Always use the standard two-letter abbreviation (e.g., CA, NY, TX)

Postage Mistakes

• Insufficient postage: Letters over 1 oz need extra postage
• Wrong stamp type: Using a domestic stamp for international mail (use a Global Forever Stamp instead)
• Stamps falling off: Make sure stamps are firmly attached

Envelope Issues

• Envelope too small: Cramped addresses are hard for OCR to read
• Bulky contents: Thick or rigid items may need extra postage or a different mail class

Online mailing services eliminate most of these errors with printed addresses and validated postage.

Can I send mail without stamps?

No — all mail sent through USPS requires postage. If you use an online mailing service like PostPal, postage is included in the price and applied for you.

Where can I buy stamps in the USA?

You can buy stamps at USPS locations, CVS, Walgreens, most grocery stores (Kroger, Safeway, Publix), Walmart, Costco, and online at usps.com.

Can I send mail from my apartment mailbox?

You can put outgoing mail in your apartment's outgoing slot if it has one. Many buildings have one. Otherwise, raise the red flag on a curbside box, drop it in a blue USPS collection box, or visit a post office.

Do I need a return address on my letter?

A return address isn't legally required, but it's strongly recommended. Without one, undeliverable mail can't come back to you.

Can I send mail on weekends?

You can drop mail in a blue collection box anytime, but USPS doesn't deliver on Sundays (with the exception of some Amazon and Priority packages). Saturday delivery is standard for First-Class Mail. Online mailing services accept orders 24/7, though printing and mailing happen on business days.

How do I send a letter internationally from the USA?

Use the same process as domestic mail, but apply a Global Forever Stamp and write the destination country in capital letters as the last line of the address. Or use PostPal's $10 international rate to skip the guesswork.

What's the cheapest way to send mail in the USA?

The cheapest postage is a single Forever Stamp (around $0.73) for a 1 oz letter. Once you factor in envelopes, paper, and your time, online services like PostPal often come out at similar value with much more convenience.

Can I track my letter?

Standard First-Class lettermail isn't tracked. For tracking, upgrade to Certified Mail, Priority Mail, or Priority Mail Express, which cost more but include a tracking number and (for Certified) signature on delivery.

Sending mail in the USA is straightforward once you know your options. If you have stamps and supplies on hand, traditional USPS works fine. If you'd rather skip the trip to the post office and have your letter professionally printed, an online service like PostPal handles everything for a flat $5.

Either way, your letter travels through USPS's network and lands in 1-5 business days domestically.
