How to Write a Letter to Send

Writing a letter to send is easier when you know what you want the reader to understand or do. A clear structure, correct mailing details, and enough postage help your message arrive in good shape. Before you begin, decide whether you are sending a personal or formal letter and whether it needs to arrive by a particular date.

What You’ll Need

• Paper and a pen, or a document you can print
• The recipient’s full name and current mailing address
• Your return address
• An envelope large enough for the letter
• Postage appropriate for the envelope’s size, weight, and destination
• A stamp or other way to pay for postage

Step-by-Step

1. Decide the purpose. Write down the main point in one sentence. For example, you may be sharing news, making a request, thanking someone, or responding to a previous message. Keeping the purpose in view helps you avoid unrelated details.
2. Choose the right tone. For a friend or relative, a warm conversational style is usually suitable. For a workplace, organization, or unfamiliar recipient, use a polite, direct tone. If you do not know the person’s preferred title, use their full name rather than guessing.
3. Plan the key details. Note the facts the reader needs, such as relevant dates, a reference number, or what you are asking them to do. Include only details needed to understand your message. If the matter is sensitive, consider whether ordinary mail is appropriate.
4. Write the heading. Put your return address at the top left of the page, with each part on its own line. Add the date below it. In a formal letter, you can then include the recipient’s name and address. For a personal note, the recipient’s address inside the letter is optional.
5. Greet the recipient. Start with a suitable greeting, such as “Dear Jordan,” or “Hello Sam,”. Use a colon after a formal greeting if that fits your style; a comma is common for personal letters. If you are writing to a specific office but do not know a name, address the office or role clearly.
6. Write the body in short paragraphs. Begin by stating why you are writing. Add the essential context and details in the next paragraph. If you need something from the reader, explain exactly what you are asking and, when relevant, give a reasonable response date. End the body with a brief closing thought or next step.
7. Close and sign. Use a sign-off that matches the tone, such as “Sincerely,” for a formal message or “Best,” for a friendly one. Leave space and sign your name by hand if you are printing the letter. Add your typed or clearly printed name underneath so the recipient can identify you.
8. Review the letter. Check the recipient’s name, addresses, dates, spelling, and any figures or requested action. Read it aloud to catch awkward wording. Make sure the letter includes a way to contact you if a reply is expected, and remove any details you would not want others to see.
9. Prepare the envelope. Fold the letter neatly if needed. Write the recipient’s address in the center of the envelope and your return address in the upper-left corner. Put postage in the upper-right corner, unless the postal service’s instructions for your envelope specify another placement. Use the complete address format required at the destination.
10. Check postage and send it. Weigh the sealed envelope or take it to a post office or postal counter if you are unsure of the required postage. Oversized, unusually shaped, heavy, or international letters may need different postage or customs information. Drop it in an authorized collection point or hand it to postal staff. If timing or delivery confirmation matters, ask about available services before sending.

Common Mistakes

• Leaving out the return address: Without it, undeliverable mail may not be returned to you.
• Using an incomplete address: Check apartment or unit numbers, postal codes, and country details where required.
• Forgetting postage: A stamp that is insufficient for the letter’s weight or destination can delay delivery or result in extra charges.
• Burying the main point: State the reason for writing near the beginning, then provide supporting details.
• Sending without proofreading: A mistaken name, date, or address can confuse the reader or prevent delivery.
• Including private information unnecessarily: Ordinary letters can be handled by multiple people during delivery. Share only what is needed.

Tips

• Use dark, legible handwriting or print the letter for easier reading.
• Keep one main purpose per letter; use short paragraphs and plain language.
• For a formal letter, put the most important request or information near the beginning.
• Make a copy or take a photo of the signed letter if you may need to refer to it later.
• If delivery matters by a certain date, allow for postal delays and ask about tracking or other suitable services.
• For a letter involving a legal, tax, medical, or financial-planning matter, ask a qualified professional about your situation.

Troubleshooting

• You do not know the recipient’s address: Ask the recipient or a reliable contact to confirm it. Do not guess a unit number or postal code.
• You are unsure how to address the person: Use their full name and a neutral greeting. If writing to an office, name the department or role when known.
• The envelope is returned: Read the postal marking, correct the address or postage issue, and resend it. If the reason is unclear, take the envelope to postal staff for guidance.
• You sent the letter to the wrong address: Contact the postal service promptly to ask whether an intercept or correction is possible. Options vary, and a change may not be available once mail is in transit.
• The letter has not arrived: Allow for the service’s expected delivery window, then check any tracking information. If you used untracked mail, contact the recipient to confirm whether it arrived before sending a duplicate.

Frequently Asked Questions

Do I need to put the date on a letter?
It is helpful, especially for formal letters or messages the recipient may need to refer to later. Place it below your return address.

Where do I write the recipient’s address?
For a mailed letter, write it on the front of the envelope, centered and easy to read. Include the complete address in the destination’s expected format.

Should I put my address on the letter and the envelope?
For a formal letter, your address is commonly included on the page. Put your return address on the envelope so mail can be returned if delivery fails.

How much postage does a letter need?
It depends on the destination, weight, dimensions, and postal service rules. Check current postal guidance or have the envelope weighed before sending.

Can I send a handwritten letter?
Yes. Use clear handwriting and dark ink, and leave enough space between lines. Printing may be easier for a long or formal letter.

Should I use tracked or registered mail?
Consider a service with tracking or delivery confirmation when you need evidence of mailing or delivery. Ask postal staff which option fits your needs and the destination.
