Thank-you Note Mailing Etiquette

After you’ve written your perfect thank-you note, take the same care in mailing it promptly.

It is considered proper etiquette to send the thank you note within a few days of receiving the gift or kind gesture. Read more etiquette tips.

The final touches are important; address the card legibly and carefully (spell their name(s) correctly!) and write the address on the centre of the card.

Handwritten thank-you notes are the most personal and appropriate way to show your appreciation. If you also send an email thank-you note, remember that the digital version of a thank-you note should still be thoughtful and heartfelt.

How to Address a Thank-You Letter Envelope: A Comprehensive Guide

When addressing the envelope of your thank-you note, it is important to make sure the recipient’s name and address are written correctly.

This guide will provide you with tips and advice on how to properly address an envelope so that your mail will get to where it needs to go.

address the envelope with the delivery address in the center of the envelope, and the return address (yours) in the top left corner.

Formatting the Recipient Address

The first step in addressing an envelope is formatting the address. Preferably the address should be written in all capital letters, usually in a non-cursive font, and should include the recipient’s name on the first line. Use a black or blue pen.

Keep in mind that the mail sorting machines read the address from the bottom up, so format the address in a predictable way to avoid delaying delivery.

Address Abbreviations

When writing out the address, it is important to use the correct abbreviations to save space. Common abbreviations:

Addressing Women

Addressing Couples

Addressing a Family

When addressing an envelope to an entire family, it is best to use the masculine form of the family name, i.e. Mr. and Mrs. Jones.

Addressing a Person with a Courtesy Title

When addressing an envelope to a person with a courtesy title, such as a doctor or reverend, use the title and the person’s full name. For example, if the person’s name is Dr. John Smith, the envelope should be addressed to Dr. John Smith.

Addressing the Military

When addressing an envelope for someone who is in the military, use the following format:

Rank Name 
Unit and Box Number 
APO/FPO/DPO (Air/Fleet Post Office/Diplomatic Post Office) 
City, State, ZIP Code 

Addressing a Business

When addressing an envelope to a business, use the company’s full name and include the department, if applicable. If the business has a suite or floor number, include that as well.

Addressing an Envelope to Multiple People

When addressing an envelope to multiple people, list each person’s name on a separate line.

Family: When addressing an envelope to multiple recipients with the same last name at the same address, the first line should read the family name, such as ‘The Family of Mr. and Mrs. John Doe’ or ‘The Doe Family.’ This informs the recipients that the mail is intended for everyone belonging to that family.

You could also write “To the residents at [address]”.

Business: If the recipients are part of a business, you can replace ‘residents’ with the appropriate titles, such as ’employees,’ ‘supervisors,’ or ‘owners’ of the listed address. If there are not too many recipients, you can list their names on a single line. For example, ‘Mr. John Doe, Mrs. Jane Smith, Ms. Mary Mack, Mr. Jack Black.’

If there are more than will fit on one line, continue on an equally aligned second line without using the word ‘and.’ If there are still more, it is best to refer back to writing a more general group name such as ‘The Family of…’ or ‘The Doe Family’ or ‘The [Business Name] Family’

Addressing the Return Envelope

When addressing a return envelope, use the same address format as you used for the main envelope. Be sure to include the proper postage and a return address in the top left corner on the front of the envelope.

Addressing International Mail

If the envelope is being sent internationally, it is important to include the country name in the address. Additionally, be sure to check with the destination country for any additional requirements for international mail.

By following these tips and advice, you can be sure that your mail will reach its destination safely and quickly. With a little bit of attention to detail, you can make sure your mail gets to where it needs to go.

Choosing the Right Postage

The amount of postage you need depends on the weight of the envelope. You can use a postage calculator to determine the right amount of postage for your thank-you note, or mail it from a post office and the clerk will apply the proper postage. Usually, the letter will require just one letter-mail stamp if sent domestically.

Sending Your Thank-You Note

Check things over: make sure the envelope is sealed properly, and that the address is written clearly and legibly. You should also make sure that you have included a return address on the envelope (usually in the top left corner) in case the thank you note needs to be returned.

By following these steps, you can make sure that your thank-you note is properly addressed, mailed, and received. Writing a thank-you note is a great way to show your appreciation and let someone know that you are grateful for their kindness.

Once you have addressed the envelope and chosen the right postage, you can send your thank-you note with an appreciative heart. And away it goes!
