And people love real mail.
A letter is the follow-up that doesn’t get archived.
60% of Americans say a card or letter in the mail means more to them than an email, according to a 2020 U.S. Postal Service survey.
U.S. Postal Service, 2020 [2]
Advertising mail from a business people already know gets read 64% of the time, according to the U.S. Postal Service’s 2025 Household Mail Survey. A thank-you letter is more personal still.

People who write thank-you letters underestimate how surprised and happy the recipient will be, and overestimate how awkward it will feel, according to research by Amit Kumar and Nicholas Epley in Psychological Science.

Close the deal. Keep the client.
The keys are handed over, the clients are hugging in the driveway, and you’re already late for the next showing. The thank-you you meant to send? Type it on your phone in the car. It’s printed on your own letterhead, with your logo and footer, and mailed for you.
Then send another on the home anniversary. A letter won’t win the referral; your work did that. It just makes sure your name is the one they remember when a friend asks who they used.
Letters agents send.
The closing thank-you
The one they keep with the keys.
The referral thank-you
For the friend who sent you a buyer, whether or not it closed.
The home anniversary
One year in. A check-in that isn’t a pitch.
Just sold, just listed
A real letter to the neighbors, on your letterhead.
The open-house follow-up
For the couple who stayed and asked about schools.
The whole sphere
One letter, every client, each copy personal: $3 a letter, $2.50 from 10 and $2 from 50.
Good to know.
