Send a letter to your grandparents online
Grandparents still love opening real mail. Type a letter on your phone or laptop, attach a photo or two, and we print and mail it through USPS. No printer, no envelope, no trip to the post office.
How it works
Four steps. Most letters take under two minutes from sign-in to mailed.
- 1
Write your letter on your phone
Type directly in our editor. Add line breaks, basic formatting, and a closing.
- 2
Attach a photo (optional)
Upload one or two recent photos. We print them on the same paper as the letter.
- 3
Enter the address
Add your grandparents' home, retirement community, or care facility address.
- 4
We mail within 24 hours
Letter is printed, sealed, stamped, and mailed via USPS. You receive a confirmation.
Who this is for
- Grandchildren who do not own a printer
- Adults living far from their grandparents
- Parents helping kids write letters to grandparents
- Anyone overseas who wants to send mail back to the US

Frequently asked questions
Can I include a photo in the letter?
Yes. Upload one or more photos and we print them with the letter. Photos print on standard paper as part of the letter — they are not separate prints.
Can my child write the letter?
Yes. You can type a child's words on their behalf, or upload a PDF of a hand-drawn picture or written letter to be mailed exactly as drawn.
Can I mail to a retirement community or assisted living facility?
Yes. Use the recipient's name on the first line and the facility's address. Some facilities like the recipient's room number or unit on its own line — check with the facility if unsure.
Can I send a letter from outside the US?
Yes. Many Americans mail letters back to grandparents from abroad. Pay in USD; international cards are accepted. The letter is mailed from inside the US through USPS.
How long does it take?
We mail within 24 hours of payment on business days. USPS typically delivers domestic letters in 2-5 business days.
