How it works

Write it today. We'll deliver it when it matters.

Write a letter to someone you love, or to your future self. Choose the moment it should arrive. We keep it private and safe until then.

An illustrated road through life: first steps, turning 18, a wedding day, becoming a parent, a big day, and remembered always

Writing a letter

Four simple steps

We guide you one step at a time, with big buttons and plain words. Everything is saved as you go, so you can stop and come back whenever you like.

  1. Who it's for

    Their name and email address. You can choose to let them know now that a letter is waiting for them; we never show what it says. (Letters to yourself skip this step.)

  2. When it arrives

    On a date, such as a birthday or anniversary; when something happens, such as their wedding; or after you're gone. For birthdays, we work out the date for you from their date of birth.

  3. Write it

    Give it a title, write your letter, and add up to 5 photos if you like. Photos straight from your phone are fine; we resize them for you.

  4. Check and save

    Read it through, change anything you need, then press save. You can still change your letter later, right up until it's delivered.

When it arrives

Three ways your letter can arrive

You choose one when you write the letter, and you can change it later.

A pocket watch

On a date

For the days you know are coming

Your letter is released on the day you choose.

  • Any date, up to 80 years ahead
  • An 18th, 21st, 30th, 40th or 50th birthday, or any other age
  • A wedding anniversary

For example: a letter to your newborn grandchild, to open on their 18th birthday.

When something happens

For moments without a date

We let them know a letter is waiting, without saying what it says. When the moment comes, they sign in, tell us it has happened, and open it.

  • The morning of their wedding
  • The birth of a first child or grandchild
  • Retirement, or any moment you describe

For example: a letter for your daughter to read on the morning of her wedding.

After I'm gone

A letter to leave behind

If you haven't signed in for six months, we email you to check in. Only if several check-ins over the following weeks all go unanswered is your letter released.

  • Several reminders, weeks apart
  • One click, or signing in, keeps it waiting
  • We email them when it's ready to read

For example: a letter to each of your children, sharing your love and pride one last time.

Receiving a letter

What your loved one sees

Letters are never sent by email. Your loved one reads theirs in their own private Letterbox.

  1. An email to say a letter is waiting

    If you chose to let them know, or for a "when something happens" letter, they get a short email straight away. Every letter also sends an email on the day it's ready to read.

  2. They create a free account

    Using the same email address the letter was sent to, so only they can open it.

  3. They confirm the moment, if needed

    For "when something happens" letters, they tick a box to confirm the moment has arrived.

  4. They open your letter

    Your words and photos appear in their Letterbox. They can read them again whenever they like, print them, or download a copy to keep.

Keeping it safe

Your words, kept private and safe

Encrypted when stored

Every letter and photo is encrypted before it's saved. We never read, sell or advertise with your letters.

Never sent by email

Emails only ever say a letter is waiting. The letter itself is only shown to the person it's for, once they've signed in.

Saved as you write

Your letter saves itself as you go. Close the page, come back next week, and carry on where you left off.

Backed up, and a promise

Letters are backed up in more than one place. If we ever had to close, you'd get advance notice and your letters back. Our Vault Promise

Change it any time

Edit your letter as often as you like until it's delivered. Letters to yourself can be sealed when you're finished.

Made for everyone

Large, clear buttons and plain words. Use the three A's at the top of any page to make the text bigger.

Letters to yourself

Write to the person you'll become

Letters to your future self are free: up to 10 of them, on any date up to 50 years ahead. They're a lovely way to mark a year, remember a dream, or send yourself encouragement.

To write to the people you love, choose the Three-Chapter or Legacy Vault, each paid once. See the plans

A few honest details

Use an email address they'll keep
Letters reach people by their email address, so please choose one they're likely to keep for many years, and check it carefully.
Photos
Up to 5 photos per letter, as JPG or PNG. Big photos are resized automatically.
Not a legal service
Milestone Vault delivers letters. It isn't a will or a legal service, and it doesn't verify deaths or events; the people involved confirm them.
Our best effort, honestly
We work hard to deliver every letter at the right moment, and keep trying if something goes wrong. Read more in our Terms and Privacy Policy.
