Write to your future self before you know how it turned out

Choose a lock

Timelock. The saved letter cannot be edited. Timelock protects access through the link and removes the sender’s delete option. Copies or keys you retained remain usable.

Timelock costs $3 USD per Postdate. This covers opening dates within one year and 100 MB including encryption and file packaging. Opening depends on drand and Postdate being available, and on the encryption remaining secure. Senders can keep original copies. Postdates can still expire or be removed for abuse. You see the price before you create the link. Read about Timelock.

Send it before it opens

After a decision, you may remember being more or less certain than you were. Write your reasons before you know the outcome. Later, you can compare your original thinking with what happened.

Set the note to open when you expect to know the outcome. You can then read what you thought at the time.

What people see

Before opening

They see a countdown. Any public teaser you wrote also appears.

After opening

They can read the text and download attached files until the link expires. Files supported by the browser can also be previewed.

Before opening, you see a countdown. You can add a calendar event and copy the link. Any public teaser you wrote also appears. The letter stays encrypted until opening. File names and sizes stay hidden too. On the chosen day, the letter opens in your browser. The link expires after the availability period you chose, measured from the scheduled opening time.

Adding a calendar event downloads a file to import into your calendar. Set any reminder there. Postdate does not send opening notifications.

Limits

Standard is free for letters that open within 7 days and are 1 MB or less. Timelock, later dates, or more than 1 MB cost $3 once. You can choose a date up to a year away. Your text and up to 10 files must fit within 100 MB after encryption and packaging. Your Timelock letter stays unchanged. You cannot delete it.

Compare Postdate with scheduled email

A scheduled email is sent later. A Postdate link can be shared now, with the same opening time for every reader. Postdate does not send the link or an opening notification for you. It shows when the Postdate was created.

Common questions

What if I want to add to it later?

Create a second message. The first stays unchanged, so you can compare what you wrote.

Where should I keep the link?

Save it somewhere you check, such as a notes app or an email to yourself. You can also add it to a calendar entry on the opening date.

Can I read it early if something changes?

Neither lock lets you open a message early. The private delete link removes a Standard message and its key. It does not open the message. Keep your own copy if you may need the text sooner.
