For iPhone · Gmail, Outlook, iCloud Mail and Yahoo Mail · In private testing

The Old and unread tool: 1,949 messages two to five years old, never opened, ready to archive.
The Cleanup screen: 3.7 GB you could clear, with tools for Subscriptions, Old and unread, Duplicates and Large files.
The Large files tool: the biggest attachments in the mailbox, none ticked until you choose.

Screens show Pillarbox's built-in demo mailbox. None of it is anyone's real mail.

Find what your mailbox is actually full of.

Pillarbox reads through your whole mailbox, then sorts the clutter into four piles, each showing why it's there.

  • Subscriptions

    Mailing lists ranked by how much they send against how little you open. Unsubscribe in one tap where the sender supports it.

  • Old and unread

    Years of mail you never opened, grouped by age, oldest first.

  • Duplicates

    The same email delivered twice: same sender, same subject, same size, within hours of each other.

  • Large files

    The attachments taking up the most room. Never ticked for you, because the biggest files are often the ones worth keeping.

The Subscriptions tool, with mailing lists ranked and ticked for unsubscribing.
RetailCo Offers: Unsubscribe. 22 a month, and you have opened 7 of 1064.
Every suggestion shows its reason.

Then it reads like Messages.

Everything you keep becomes a chat. One per person, one per company, newest at the bottom.

  • One chat per person or company. Mum gets a chat, your bank gets a chat, however many addresses they send from.
  • Reply, forward, attach. Write new emails and replies with files, and get ten seconds to undo a send.
  • The filters you'd want. People, Unread, Flagged and Sent, one tap away.
The Chats list in the demo mailbox.
A conversation with Mum shown as chat bubbles, including Sunday lunch? and an attached holiday-photos.zip.

Nothing's gone until you say so.

Undo it

Archiving, binning and marking as read can all be undone from the app.

30 days in the Bin

Binned mail goes to your provider's Bin, where it's kept for about 30 days.

Your call

Mail is only deleted for good when you choose Delete forever in the Bin yourself.

Your mail stays yours.

Pillarbox needs access to your mailbox to tidy it. Here's exactly what that means.

  • No message text on our servers

    Our server keeps what it needs to sort your mail: sender, subject, date and size. Never the text of your messages.

  • Recent mail stays on your iPhone

    Message text is kept in the app's private storage so it opens instantly, and deleted when you sign out.

  • No ads, no tracking, nothing sold

    Your mail runs the features you see and nothing else. It's never sold, never shown to advertisers and never used to train AI.

  • Take it with you, or delete it

    Download everything we hold about you, or disconnect a mailbox and delete its data, from inside the app.
Read the privacy policy
