Inbox
Email

Every mailbox you own or share, in one inbox.

Inbox puts your own mailboxes and the ones colleagues have shared with you into one colour-coded list. It reads mail live over IMAP, so nothing has to sync first, and adds snooze, reminders, team comments and send-later on top.

What Inbox does

For people and small teams who handle several addresses, such as a shared support or sales mailbox, or a manager and an assistant.

One inbox

  • All mailboxes together

    Every mailbox you can reach in one list. A mailbox that can't be reached is named, not silently left out.

  • Share a mailbox

    Give a person or group read-only or read-and-send access, with an optional end date.

  • New mail as it arrives

    Messages appear the moment they land, with browser notifications you control.

  • A colour per mailbox

    See at a glance which address a message was sent to.

Get through the day

  • Snooze and reminders

    Bring a message back later, or flag it as to-do, waiting or reference.

  • Team comments

    Leave notes and @mentions on a message. They are never sent to the customer.

  • Send later and templates

    Schedule a send and reuse replies, ranked by how often you use them.

  • Filters and search

    Write your own filters, search live over IMAP and act on many messages at once.

Safe by default

  • Scripts never run

    Mail is cleaned, sandboxed and blocked from running scripts, in three separate layers.

  • Remote content blocked

    Images and trackers load only when you allow them, per mailbox or sender.

  • Sender check

    A badge shows which domain actually authenticated the sender.

  • A spam filter that explains itself

    It learns from your choices, runs in your browser and shows why it scored a message.

Connected to your business

  • Knows your customers

    With Overwatch, Inbox recognises customers and links to their record.

  • Thread summaries

    Summarise a long thread with AI. The button tells you the text goes to a US AI provider.
