How Mailbox analyzer works

This tool takes stock of your mailbox: how many messages, what size, which folders take up the most space, who writes to you most, and how it all spreads over time. It changes nothing — it's a survey, useful before tidying up or switching provider.

Step by step

  1. 1 You enter the credentials for the mailbox to analyse.
  2. 2 We open your mailbox read-only and go through the message headers — not their contents.
  3. 3 The report appears: size per folder, top senders, breakdown by year.

What to put in each field

  • Email address *
  • Password **
  • Incoming server (IMAP) ***

* The address of the mailbox you want an inventory of.

** The password for that mailbox, or its app password.

*** Filled in for you when the provider is recognised.

Good to know

  • The contents of your messages are never read: only their size, date and sender are examined.
