Everything we know, in open access
Every figure mail123.fr collects is published here, in real time. No private dashboard, no investor-reserved data. If you write about disposable email, spam or privacy, these numbers are yours.
Overview
Cumulative counters since service launch, never decremented, even when emails are auto-deleted at 7 days. Represent total historical activity.
Top 10 | who sends the most to disposable inboxes
Most frequent sender domains since launch. Historical cumulative counter, a domain remains in this top even if all its mails were auto-deleted.

Hourly activity (UTC)
At what time of day emails arrive, since launch. The cumulative temporal pattern reveals spammers' and automated campaigns' habits.
Weekly activity
Weekday vs weekend pattern since launch. Human sign-ups typically concentrate on weekdays, automated spam is less discriminating.
Size distribution
The average size of an email received on a disposable inbox gives hints about its content: short confirmation, HTML newsletter, or heavy message with images.
Currently online · real disk state
Exact mirror of emails physically present on the server right now. Updated on every arrival and every deletion (manual or auto-cleanup at 7 days). If you're reading this page now, that's what mail123 actually contains.

What the numbers reveal
Editorial reading of patterns. The numbers are raw, but they tell something about how the internet really uses disposable email.
Received mails are overwhelmingly confirmation and activation emails. Small, automated, short. Humans sign up, verify, leave. The service is used for what it is: an anti-spam airlock.
Daily activity peak falls around 22h UTC. No coincidence: that's the typical trigger time for automated email campaigns across Europe and North America.
A handful of domains account for the majority of traffic. Big players (Google, Microsoft, SaaS platforms) dominate the sender list, reflecting their dominant position on online sign-ups.
All emails older than a few days are automatically erased. The counters above represent a rolling window, never a historical cumulative. It's intentional, less stored data = less risk.
Methodology
How we count. How we don't identify. So you can judge the value of this data.
-
2-database architecture: historical vs present
Sections 01-05: historical DB. Incremented on every incoming mail, NEVER decremented. Represents cumulative arrival activity since launch.
Section 06: live DB. Exact mirror of disk state, incremented on arrival, decremented on every deletion (manual, auto-cleanup, admin). Represents real state right now (mails ≤ 7 days old, per our automatic deletion policy). - Immediate aggregation, no PII The sender domain (part after @) is extracted, counted, then the mail itself remains linked only to the temporary inbox. No cross-reference IP ↔ content ↔ recipient is kept.
- Hours in UTC Hourly activity is measured in UTC to stay internationally comparable, and avoid the complexity of timezones and daylight saving time.
- What we do NOT measure User IP, geolocation, browser fingerprint, email content, keywords, reading behavior, open rates. No profiling metrics.
