What the numbers reveal

Editorial reading of patterns. The numbers are raw, but they tell something about how the internet really uses disposable email.

Disposable email, main use: verification

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.

Hourly peaks expose the marketers

Daily activity peak falls around 22h UTC. No coincidence: that's the typical trigger time for automated email campaigns across Europe and North America.

Sender concentration

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.

The service keeps its promise: everything vanishes

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.
