How heavy emails are
An email's size hints at its content, from a short confirmation to a message full of images. Since launch.
What the numbers reveal
Our reading of the trends. The figures are raw, but they show how disposable email is really used.
A clear peak hour
More emails arrive around 22:00 UTC than at any other hour. Automated sends probably contribute, but our data can't confirm it.
Sender concentration
The top 10 sender domains account for 59.4% of the emails received since launch.
The service keeps its promise: everything vanishes
Emails older than 7 days are deleted automatically. Only the aggregate counters shown on this page remain. That's deliberate: less stored data, less risk.
Methodology
How we count. How we don't identify. So you can judge the value of this data.
Two ways of counting
The “since launch” figures count every email received and never go down. The “right now” figures show what is actually stored: emails less than 7 days old. They go down as soon as an email is deleted, by its recipient or automatically.
Immediate aggregation, no personal data
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 don't measure
User IP, geolocation, browser fingerprint, email content, keywords, reading behavior, open rates. No profiling metrics.
