One Gmail. Infinite Unique Variations.

Frequently Asked Questions & Technical Specifications
Understanding Gmail's RFC 5233 subaddressing & dot-insensitivity rules
Why does Google ignore dots in email addresses?
According to official Google Mail documentation, Gmail usernames are dot-insensitive. Google does not recognize periods as characters in usernames to prevent impersonation and typos. john.smith@gmail.com and johnsmith@gmail.com are mathematically identical in Google's mail server.
Why do external websites see them as different accounts?
Most websites and registration systems follow standard string-matching databases without Gmail-specific sanitizers. To their database, j.ohn@gmail.com and jo.hn@gmail.com are completely distinct strings, allowing multiple registrations with the exact same mailbox.
How does the mathematical $2^{N-1}$ formula work?
For a username of length $N$, there are $N-1$ intermediate spaces between letters where a dot can either exist ($1$) or not exist ($0$). This creates a binary sequence of $2^{N-1}$ unique permutations. An 8-letter username yields $2^7 = 128$ pure dot combinations!
What is the difference between @gmail.com and @googlemail.com?
In the United Kingdom and Germany, Gmail originally operated under @googlemail.com due to trademark disputes. Google maintains global MX alias routing for all accounts, so any email sent to @googlemail.com automatically lands in your inbox.
