Gmail Aliases
Gmail alias generator: every version of your address that lands in the same inbox. And how to read one backwards.
Gmail ignores dots in the part before the @, and treats anything after a + as a label. So one account has thousands of working addresses. Generate them, or paste an alias to find out whose inbox it really reaches.
Why this works
Gmail ignores full stops in the local part — the bit before the @. [email protected], [email protected] and [email protected] are all the same mailbox. It also treats everything after a + as a label that it strips before delivery, so [email protected] arrives in the same place. And googlemail.com is an alias of gmail.com.
None of this applies to other providers. Outlook, Yahoo and most business domains treat dots as significant, so the same trick will bounce.
What it's genuinely useful for
Tracking who sold your address. Sign up with [email protected] and if spam later arrives at that exact label, you know precisely who leaked it.
Filtering. Gmail can file mail by the label it arrived at, so +receipts can skip the inbox entirely.
Finding hidden duplicates in a list. This is what the second tab is for. Fifty rows that look like different people can be one person, and if you're paying per address to verify a list, or sending to it, that matters.
What it is not good for
It won't get you multiple free trials — services that care have detected this for years, and stripping the dots is the first thing their signup checks. Some sites also reject the + character outright, which is their bug, not yours.
And it doesn't hide anything. Anyone who knows the rule can read your real address straight off the alias, which is exactly what the second tab does.
What the Gmail alias generator does
Gmail ignores dots before the @ and anything after a plus sign, so one Gmail account can receive mail at many different-looking addresses. This tool works both ways: it lists the alias versions of your own Gmail address, and it takes a pasted list of addresses and shows which ones really go to the same inbox. That makes it handy for sign-up tracking and for finding hidden duplicates in a list.
Benefits
- Two tools in oneUse the Generate aliases tab to create versions of your address, or the Find the real address tab to work backwards from aliases.
- Plus labels for trackingTurn your own labels, like shopping or receipts, into plus addresses so you can see who shares or leaks your email.

- googlemail.com optionInclude googlemail.com versions, which reach the same Gmail inbox.
- Finds hidden duplicatesPaste a list, even messy text, and see how many pasted addresses collapse into each real inbox.
- Clear countsSee totals for addresses, dot variations and plus labels, or for pasted addresses, real inboxes and hidden duplicates.
- Easy to exportCopy the results, or download aliases as TXT or CSV and real addresses as a CSV that pairs each real inbox with how it was written.
- Honest about limitsIf you enter a non-Gmail address it explains that the dot trick won't work there instead of producing addresses that bounce.

Common questions
Does Gmail really ignore dots in addresses?
Yes. [email protected], [email protected] and [email protected] are all the same mailbox. googlemail.com is also an alias of gmail.com.
What is plus addressing?
Anything after a + in a Gmail address is treated as a label and stripped before delivery, so [email protected] arrives in the same inbox. It's useful for filtering, and for finding out who leaked your address when spam later arrives at that exact label.
Does this work with other email providers?
The dot trick is Gmail-specific — Outlook, Yahoo and most business domains treat dots as significant, so the same address would bounce. Plus addressing is more widely supported, but not universally.
Can I use this to get multiple free trials?
No. Services that care have detected this for years, and stripping dots is the first thing their signup checks. It also hides nothing: anyone who knows the rule can read your real address straight off the alias.
How do I find hidden duplicates in a list?
Use the second tab. Paste your addresses and they're collapsed to real inboxes, showing how many variations point at the same person. That matters if you're paying per address to verify a list.
