Gmail alias generator: dot and plus variants of one Gmail address
In short: Type a Gmail address and get its dot variants and +tag variants, all reaching the same inbox, with the true count of variants. Limit: Works for gmail.com and googlemail.com only; other providers treat dots and plus signs differently.
A Gmail alias generator lists the other spellings of one Gmail address that reach the same inbox. Gmail ignores periods in the username and delivers name+tag@gmail.com to name@gmail.com, so jane.doe, j.anedoe and janedoe+news are all one mailbox. Type the address and get the dot variants, the +tag variants for tags you choose, and a CSV.
Check that the address behind your aliases exists.

How do I make Gmail aliases from one address?
- Type your Gmail address, or just the name before the @.
- For +tag variants, add the tags you want, such as news, shop, receipts, separated by commas.
- Press List the variants. The dot variants are shown with their true total, and each +tag address is listed.
- Copy them or download the CSV, then use them for filters and test sign-ups on your own address.
Example
- You enter
- The address
janedoe@gmail.comwith the tagsnews, shop. - You get
- 64 dot variants (janedoe, j.anedoe, ja.nedoe and so on, all 64 listed) and 2 tag variants, janedoe+news@gmail.com and janedoe+shop@gmail.com, all delivered to one inbox. Download the CSV.
- Limits
- Gmail and googlemail.com only. Up to 200 dot variants are listed and the true total is shown; up to 50 tags. Runs in your browser.
How do Gmail dots and plus tags work?
Gmail ignores periods in the username, so jane.doe@gmail.com and janedoe@gmail.com reach one inbox, as Google's help explains. Gmail also delivers name+anything@gmail.com to name@gmail.com, which lets you tag the address you give a site and filter on the tag.
A name with n letters has 2 to the power n minus 1 dot variants, because a period can go between any two letters or not. A 10-letter name has 512; a 20-letter name has over half a million, so the tool lists the first 200 and reports the true total.
What are aliases good for?
A +tag per site shows who sold or leaked your address and lets you filter mail on the tag. Dot variants are less useful: some sites treat jane.doe and janedoe as two accounts even though Google delivers both to one mailbox.
Use aliases on your own address and within each site's terms. Many sites strip or reject +tags, so test the one you need.
How do you treat aliases in a list?
In a list, every variant of one inbox is the same recipient. The Gmail address normalizer reduces them to one row, and the strip plus tags tool removes the tags. To check the base address exists, verify it.
Who uses this tool, and for what?

What can’t this tool tell you?
- Works for gmail.com and googlemail.com only; other providers treat dots and plus signs differently.
- Every variant reaches the same inbox, so aliases don't create separate mailboxes or accounts.
- Dot variants are capped at the first 200; the total is shown.
Common questions
- Do Gmail dots make a different email address?
- No. Gmail ignores periods in the username, so jane.doe@gmail.com and janedoe@gmail.com are the same inbox.
- How many dot variants does a Gmail address have?
- A name with n letters has 2 to the power n minus 1 variants, counting the plain name. A 10-letter name has 512.
- Does name+tag@gmail.com reach name@gmail.com?
- Yes. Gmail delivers mail for a +tag address to the base inbox, so you can filter on the tag.
- Does this make new Gmail accounts?
- No. It lists spellings of an address that already exists. Every variant reaches the one mailbox.
- Is it free?
- Yes. It runs in your browser with no account, and nothing you type is sent anywhere.
- Do all websites accept plus addresses?
- No. Some sites reject the plus sign or strip the tag, so try the variant on the site before relying on it.

A tidy list can still be full of dead addresses.
Extracting, deduplicating and syntax checks all work on the text of an address. None of them can tell whether the mailbox exists. Only the server that hosts it can answer that, through an SMTP check, and that is what the paid product does.
- Upload the cleaned file as it is: CSVs up to 100,000 rows
- A real SMTP mailbox check on every row, with catch-all detection
