Gmail Washer
Gmail treats four things as meaning nothing at all: dots in the name, anything after a +, upper- and lower-case letters, and the difference between gmail.com and googlemail.com. So all four of these are one mailbox, and mail to any of them lands in the same place:
| Written as | Delivered to |
|---|---|
| j.o.h.n.smith@gmail.com | johnsmith@gmail.com |
| johnsmith+netflix@gmail.com | |
| john.smith+shop@googlemail.com | |
| JohnSmith@gmail.com |
Paste one address or a whole list below, and this reduces every variant to the single address behind it. Useful in both directions: to clean duplicates out of a list, and to find out whether two addresses that look different are in fact the same person.
Two things worth knowing before you rely on the result
j.smith@ and jsmith@ are two different mailboxes belonging to two different people. This tool strips dots from every address you give it, not only Gmail ones — that is how the page has always behaved, and changing it quietly would break lists people have been processing here for years. Feed it non-Gmail addresses only if you know that is what you want.The + tag is more widely supported: many providers honour it, and some do not. Where it is not supported, the address with the tag simply does not exist — which is its own kind of useful thing to discover.
The opposite direction
This page collapses variants into one address. If you want to go the other way — produce variants of an address you own, so each service gets a different one — that is Fake Gmail Generator.
