How single email ID is biased as multiple email IDs?

1
Using a dot or period (.)
Gmail addresses have "dot blindness" means dot/dots are not recognized by Gmail.

Gmail addresses have "dot blindness" means dot/dots are not recognized by Gmail. This means if there are dots in any gmail address, Gmail will simply discard all those dots and consider the left part to be an email address. Let's have a look on some examples:

[email protected](original email id)

[email protected](newer email id)

[email protected](newer email id)

[email protected](newer email id)

and so on, we can generate multiple email addresses by just placing "." here and there in already existing address. Mail sent to any of the above email address would be directly placed in the inbox of original id i.e [email protected]

2
Using plus ( "+" ) proceeded by any number of characters

Next way to generate a newer email address is to add "+" and then any number of characters. Once again, Gmail will discard the "+" sign and all the characters placed to the next of "+" sign . Let's have a look on some of the examples:

[email protected](original email id)

[email protected](newer email id)

example+1gmail.com (newer email id)

[email protected](newer email id)

and so on. Again, mail sent to any of above address will be delivered to the inbox of " [email protected]".

3
Using domain name "@googlemail.com"

The last way is to use domain "@googlemail.com" instead of "@gmail.com". Let's have a look on examples:

" [email protected]" and

both are treated as same.You can use combination of these methods too as :

[email protected], and so on...

So now you are able to generate any number of email addresses by using only single email address, instead of going for cumbersome task of signing up for 1000's of times on different sites to create multiple accounts.
