Using the plus symbol, an infinite number of email addresses may be created.
For example, let's pretend your email is email@example.com. When you include +example before the @ symbol, messages received to firstname.lastname@example.org are delivered straight to your primary inbox.
It converts your email address from one to an infinite number of alternatives.
And why should it be utilized ?
To arrange the email inbox.
Using rules, you may automatically sort your email messages based on the recipient. For example, you may establish JackWilsonemail@example.com for all of your online shopping accounts and utilize it to filter all of your conversation into a certain folder.
In addition, it facilitates future searches when you forget the name of a certain website.
You will not miss important e-mails
You may highlight important emails across all email providers (for example your mother, lawyer etc.). However, this is ineffective unless you know the email address to which they will send the message.
If you share a secret email address (such as JackWilsonfirstname.lastname@example.org) with someone whose messages you don't want to miss, you may use rules to ensure that any messages sent to it from any address will be shown at the top of your mailbox.
You will be aware of who sells your data to marketers.
Suppose you enrolled up for the dating app Tinder using the email address Jackwilson+Tinder@gmail.com. After some time, you get an advertisement email from a random firm, addressed to Jackwilson+Tinder@gmail.com. However, you would not know this if you joined up using your primary email address.
Additionally, you may block any messages sent to Jackwilson+Tinder@gmail.com using inbox rules.
The Gmail technique offers you with all the benefits of having a second, third, fourth, and fifth dedicated email account without the hassle of creating new ones.
