This is a hidden feature in Gmail that you might not be aware of. Signing up for various services using the same email address often lead to a leak and you might end up getting lot of spam emails. This feature in Gmail that you can use to generate unlimited number of aliases for your single email. So how does this work?
As I've shown in the picture above, say your email address is email@example.com if you add a + sign after user and before @ Gmail will ignore those characters and will deliver the email to firstname.lastname@example.org. So, I could register say for Netflix using email@example.com and would still received email in my inbox. Now, I can continue to do this for all services and any websites.
So what is the usefulness of this alias email? You can use this to filter your email. Say if you receive spam from a particular address you know which web-service is selling your information to third party websites. Say I sign up for a newsletter for a random website and the email I use is firstname.lastname@example.org and I started getting useless junk email on that address. Then I could auto delete all email received in that address in Gmail. Here are the steps to create a filter in Gmail.
Step I: On your browser open gmail and in the search bar click the search options:
Step II: In the search options enter the defaulting email address as shown below (email@example.com). Then click create filter
Step III: Now you can select which options you want to do with email received in that address. Like Archive or delete it.
This is a handy option build in Gmail. If you are using workspace for your personal domain on Google Workspace the same alias workaround as shown above is also working.
