How to Use Duplicate Email Addresses

Using Email Aliases with the Plus Sign

Many email services let you create easy-to-manage aliases by adding a plus sign (+) and extra text after your username. These aliases can help organize emails, track signups, or filter messages — all while sending mail to your main inbox.

✉️ How it works

If your email is family@gmail.com, you could use:

• Family+wife@gmail.com
• Family+husband@gmail.com
• Family+kid@gmail.com

All emails will still arrive at family@gmail.com 

✅ Providers that support this

• Gmail
• Outlook / Hotmail
• iCloud
• Some other modern email providers (check your provider’s help center)

⚠️ Providers that don’t support this

• Yahoo Mail (does not support plus sign aliases)
• Some older or smaller providers

? Why use email aliases?

• Organize your inbox: Set up filters or labels automatically.
• Track signups: Know who shared your address.
• Block spam: If an alias starts getting spam, filter it out.
