How Email Aliases Work with SaneBox
If you receive email at multiple addresses that all deliver to the same mailbox, SaneBox can recognize those addresses as email aliases.
The Email Aliases settings page lets you tell SaneBox which addresses belong to you and control how messages sent to each address should be filtered.
What Is an Email Alias?
An email alias is an additional email address that delivers messages to your primary email account.
For example, you might have:
- you@company.com
- sales@company.com
- you+shopping@gmail.com
If mail sent to those addresses arrives in the same mailbox, SaneBox can treat them as aliases of your primary address.
Why Did SaneBox Add an Address I Didn’t Add?
- You don’t have to manually add every alias. SaneBox automatically looks for other email addresses that receive mail in your mailbox and may add them to your Email Aliases page.
- This helps SaneBox understand which messages are addressed to you, even when they weren’t sent directly to the primary email address connected to your SaneBox account.
Occasionally, SaneBox may detect an address that doesn’t actually belong to you. This can happen because of the way a message was addressed or delivered.
If you see an unfamiliar address, don’t worry. You can tell SaneBox that the address isn’t yours using the Is this you? setting.
Find Your Email Alias Settings
- Go to your SaneBox Settings and select Email Aliases.
- At the top of the page, you’ll see your Primary Address. Below it, you’ll find any aliases SaneBox has detected or that you’ve added yourself.
- You can also enter another address in the Add field if you receive mail at an alias that isn’t already listed.
Understanding Your Alias Settings
Each alias has three settings that control how SaneBox handles it:
-
Move to
Move to controls where messages sent to that alias should go. The default setting is: Let SaneBox Decide With this selected, SaneBox filters messages sent to the alias normally, using your existing SaneBox filtering and training. - You can also select a specific available folder if you want messages sent to that alias routed there instead.
- For example, if you have an email address used primarily for newsletters, you could choose @SaneNews as its destination.
If you don’t see the folder you want in the menu, make sure that feature or folder is enabled for your SaneBox account. - Training
The Training setting controls how your existing SaneBox training interacts with the rule you’ve selected under Move to. The default option is Default. This becomes particularly useful when you’ve selected a specific destination under Move to, but also have training associated with individual senders.
For example, suppose you’ve configured:
shopping@example.com → @SaneLater
but you’ve previously trained an important sender to your Inbox.
The Training setting determines how SaneBox handles that conflict between the alias destination and your existing training.
-
Is this you?
Is this you? tells SaneBox whether the alias actually belongs to you. -
Choose:
- Yes if you receive email at this address and it should be treated as one of your addresses.
- No if SaneBox automatically detected the address but it doesn’t actually belong to you.
This is especially useful if you discover an unfamiliar address that SaneBox automatically added to your aliases.
Using Aliases to Automatically Organize Email
You can use Move to to organize messages based on the address that received them.

If you don’t need special handling for an alias, simply leave Move to set to Let SaneBox Decide. SaneBox will continue filtering those messages normally.
Adding an Alias Manually
If SaneBox hasn’t automatically detected one of your aliases:
Go to Settings → Email Aliases.
Begin typing the email address in the field above your alias list.
Select or enter the address.
Click Add.
Review its Move to, Training, and Is this you? settings.
What If an Address Isn’t Mine?
If SaneBox automatically detected an address that doesn’t belong to you, set Is this you? to No.
You don’t need to worry simply because an unfamiliar address appears on this page. Automatically detected addresses are listed so you can confirm whether or not they actually belong to you.
Need Help?
If SaneBox is filtering messages sent to an alias differently than you expect, contact SaneBox Support. Let us know the alias, where the message was delivered, and where you expected it to go.
