Subaddressing
Subaddressing (also called plus addressing or tagged addressing) lets you create unlimited variations of your email address without creating new mailboxes. Append +tag to the local part of any address.
How it works
Email sent to you+anything@yourdomain.com is delivered to you@yourdomain.com. The +anything part is called the tag. You can use any tag you want.
Examples
| Address | Delivered to | Use case |
|---|---|---|
| you+github@example.com | you@example.com | Track GitHub signups |
| you+newsletters@example.com | you@example.com | Filter newsletters |
| you+shopping@example.com | you@example.com | Online purchases |
Filtering by tag
The tag is preserved in the delivered email headers. You can create filters in your email client or with Sieve rules to sort email by tag into folders automatically.
Notes
- Subaddressing is enabled by default on all mailboxes. There is nothing to configure.
- Some websites reject email addresses containing a
+character. In those cases, use a catch-all address instead. - You can reply from a subaddressed address. The tag will appear in the From header.
