Many email providers, including Gmail and Microsoft 365 (depending on configuration), support a feature called email aliasing or plus addressing. This technique allows you to add a plus sign (+) followed by any text to your email address without creating a new mailbox.
Important Considerations
-
Not all email providers support plus (+) addressing.
-
Some websites may reject email addresses containing a plus sign.
-
Plus (+) addressing does not create a separate mailbox; all messages arrive in the same inbox.
-
Replies sent from your mailbox typically appear to come from your primary email address unless additional aliases are configured.
Best Practices
✓ Use meaningful labels after the plus sign.
✓ Standardise naming conventions:
+salesforce
+donation
+events
+training
+testing
✓ Create inbox rules to automatically sort incoming messages.
✓ Use unique aliases when signing up for external services to improve tracking and security.
Summary
Plus (+) addressing is a simple and effective email management technique that allows users to create unlimited email aliases by adding a "+" sign and custom text to their existing email address. It helps organise messages, track email usage, and improve inbox management without requiring additional mailboxes.
