What Is the Gmail Plus Trick?

The Gmail plus trick (also called plus addressing or subaddressing) lets you add a +tag to your Gmail username. Everything after the + is ignored during delivery, so all mail arrives in your main inbox. The technique is defined in RFC 5233.

How to Use It Step by Step

1

Choose a Tag

Pick something memorable: the service name, a date, a category like "shopping" or "news". The tag can contain letters, numbers, and hyphens.

2

Use It When Signing Up

Enter [email protected] in any signup form. Verification emails will arrive instantly in your inbox.

3

Create a Gmail Filter

In Gmail, go to Settings → Filters → Create new filter. Set "To" as your full plus address. Apply a label or skip the inbox automatically.

When Sites Block the Plus Sign

Some websites use email validation that incorrectly rejects the + character, even though it is RFC-compliant. In these cases, use a dot-trick variation instead — it looks like a regular email and works on all sites.

Not Anonymous
Your base username is visible before the + sign. Anyone who receives your plus address can see your real Gmail username. Use the dot trick if you want to obscure the connection.
