How to Use Plus Addressing (+) to Manage Multiple Accounts with One Email

Plus addressing (also called subaddressing) is a feature that lets you add a “+tag” to your email address before the @ symbol.

Example:
If your email is jane.doe@example.com, you can also use:

All messages still arrive in your regular inbox (jane.doe@example.com), but each alias is treated as a unique address.

This is helpful if you:

Scenario	Alias Example
Two businesses	`alex+cleaningbiz@example.com` `alex+bookkeeping@example.com`
Role-based inboxes	`info+billing@example.com` `info+support@example.com`

This isn’t a Pinch feature — it’s supported by many email providers (e.g. Gmail, Fastmail, Outlook).
Some websites don’t accept + in email addresses (due to strict validation).
You can create filters in your email inbox based on the alias (e.g. “move +test emails to a folder”).
