Plus addressing vs separate Zanon identities

Plus addressing is already enabled on zanonmail.com. Mail to user+anything@zanonmail.com lands in the same mailbox as user@zanonmail.com. It is useful for labelling a signup. It is a poor firewall: many sites strip the tag, and the local part before the plus is still visible.

Use a real address when

You want to send from a different From line, cut the address off without touching the others, or keep a bank from seeing the same local part as a shop. That consumes quota. Plus tags do not.

Finding the tag later

Search plus:netflix or to:user+netflix@zanonmail.com. Filters can also match the To field and file those messages into a folder.
