Yahoo7, the Yahoo/ Seven Network joint venture in Australia is using full inboxes in its latest campaign.

The spots, which according to Mumbrella were shown briefly last year, involves a love lost because of a full inbox. The pitch is simple: with Yahoo Mail you get unlimited hosting, and the ad ends with a Yahoo yodel that can only be described as Yahoooo-oooo.

The part lost of me though is the problem: are masses of people really suffering from full inboxes? I look at my Gmail account, which I’ve used exclusively from October 2004, and I see 52% full with 142,952 messages archived. Until late last year I used my Gmail account as a backup, downloading all email to a desktop client and leaving everything else as a permanent archive of my correspondence online. Someone using Gmail directly will be deleting emails, where until recently I wasn’t.

Here’s the Yahoo7 email ad. Note that the woman in the ad would appear to be from New Zealand.
