Seems a 4x6" postcard on its own could have three 4x2" ads on the back, and one 4x3" ad on the front (other half has the delivery address)
That's only 3 sales to cover the EDDM fee and hard postcard costs. A lot more bearable than having to maintain 8-9 sales IMO.
Anyone else do this? Or does the strength of the mailer fall a lot when it gets smaller and has less advertisers?
If I did this I think it'd be 3 food places with discounts, and my We Buy Houses ad.
