Ask HN: Would you exchange space in your email newsletter to get exposure?

Every business is looking for ways to achieve new users/customers. Making inroads using traditional/online advertising techniques can be pretty expensive, so what if you found another business willing to exchange space in their email newsletter for space in yours?

Of course, you probably wouldn't want them to be a competitor - that's fairly obvious. Taking the example of a classy restaurant, they might exchange newsletter space with a high end men's clothing store. They might even consider another restaurant with a different dining experience and/or in a nearby town, because as a restauranteur you know that people move between restaurants anyhow, so play that knowledge as an advantage.

You both gain exposure to a new audience and maybe website visits that you could convert into customers.

Would you do it? Why or why not?
