Our website sells products in a niche market, and the product lifetime is about 10 years, so we don't get very many repeat customers.
Our company is now branching into another niche market, this time with consumables, as it would be nice to get repeat business.
We have about 14 years worth of emails, but I assume that we should only go back a few years, to cross sell the new company product.
I'm a little concern with spam. These were past customers, and we stated that we would not sell the companies email list.
Since the emails are owned by our holding company, we are just cross selling within our group of companies under the same management.
Going forward, we can cross sell in the "we see your order was delivered, any problems?, buy the way try out our new line of products", type followup message.
I'm a little concerned about customers in the past. Maybe I'm paranoid and just over thinking this.
On one hand it could be misconstrued as spam, on the other it is easier to sell to previous customers than new ones, as a trust relationship has been established.
I figure I start out with small e-mailings for the past customers, to see if there is any kind of back lash.
