I am just wondering if this will work at all, but for my business I run 4 stores in the south of the UK & these stores are e-cig stores, we do well but I just clicked that our online website does have an opt-in newsletter list that we have actually never used! To be honest I completely forgot it was there, but I went and looked and we have over 700+ emails, names, phone numbers.
Is there anything I could do with this list outside of my business to be able to make some money? Like sell ads to this email list etc? I just have no idea how to go about it?
These are obviously interested customers in the stop smoking niche so there must be something we could do?
