Hiya, I've been approached by a company looking to market my forum niche related products via email to my members. I've 3 motorcycle forums, the largest with around 7000 members, and in total over 10,000 members. I can design and send it to my 10,000 members (using Sendy via Amazon SES to send bulk mail). Has anyone and idea of how much I should charge for this? Cheers, Rob.
