Just to give some details. This is a bought email list in a specific niche. What is the best way to contact this list? I am thinking of emailing about a discount or special offer but that can often look scammy to people and the people will not take the email seriously. How to build trust and make that they have some relation to my company? What software should I use for emailing? I see some people here are selling servers for this. Is that the best option?
