So, i know the basics of email marketing. Find a niche, get organic opt ins, create a converting campaign etc. But im wondering, lets say i have over 250k emails, is there any way to profit off of said emails? Because they arent targeted, they didnt sign up for anything, i just have them. Should i sell them, email them, or what are your guys opinions? I can grow said list to over 5million within 30 days if i find a way to actually profit off of them. Just figured you guys would know best.
