I have been in and out of this business for many years, but mostly out of it for past 5 years or so. I recently came across a technique to almost guarantee any mail that inboxed would be opened. I don't know what current rates are, but it used to be only 2/3% of inboxed mail was ever opened, so to get 95% opened is a major gamechanger. The question I have is how to use the knowledge. I don't really want to go back to bulletproof sites and unless things have changed I can't imagine CPA accounts would last very long. Any suggestions ?
