A recent study by e-mail service provider Mailchimp indicates that purchased, rented or scraped e-mail lists offer no return on investment for marketers.

Most of the popular e-mail service providers maintain strict policies against sending e-mails to users that have not opted in to receive messaging. Beyond the obvious legal reasons to avoid this practice, e-mails sent to purchased lists have miniscule open rates and sky-high unsubscribe rates.
In short, spam does nothing to help your business (and has many negative ramifications). Just don’t do it.
