The Certified Senders Alliance has been operating in a not for profit capacity for over a decade in a bid to fight spam and improve the delivery of legitimate, permission based email marketing messages. They provide this through advocacy, education, training and a email sender certification service or all-list type technology. The objective of the CSA is to improve the quality of the email channel. The CSA has taken on the task of setting technical & legal quality standards and developing these standards into a certification. The certification has been shown to improve your chances of inboxing at a wide number of mailbox providers.
