Hi Pete, thanks for your comment.
About the link, I think you are regarding to my earlier article called: How Email Marketing Automation can save you time: it’s in the Data. It does mention costs / money. Even more because time = money 🙂
To quote: “Efficient use of email marketing can be a real cost and time cutter. Solid e-mail marketing system can create the same quality of e-mail campaigns while increasing productivity.
Because preparing and sending email newsletters are steps within each and every campaign, those tasks can add up to a lot of hours. Yet, this time investment is often overlooked when calculating the the true costs of an email marketing system.”
