Manage your email marketing with a service like MailChimp. A free account allows you to manage your email lists with up to 2,000 subscribers, build newsletters either from scratch or by selecting from hundreds of pre-designed templates, send up to 12,000 emails per month, and most importantly track all of your results. Additional features such as high volume sending, auto responders and transactional emails can be added for a nominal monthly fee.
Why is it so important to have a quantifiable, reliable email provider? Because your email list is one the most important assets you have for connecting with customers directly.
