Use email marketing to promote your business.
MailChimp and Constant Contact are 3rd party programs designed specifically for sending email.
Can't I just send bulk email from my regular email?
No. Due to the CAN-SPAM Act, you must comply with all of the rules and regulations for proper email marketing, such as giving people the option to "opt-out" of your emails, and many other rules.
MailChimp and Constant Contact
MailChimp and Constant Contact are the two 3rd party programs we suggest, however we may be able to assist you if you already have one set up with a different program. We find that the user interface of MailChimp is the easiest to use, plus they do a lot of cool techy stuff that makes things useful on our end. We also really like the monkey.
