Are you accidentally spamming your customers? Make sure you understand the difference between Mailchimp Groups and Lists!
Permission-based marketing is the cornerstone of great email campaigns. We all get far too much spam cluttering up our inbox; no one wants more, even from a business or organization they support! It’s possible to inadvertently spam your email subscribers, not just by adding them to a list without their permission, but also by misusing Mailchimp Groups and Lists.
