I recently had my MailChimp account suspended. One of my sites is in the ‘make money online’ space. It’s a completely legitimate website, but apparently if your emails contain keywords they don’t like, they will suspend you. I would not recommend using them. Contacting support I just get form responses that are completely unhelpful. There’s no phone support- just account termination. Really bad experience. Luckily, this is a very new site- but imagine if you have thousands of emails and they just shut you down without ANY recourse.
In addition to satisfying legal requirements, email service providers (ESPs) began to help customers establish and manage their own email marketing campaigns. The service providers supply email templates and general best practices, as well as methods for handling subscriptions and cancellations automatically. Some ESPs will provide insight and assistance with deliverability issues for major email providers. They also provide statistics pertaining to the number of messages received and opened, and whether the recipients clicked on any links within the messages.
