There is nothing worse for a marketing company than getting blacklisted by email providers. As an email marketing specialist I have learned a lot as to how email is changing and how to navigate through the storm that is the spam folder. It seems as though Email is always changing but technologically behind the forever evolving web user experience. Responsive design is a necessity for web designers as users are estimated 50% of users are accessing the internet with a mobile device. Email just within the last couple years has started to allow responsive design. Most emails will render differently depending on how the user is accessing them depending on the device, email provider and email application they are using. Email was originally designed for text based messages between professionals. Now nearly every company from large corporations to small local companies market with emails. There are many ways to land your IP address in the spam folder permanently and keeping a positive relationship with both the users and the spam filter is the best way to keep users engaged and continuing to have uninterrupted communication with your subscriber list.
