Best Email Marketing Blogs Resource Center 

Mark's blog is an excellent combination of his own tips and advice and abstracts of worthwhile articles he picks up from other online sources. He has plenty of street cred as a best-practices email guy and he has a good eye for articles that both advance the practice for more experienced users and answer basic newbie questions. You'll find references to blogs, newsletters and forum posts that otherwise slip off the radar.

If you're involved in any aspect of e-commerce with an active email channel, this blog is required reading. If it's happening in retail email, Chad White will report it here, including hits and misses in copy and promotions. Especially useful is the Subject Line Index, which you can use to see what your competition is up to and which subject lines are currently most popular. Just be sure you don't end up in Chad's Hall of Shame!

This blog (published by Infacta, an email software and service provider) is well regarded by its competitors. It looks at all aspects of email marketing, sometimes commenting on issues raised by bloggers and sometimes stirring the pot as well with its own perspectives. It deals more with tips, advice and best practices for newsletter publishers than with technically detailed discussions. So, if you need a blog that looks at the issues you as a marketer have to contend with daily, this is an excellent blog to watch.

Laura Atkins maintains a relatively low profile in the noisy world of email and marketing blogs, but she always manages to be at the front of the line with original reporting and commentary on email issues, especially for commercial senders coping with unsolicited email filters, deliverability and ISP issues. She's a consultant who works directly with large senders, so she knows what you're contending with and what you have to correct in both content and technology to send more email. She keeps a close eye on what the big ISPs are up to and often has the first word on changes or decisions that can hurt your deliverability.
