A web-based interface is often available to allow people to subscribe, unsubscribe, and change their preferences. However, mailing list servers existed long before the World Wide Web,[1] so most also accept commands over email to a special email address. This allows subscribers (or those who want to be subscribers) to perform such tasks as subscribing and unsubscribing, temporarily halting the sending of messages to them, or changing available preferences - all via email. The common format for sending these commands is to send an email that contains simply the command followed by the name of the electronic mailing list the command pertains to. Examples: subscribe anylist or subscribe anylist John Doe.
AI should be seen as the solution to a large number of your processes, rather than another terrifying technological advance to get your head around! It strives not only to replace the traditional (and somewhat arduous) segmentation processes currently in action but to completely transform the levels of relevancy that we, as marketers, are capable of providing to consumers.

Media is being consumed in ways that we could never have envisaged back at the inception of email. It's our job as email marketers to evolve with these changes by providing content that fits seamlessly into increasingly busy schedules and onto an increasingly varied number of devices. In turn, we can reap the rewards by successfully encouraging higher levels of engagement with the emails we're sending.

Keep the subject line and pre-header short: The subject line is crucial. Keep it short so the reader knows exactly what the email topic is about. And the pre-header text (also known as snippet text), don’t let it go to waste by using “To view this email in your browser…”. Instead, summarize the email or include a call to action (i.e., Use “FREESHIP” to get free shipping).
