The problem is that your list is so big (both long and we were working with a lot of columns and a few equations) that Excel on my computer couldn’t handle it.

Use personalization. Personalizing the content of your emails (depending on your segment from Chapter 3) will make it so much more relevant and valuable to them. Personalization goes beyond sticking your subscriber’s first name into the email. You need to tailor the actual content of the email to address their needs.

Very interesting indeed. I am currently using MailChimp and reading through this article, I am wondering when it was written as features have changed in MC, the tracking has more than is mentioned here, there is now a visual drag and drop editor to create custom campaigns, etc. I am not familiar with aweber but maybe some things have also changed on their side.

After you have entered your "List Name" you will need to enter a "List Description." Here is where you will describe the kind of information you'll be sending from this list. There is a 400 character limit for the "List Description." Subscribers will see your "List Description" on the unsubscribe page if they ever go to unsubscribe from your list. Once you are done entering your "List Description" click the "Next Step" button.
