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. I have a ton of memory on my computer, but it wasn’t sufficient. For example, when I tried a simple task like sorting the list, it would take several minutes to process the operation. I would literally click ‘Sort’ and then go and work on another task for a while.
A cool way to tease your email content is to syndicate your content on a platform like Medium or LinkedIn Pulse. Or, team up with an influencer in your space to help spread the word about the awesome content you’re sending through email. The more you promote yourself to relevant communities and groups, the more likely you are to keep your email list growing and growing.

ashley.. try benchmark as well. the differences i can see, for me anyway are we have 3 products, so want a different company name to show for each, and if they opt out i wanted the option of which list they want to opt out of, even if i send them letter A from list A, but maybe they are also in B and C, they might still want letters from b and c just not A, benchmark and i believe aweber does this. benchmark also allows you to set up a whole load of detailed surveys as well which is cool. mail chimp, if someone opts out of one list the lists are not linked in anyway so then you have to manually check them out of the other lists, and have to assume they want out of all with out giving them the option to chose in and out of what lists.

Finally, you can optionally include “automations” with your broadcast. Automations are a simple way to automatically add or remove tags when your subscribers do certain actions, like open the email or click on specific links. Adding and removing tags are important when creating segments, or subscriber groups, and triggering automated email campaigns.
