What I was trying to get across (and perhaps I didn’t make myself clear here, my fault), is that there are also other equally excellent services. I mentioned MailChimp as someone mentioned they’d like a mail list manager but couldn’t afford AW. MC is free for the first 1000 subscribers, and I think for a large proportion of entrepreneurs, that is enough to get started (more than enough, probably).
What I like about Mailchimp is that you can setup autoresponders such that only a subset of your email list will receive your follow-up emails based on when they signed up for your newsletter. For example, if I only want recent subscribers from the last month to receive one of my autoresponders, I can simply specify this using MailChimp’s autoresponder interface.

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.
I just wanted to send you an email and give you a big thank you. I am busting my butt trying to build an online business, and I carry a very strong interest in marketing (I'm a graphic designer, so I guess it could go hand in hand). I'm never sure who is who, I can't tell who I'm listening too or buying from or who created what, but I feel you create and offer some of the best quality products for prices that really do meet my budget. And a BIG THANKS for all of the effort and quality content you provide. - Slade Julius
Variations of “Hello {!firstname_fix}” have become the norm in email marketing, not the outlier. Because of that, it’s losing its effectiveness. You can still use name personalization, but you also want to think about going a step further. At AWeber, we recommend segmenting your audience and sending each segment tailored messages with unique subject lines.
Using the Personalize dropdown, you can insert custom snippets like your subscribers first name, or sign up date, and AWeber will automatically insert that data specific to each subscriber if we have it. If you collect first name, for example, you can send an email that says Hello Tom, or Hello Mary, or Hello John, depending upon who you’re sending to.
