You might want to look at AWeber as it has a Blog Broadcast feature which can automatically email out new posts for you. They can confirm subscribers if you want which I would recommend and they have all the statistics you could want.

I would avoid having people subscribe via FeedBurner. I actually recently wrote a blog about why not. Here’s an excerpt of the relevant section.

What’s the Point? People Can Already Subscribe to My RSS Feed

The difference between subscribing to a RSS feed and an email list is quite substantial. A RSS feed is tied directly to the posts on your blog. The feed is only updated when you create a new post. If your reader subscribed to the feed via email then they may see it in their inbox. Otherwise, the reader would have to open their feed reader to see your new posts. Which do you think gets more attention, the inbox or a feed reader?

Even if your reader subscribed to the RSS feed via email all they would ever see is your latest posts. This is where an email list separates itself. You can send your list subscribers an email about anything at anytime. You can promote a product launch, special coupon or an upcoming webinar. Basically, you don’t have to create a blog post just to get into your subscriber’s inbox.

If you decided to shutdown your site and start a new one all your RSS subscribers, even those subscribed via email would be lost. With an email list you could continue communicating with your subscribers and even use it to promote your new site.

@kristi-hines @howwhowhen I have an email/autoresponder system, and do plan to include posts in my eZine. Ideally I am looking for a way to automate sending to those who want the posts without having to create the email content separately. It would be great to have them signup (and let them also know they are opting in for email) but trying to figure out automating the blog post sending is my sticking point.

I have one not-fully-automated way in mind that uses my existing forms & email system but the blog content sending isn’t fully automated, so requires some manual work. I might choose to go that route, but just thought I’d see if anyone had other ideas without serious custom development.

@kristi-hines I’m using the Striker theme and looking for a good post subscriber button that will allow me to create my own messages to subscribers possible include images, too. I want one that prevents spam – they have to enter the letter in a box -.  I want to also capture their email addresses for future email campaigns /newsletters.  Which of the three you mentioned Aweber, Mail Chimp or, Get Response would be most suitable?.  As always, thanks for your help

I would definitely encourage you to check out Aweber. I switched from MailChimp a little over a year ago and it’s the best things that’s happened to my email list.

Aweber has been the best I have used. It has lots of features that grows with you and your business. You ad social media to a post or not. It has rss feed to your post, tracking for every click that come through. Lots of great great tracking to see how you are doing.http://stayconnected.aweber.com/
