The Blog Broadcast is Aweber’s term for the automatic emails that get sent out every time you publish a blog post. They are separate from the other automatic follow ups that you send out. The great thing about Aweber is that you can choose to send a hundred follow ups or none, automatic blog broadcasts or manual blog broadcasts, etc. It is all up to you. For example, here on Blog Tyrant I send out all my updates automatically to my subscribers as well as the occasional email newsletter with a few tips and specials.
You can turn off confirmed opt-ins in AWeber, but it’s not recommended, which your story verifies. One of the reasons that AWeber has a high deliverability rate is the lack of spam going out via the service. So when importing a list it does suck to have to send out a bunch of emails, but it keep their service up and going, and our emails being delivered.
With Aweber however, this is not that easy to do. With Aweber, each and every one of your subscribers is tagged with a message number which indicates which followup emails they have received already. To prevent a subscriber from receiving a specific followup email, you must set the subscriber’s message number to be higher than the email sequence number.
Before you can send AWesome emails with AWeber, you'll need someone to send it to. The easiest way to begin building your list is to import contacts that have opted-in to your email list, or gave you permission to send them emails. These could be subscribers you've emailed from another provider, or a list of contacts that you've built through your business.
