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).
AWeber has a strict and comprehensive anti-spam policy in order to keep its deliverability rates high. Upon signing up for an AWeber account, you must certify that your list is permission-based and meets the company’s anti-spam standards. In addition, before your first mailing, you will need to send a subscription confirmation to all your subscribers. Anyone who doesn’t confirm their subscription cannot be included on your list. (This is known as confirmed opt-in.) AWeber will sometimes make exceptions for lists which have already been through that process and have a proven history with another ESP.
Even if you've imported an existing list of contacts, you'll still want an easy way for new fans to join your email list. AWeber's sign up forms provide the perfect solution. Create a simple sign up form for your website, and if you don't have a site, we'll host it for you. Grab the link to your AWeber form and share it on Facebook, Twitter, LinkedIn, or wherever your audience is.
