As with most ESPs, you’ll need to certify that any list you upload is permission-based and conforms with the provider’s anti-spam policies. AWeber takes this a step farther than some. You will need to enter the source of the email list when you upload it, and AWeber requires confirmed opt-in for all addresses. This means your first email will have to be a request for your subscribers to confirm their subscriptions. Anyone who doesn’t confirm can’t be on your list. (AWeber does allow some exceptions to this rule if you have a list that has already gone through confirmed opt-in 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.
