iContact is very serious about protecting the public from spam and has a strictly enforced set of terms and conditions. This means that there are rules to follow ensuring that contacts are happy to have you mailing them, have the option to unsubscribe at any time, are not subjected to inappropriate or misleading subject lines, and have access to your mailing address. In addition, they will flag up any issues in your emails which means it might be considered spam and blocked at the recipient’s end. If you send an email in breach of these conditions, iContact will block it, and guide you to some support to prevent this from happening in the future.
