I am looking to sign up for an email service to collect mails and I am little confused as to how to go about doing it. I currently have an RSS subscriber base of around 1000. Most of them are email subscribers. Now, I know I can invite the existing RSS subscribers to my aweber (or another service) account. My question is once I have implemented aweber I will put the email subscription on the spotlight and won't be promoting RSS email much, do I still have the RSS email option available or is there a way I can integrate RSS updates into my email service? If so, is it advisable to link my site updates to my email service or will it make them unsubscribe? Or do I leave it such a way where people can subscribe to RSS email or my aweber email list depending on what they prefer. Will that make me lose some potential customers to my RSS email? Any feedback would be much appreciated.
