Ensuring requested opt-in email is delivered to subscriber inboxes is an increasingly difficult battle in the age of spam filtering. Open and click thru response rates can be dramatically affected by as much as 20-30% due to incorrect spam filter classification.

Confirming that the people who ask for your information have actually requested to be on your list is the number one step in the battle for deliverability. You should be using a process called confirmed opt-in or verified opt-in to send a unique link to the attempted subscriber when they request information. Before adding the person to your list they must click that unique link verifying that they are indeed the same person that owns the email address and requested to subscribe.

It should come as no surprise that an autoresponder is of huge importance to anyone running an online business, assuming it has all the necessary features and it's of the easy to use type. Having an automatic email response system setup that reliably responds to all incoming emails 24/7 and 365 days per year is without a doubt, a huge advantage in the world of Internet commerce.

There are many autoresponder programs available that can be setup on your own PC or on a local server. In addition to this type, there are also  autoresponders that are hosted on remote servers and generally these services cost money and in some cases, can become expensive.
