Many autoresponder providers will recommend that you require a double optin procedure. That means that people not only have to sign up for your list in the first place, but they also have to click a link in their email that confirms they want to receive messages from you.
While this might seem like a hassle, it certainly does prevent complaints and other problems for you. On the other hand, sometimes these confirmation emails get lost in the shuffle or people do not understand what they are or what to do with them.
Make sure that people understand what they are supposed to do with the confirmation email by providing simple, clear instructions after they sign up.

You may also wish to provide screenshots or video right after they sign up. This simple step can greatly increase your double optin subscribers.
