You can get a list of a few thousand easily and in one month. And it isn't using PPC. It will cost about $500 - $1,000 up front, but it is hands free auto-pilot. I teach it and don't share it. So we will call it MethodX.
+ You create a nice looking video squeeze page. Ask for name and email.
+ In the video give them something free and cool, and direct them to the optin form. Show them on the video exactly how to do it. Tell them to fill out the form, then they will need to login to their email account and click the verification link. After they click the verification link (you now have a double optin lead) they will get the "free and cool" thing you told them about. You can either have the double optin verification link take them to a thankyou page with what they wanted on it, or email it to them. Just make sure you walk them through all of it in the video.
+ Once your page is setup, you use "MethodX" to send your targeted auto-pilot traffic to the page for a whole month.
The point of the page is to scrub those who initially fill out the form. Kind of like a "turn them off those really interested will still follow through". So the ones who actually go through the double optin sequence, are COMPLETELY targeted and highly interested. You now have turned off those who will be useless on your list, and will have a very high stat mailing list.
You may be missing out of a thousand or two of email addresses, but your list will be very powerful and have soaring open and click rates. Give them some free content for about 2-3 weeks. Maybe something twice a week, for 2-3 weeks. Building trust and they get to know you and think your a cool guy. So they are looking forward to your next email because they are wondering what your going to give them for free next. After your 2-3 weeks of giving them free shit, slip in your SELL! Don't be pushy, but put an urgency on it like "I am only selling 500 copies and if you buy RIGHT NOW, you will get bonusx free!". A whole do it now, or you will be missing out on this amazing extra.
Enjoy more money that month, than a 9-5.
Continue methodx every month, or every couple months. A fresh lead source is vital. If you get a bulk amount of leads and stop bringing new leads into your funnel, you are marketing in a well. That well will dry up!
