Authentic.

See here:  FCC to require phone carriers to authenticate calls by 2021If you use something like Callrail for tracking purposes and use their numbers for cold calling they are now showing up as "Spam Risk" on caller ID which has dropped the contact rate significantly. 

Thank you for being authentic in your response. and congrats on creating a new business. 

Actually handwriting the letters yourself will definitely get you a better response rate, as it feels more personal and authentic (because it is!).

Nike says it best when they say "Just do it".

It won't looks as authentic, but writing "looking forward to your call" 1400 times gets tiresome.

Do you see Nike cold calling?

I can see how if someone really needed to sell their house (which is the only way a sale will happen) then it shouldn't matter what my letter says... the seller would just look for the number and call.I just wanted to change it up since it seems like when I'm re-mailing the same letter to propects it looks less genuine due to the identical wording used... might make some people feel its "less authentic" and motivate them to call and ask to be taken off the list.

I have done a couple deals and purchased other courses and I believe his blueprint is the most authentic and not just a ploy to sell, but actually help people that is looking to further develop their business and scale.  

Well, sometimes they say "hell no" depending on how outrageous the price is.They will sometimes ask how the person came up with the number.Other times they may need to bring in an expert to authenticate the item or give their opinion on the value of the item.They also explain, when the person balks at their number, that they run a business, and have to make a profit, and have overhead, and that the person can take their item to auction, but it may sit several months, there's no guarantee to sell, the auction house will take 30-50%, whereas they can pay cash RIGHT NOW.
