Yellow Letters or Branded Letters?

[Alex Huegle]

I'm just wanting to get a straw poll on your guys' success and/or lack of success in comparing the use of yellow letters against branded letters. Arguably, 99% of what I see points to using the yellow letter format (which most likely answers my question), but I just can't wrap my head around it. I can't really find posts regarding the use of branded letters, so I thought I'd see if anyone out there is doing this. 

In theory, wouldn't someone in danger of losing their house/needing money trust a branded piece of mail offering a solution as opposed to a "hand-written" one? It just feels like a branded piece offers more legitimacy, but then again, I did my first deal off of a hand-written bandit sign, so maybe my theory doesn't stick in this arena.

In my mind, a letter with a unique envelope, logo, brief copy/clear messaging and call-to-action, and multiple ways to contact me make the most sense, but everything I'm reading points against that. 

Any advice from seasoned vets would be appreciated!
