Yep, I tend to agree.
I was just talking about this today with my team. Years ago, (he says from his Zimmer Frame), you would hear these amazing stories about direct mail success. A huge response and bazzillion dollars in sales generated.
But when you looked into it, it was a huge brand like Apple or Hilton Hotels or General Electric who had a huge budget to throw at it. Or, a one-in-a-lifetime SME who stumbled on a cracker of an idea.
And now, we hear stories of great 'link bait' that attracted a gazzillion hits - but it turns out to be the "Compare The MeerKat" campaign or something similar.
I'm not saying your shouldn't try. But whether you can pin your livelihood on it is doubtful IMO.
Just sayin'
