Had a guy on a job in Arlington swear up and down that inside corner first was the only way and he would not let it go. We went back and forth so long his helper just started laying block the other way to shut us up. Funny thing is the wall came out fine either way, but try telling that to two stubborn masons. That guy still brings it up every time I run into him at the supply yard.

Keeps coming down to the list and the timing, not the email itself. Sixty emails to ops managers at mid size firms is crazy specific, that's the whole trick. If you blasted the same pitch to 600 random info@ addresses you'd get zero calls and a spam complaint. I've seen it both ways in my own work, same subject line, one list got 22 percent opens and the other got 3. Also week two matters, you probably hit them right when budget talks were happening. Do the same thing next quarter and you might get 4 calls instead of 14. That doesn't mean cold email is dead, it means it only works when you show up in front of the right 60 people at the right time.
