Fun metaphor:
Sending a cold email campaign is kinda like giving out free fish taco samples. 🐟🌮
(An individual cold email = a fish taco.)
In order to have an actual “taco sample to give out,” you first need to put all the ingredients together.
These are the “cold email taco ingredients:”

Quality matters with ALL of these ingredients.
Higher quality almost always = better results.
BUT!
Quality comes at the price of time and $.
So we don’t actually want the “highest quality possible. “
What we want instead is the sweet spot of the “highest quality possible in the least time & money possible.”
A.K.A. “80:20 Good.”
