There is definitely a difference between "cold calling" and "spam" when it comes to b2b solicitation. I'm sure pharmaceutical reps show up to doctors offices often unannounced, but is that IRL spam or would a doctor miss out on useful information (even if the noise ratio is high) if this weren't a common practice?
To me it boils down to whether the information could be useful or if the person sending the emails is running a spray and pray type of campaign. If you have built a useful product that could make a business more productive, you shouldn't be shunned for letting people know about it, especially if they have published their email address and gave an impression that they were interested in hearing about it.
