Ok, so cold outreach for B2B direct sales.
That’s one of the areas of sales & marketing that I have zero experience in, as I’d put that one 90% in the sales category.
That being said, check out Alex Berman’s YouTube channel, he has lots of great info on cold emails to get leads, and once you have leads you can set an appointment to sell whatever it is that you want to sell. If you haven’t got a product, again I suggest looking at affiliate offers, as there are still lots of things that apply to a B2B setting. Web hosting/IT services, etc. It really depends on your knowledge as it’d need to be something you understand well enough to sell.
Robert Cialdini reportedly learned sales by applying for entry level sales jobs and just doing the training… again and again, with different companies, to learn every angle of the craft.
As for networking, there are lots of books that help with networking for this purpose, most of the advice geared toward real estate agents would be applicable too.
