Proactiveness for Sales in B2B product.

It depends so much on the product and ICP as to which channel is most effective. I would suggest that the one common thread is going to be consistency. Work back from your goal to the number of touchpoints that you need to reach it, and then focus on that input rather than the goal that can look scary. Block time to ensure you do that consistently every day - there's a cumulative effect. As an example with a fairly typical B2B Sales funnel. Goal: 2 customers a month. To get that we need... 4 x demos 8 x discovery / intro calls 16 x replies 160 x opens 400 x emails. 400 emails / 20 working days = 20 personalised emails a day. So, to hit that, we need a process for quickly researching each prospect, templates we can adapt, and probably 3 hours a day blocked. Back when I was an SDR (fair few years ago) this was how I'd approach it. 20 emails a day is much less scary a task than 2 paying customers. (In reality, I'd suggest experimenting with different channels initially and when you see better returns from one, double down).
