I understand your concern and I share your frustration. I have send emails a few times where I'm clear about my budget and sales people tend to share the minimum commitment they expect, there isn't much lost by trying. Being on the other side of the table (running a SaaS requiring a call scheduled), I have do this because my SaaS its in an early stage, the call allows me to understand the customer needs and make a proposal when we are a good fit. In this particular case, it is hard to get a quote when I don't know the necessary customization that could be required. The call is a friction point that I'm trying to avoid by communicating example integrations and its prices in the landing page, still, making everything clear hasn't been simple. In short, asking by email could be a good idea.
