Start from the beginning

Part one contains no AI at all. You cannot evaluate software that replaces an SDR without knowing what an SDR does, what one costs, and why the role exists — and every page in this category assumes you already do.

Part 1 — Outbound Fundamentals

What the job is, what it costs, and why it works when it works. No AI in this part at all, you cannot evaluate something that replaces an SDR without knowing what an SDR does.

1.1What Is an SDR? The Role, Explained ProperlyA sales development rep books meetings so a closer never has to prospect. That division of labour only pays off above a specific deal size.1.2How Much Does an SDR Cost? $134K a Year, ItemisedPublished estimates of a fully loaded SDR run from $134,000 to $154,000. The spread is a disagreement about which costs count.1.3Why Cold Email Goes to Spam (and How to Fix It)You can write the best cold email of your life and have it filtered before a human sees it. Deliverability is the layer underneath it all.

Part 2 — AI SDRs

What the software actually automates, what it does not, and how the pricing models compare against the human cost established in part one.

2.1What Is an AI SDR? What It Automates, and What It Does NotAn AI SDR sources prospects, writes sequences and sends them. Three things decide whether that produces meetings, and the software controls one of them.

Part 3 — Voice Agents

How a voice agent is assembled, where the latency budget goes, what a minute costs, and the compliance rules that apply the moment you dial out.

3.1How AI Voice Agents Work, Layer by LayerSpeech in, text, a decision, speech out, down a phone line. Every voice agent is those four layers, and the hard part is not any of them individually.
