Hand an AI SDR the tasks that have a checkable right answer: account research, first-draft writing, reply sorting, CRM logging and follow-up timing. Keep with a human the tasks that carry judgement, money or a relationship: approving what goes out, pricing, objections, and the first live conversation. The split is by task, not by role. In a small team, one person plus an agent does the work of a larger outbound desk.
Why split by task and not by role?
A sales development rep (SDR) does 15 or more different things in a week. Some are mechanical. Some are not. Asking "should we replace the SDR?" mixes them. Asking "which of these tasks can a machine do and prove it did?" does not.
Use three tests for each task:
- Is there a checkable right answer? A reply is either an unsubscribe or it is not. Whether a prospect "seems warm" is a judgement.
- What does a mistake cost? A wrong CRM field costs minutes. A wrong price in writing costs margin.
- Is it reversible? A draft can be edited. A sent message cannot be unsent.
Tasks that pass all three go to the agent. Tasks that fail any one stay with a person, or go to the agent with a person approving.
Which SDR tasks should an agent take?
| Task | Hand to agent? | Check that applies | |---|---|---| | Find the right contact at an account | Yes, with a source link | Person confirms the role on a sample | | Write one specific fact about the account | Yes | Fact must cite a page the reviewer can open | | Draft the first email or message | Yes, into a review queue | Person approves before send | | Time the follow-up | Yes | Rule: step, gap, daily cap | | Sort replies by type | Yes | Weekly sample against human labels | | Log the touch and the reply in the CRM | Yes | Actor and time on every entry | | Chase a no-reply at day 3, 7 or 14 | Yes, draft only | Person approves the send | | Remove unsubscribes everywhere | Yes, immediately | Suppression list checked before each send | | Produce the weekly activity report | Yes | Numbers come from the log, not from the model |
The agent is strongest where work is high-volume and low-judgement. Our live outreach system for an insurance brokerage writes one checkable first line per contact at about S$0.02 an email, and sorts a reply at about S$0.01. A person doing the same research at ten minutes a contact cannot match that, and does not need to.
Which tasks should a human keep?
- Approving first sends. The message carries your company name. A named person reads the draft and the cited fact, then approves or edits.
- Handling objections. An objection is rarely about the stated reason. "We already have a provider" can mean price, a bad past experience, or politics. A person asks a second question. An agent tends to answer the first one.
- Price and terms. The agent quotes from an approved list. It does not negotiate. See why sales agents need hard limits on discounts.
- The first live call. Tone, silence and what is not said are not in the data.
- Complaints and sensitive replies. Anything mentioning a dispute, a regulator or a data request stops the workflow and reaches a named person.
- Deciding which accounts matter. Territory and priority reflect strategy. The agent can rank on the rules you give it. You decide the rules.
What does the work look like with both?
Take a five-person team with one SDR. The week before and after, in tasks:
Before: the SDR researches 40 accounts, writes 40 emails, checks the inbox, labels replies, updates the CRM, chases the quiet ones. Roughly all of the week.
After:
- The agent researches and drafts all 40 overnight.
- The SDR spends a short block each morning approving, editing or rejecting drafts.
- The agent sorts replies as they arrive and raises the interested ones to the SDR with the thread attached.
- The SDR calls, qualifies and hands to an account executive.
- The agent logs every step.
The SDR's time moves from typing to talking. The number of accounts covered goes up because the cheap part got cheaper, not because the person works faster.
What are the risks of handing over too much?
Four failure modes recur.
Confident errors from stale data. If the CRM says an account is a customer and it churned, the agent writes as if it is. Fix the data first, and have the agent cite where each fact came from.
Volume that damages your domain. An agent can send more than your reputation can bear. Google's email sender guidelines ask senders to keep the spam rate in Postmaster Tools below 0.10% and never reach 0.30%. Cap sends per inbox per day and watch the rate weekly.
Skipped consent rules. Singapore's Spam Control Act 2007 and the PDPC's Do Not Call Registry guidance apply to automated sending as they do to manual sending. Hong Kong, Indonesia and Malaysia have their own rules. Put the checks in the system, not in a policy document.
Hostile text in replies. A reply can contain instructions aimed at the agent. The agent should treat reply text as data, never as commands. Background in prompt injection in business AI agents.
For the wider risk of an agent that sends in your name, see is it safe to let an AI agent send emails to customers.
How do you decide when to loosen the approval step?
Measure first. After four weeks of reviewing every draft, count how often the reviewer changed anything. If a draft type is approved unchanged nearly every time, you can move it to sampled review: the person checks one in five and the agent sends the rest. If edits are frequent, tighten the prompt or the source data before loosening anything.
Never loosen for price, terms, complaints or first contact in a new market. Those stay with a person.
Where KYN fits
KYN builds the agent and the review queue together, inside a cloud account in your name. Agents run under their own restricted accounts. Every action is logged with the actor. Outbound messages, money and deletions wait for a named person. For an insurance brokerage we built outreach, a reply desk and a group-benefits comparison that produces a client PDF at about S$0.03 per comparison.
The first 14 days are a review of your current stack and interviews with your team. A full build ships in under 90 days. Pricing is a one-off build fee and a retainer of at least twelve months, quoted after the review. See sales systems and pricing.
Frequently asked questions
Can an AI SDR fully replace a human SDR?
For the mechanical tasks, yes. For approving sends, handling objections and holding the first call, no. Most SMEs get more from one person with an agent than from either alone.
What should a small team automate first?
Reply sorting and CRM logging. They have a checkable answer, a low cost of error and an immediate saving in time. Drafting comes second, with approval on every send.
How do you check an AI SDR is doing the job well?
Take a sample of 100 replies, label them by hand, and compare with the agent. Track misses on interested replies and unsubscribes in particular. Also track the minutes a reviewer spends per 100 drafts.
