How to use it

The hack

before you switch on an AI SDR, split your account list into tiers and let the tool send only where a poor message costs you little.

The hack: before you switch on an AI SDR, split your account list into tiers and let the tool send only where a poor message costs you little.

Split the list first

TierWhich accountsWhat AI doesWhat a person does
Tier 1The accounts that would change your yearResearches and summarisesWrites and sends every message
Tier 2Look-alikes of your best customersDrafts from facts you have checkedApproves each message before it goes
Tier 3The rest of the named listSends from templates you have approvedReads every reply and answers it

If your list is not tiered yet, do that before you buy anything.

Three guardrails before it sends anything

  1. An exclusion list. Load every Tier 1 and Tier 2 domain, every customer and every open deal as do-not-contact. Check it works by trying to add one of them.
  2. Approved facts only. Give the tool a short fact sheet about your company and tell it to claim nothing outside it. Read ten of its drafts against the sheet.
  3. A person on replies. Every reply goes to a named person the same day. A buyer who answers has earned a human.

Five questions for the vendor

Questions to send before a demo

Questions to send before a demo
1. Can I load an exclusion list by company domain, and does it apply to every campaign?
2. Can I require approval before sending for accounts I choose?
3. Where does the tool get the facts it uses about a company, and can I see the source for each line?
4. What does it do when a buyer replies: answer, hand over or book a meeting?
5. Whose domains and mailboxes does it send from, and who keeps them if we stop?

A two-week test on your own numbers

Run it on Tier 3 only, and count four things yourself. Do not accept the tool's dashboard as the result.

What to countWhere to find it
Messages with a wrong or unsupported factRead a sample of 50 sent messages against your fact sheet
Replies asking to stop, and complaintsYour inbox, not the tool's summary
Replies a person would call a real conversationRead every reply
Tier 1 or Tier 2 accounts touched by mistakeSearch the sent log for your exclusion list

If the last line is anything but zero, stop and fix the exclusion list before you go on.

Three mistakes to avoid

  1. Pointing it at your best accounts first because that is where the money is. Start where a mistake is cheap.
  2. Judging it on messages sent. Sending was never the hard part.
  3. Leaving replies to the tool. The reply is the first moment the buyer is paying attention.

Make it a habit: each time you add accounts to the list, tier them and update the exclusion list before the tool sees them.

Why this works on named accounts

An AI SDR treats every row the same, which is exactly right for a lead list and exactly wrong for an account list. On a lead list a poor message costs one contact out of thousands. On a named list it reaches a company you chose on purpose, where the same few people will hear from you again next quarter. So the decision is not whether to use an AI SDR. It is which accounts it may touch. Tier the list first and the answer is plain: automation at the bottom, people at the top.
