The best AI sales agent: what the label covers, and which tools earn the name
You built the company on a craft. Clients arrive because someone who knows you told someone else, and that has worked well enough that hiring a salesperson never seemed necessary. Then a quiet quarter arrives, the referrals thin out, and at eleven at night you type something like best AI sales agent into a search box.
I run Klientee, which is one of the products that comes back on that search. Read the rest knowing that. What follows is mostly about how to tell these tools apart, and one section is about when not to buy mine.
One word, three different products
The phrase covers at least three categories that do not overlap much. I am describing what each is commonly sold as. For what any single product does today, read the vendor's own page rather than me.
Sending platforms. You bring the list of people and the text of the message. The software manages mailboxes, spreads sends over the day, handles follow-ups and routes replies. Instantly, Smartlead, Saleshandy, lemlist and Woodpecker are sold mainly on this ground. They are infrastructure. Useful infrastructure, and the cheapest tier of the whole market.
Writing and data layers. These produce message text, or find and enrich contact records, and are usually billed by credit rather than by seat. Regie.ai and Explee sit here. They solve part of the work and hand the rest back to you.
Products that claim the whole job. Artisan, 11x and AiSDR present themselves as a member of staff rather than a tool: something that finds people, writes to them, and follows up. This is where the word agent is used most literally, and where the monthly prices are highest.
A reader who does not know which of the three they are looking at will compare a $32 sending tool against a $2,500 managed service and conclude that one of them is dishonest. Neither is. They are answering different questions.
The question that separates them
Before an email can exist, three decisions have to be made.
- Who receives it.
- What it says, specifically about that person's company, in a way that is true.
- When it goes.
Ask any vendor one question: what do I have to give you before the first email can leave?
If the answer includes a list of contacts, the product is not making decision one. If it includes a template, it is not making decision two. Almost all of them make decision three only in the mechanical sense of spacing messages through the working day.
This is not a trick question and it is not an accusation. A sending platform is honest about being a sending platform. But the whole reason you searched for an agent is that you do not have a list, you do not want to write the messages, and you were hoping to buy the judgement rather than the plumbing. The question tells you in one sentence whether that is what is on sale.
For Klientee the answer is a website address. It reads your site, works out who pays you and why, and shows you that reading with an extract from your own pages behind every claim, before any account exists. That is the part I can describe first hand, and the part you can check in two minutes without giving me anything. Whether the reading is right about your business is a judgement only you can make, which is exactly why it comes first and free.
The prices I could read, on 29 September 2026
On 29 September 2026 I loaded each vendor's public pricing page in a headless browser, waited for it to render, scrolled, and read the visible text. Prices checked on 29 September 2026. If one of these is wrong or has changed, tell me and I will correct it.
What I could read:
- Smartlead: $32, $59 and $78 per month, with add-ons priced separately at $59, $39 and $29.
- Saleshandy: on annual billing, $34, $76 and $149 per month, billed $408, $912 and $1,788 per year. On monthly billing the same tiers read $41, $99 and $189.
- Regie.ai: tiers at $0, $41, $49, $125 and $150. A free tier exists.
- Instantly: $47, $97 and $358 per month.
- Explee: credit based rather than seat based. The page offers $30 to try it, shows prices from $1 to $15, and repeats lines reading from $5 per 1k and from $10 per 1k.
- AiSDR: "start at $250/mo". Figures seen: $250, $900 and $2,500, plus $149 per managed campaign and $2,500 per month for a fully managed service. The page also shows from $349/month, from $94/month and from $59/user/month.
- Klientee, which is mine: $149, $349 and $749 per month per site. No credits, no per action billing, no multiplication by the number of people in your company.
Four pages did not give me a figure. On Artisan, 11x, lemlist and Woodpecker, the page either blocked automated reading or showed no price without interaction, such as a demo request or a toggle. The honest statement is the narrow one: I could not read a public price on those pages on that date. That is not the same as saying they do not publish prices, which I did not establish, and it says nothing about whether the products are good.
There is a longer version of this pricing exercise, covering the sending tools in more detail, in the best cold email software, judged on the prices I could actually read.
What the shape of the price tells you
Read past the number to the unit. Per seat means the bill grows when you add colleagues, even colleagues who will never open it. Per credit means the bill grows with volume, and quietly encourages you to send more in order to feel that you are getting value. Per campaign means a human is doing some of the work, which is worth paying for, but it is a service, not software, and it will behave like one.
The unit is a better predictor of your twelve month cost than the headline figure. It also predicts the behaviour the tool will nudge you toward.
Volume is the wrong dial for your company
Most of this market is built for a sales team that measures activity. You are not that. Your reputation is the only asset you have that competitors cannot buy, and it lives in a market small enough that people talk.
Some of the people you would write to respond to cold email by asking your provider about you, asking your data protection officer where the address came from, and contacting the regulator. You know this temperament because you share it. You delete these messages yourself.
So the buying criterion that matters is not how many messages per month a plan allows. It is how narrow the tool is willing to be, and whether what it sends would survive being forwarded to a peer with the comment "look what I got". If you cannot imagine surviving that forward, the volume allowance is irrelevant. For the line between a legitimate first approach and spam, I wrote a separate piece: what is a cold email, and what separates it from spam.
What a referral does, and which part software can take
It is worth naming why referrals work so well for you, because it explains what to buy.
A referral does three things in one movement. It explains what you are worth, using words you did not have to write. It reaches someone who resembles the person referring, which is why the fit is usually good. And it lands at the moment that person has the problem.
You can reconstruct the first two deliberately. The third one, the timing, is the part you have never controlled, and it is the whole reason a good firm can go hungry in a quiet quarter. Nothing is wrong with the work. You simply were not in the room on the week the budget appeared.
That is the only part of selling worth buying software for. Not more messages. Presence, repeated across a narrow and well chosen set of companies, so that you are occasionally there at the right moment. An agent that earns the name is one that decides who and what, so that the when stops depending on your calendar.
Where I am the wrong answer
Your order book is full and referrals are still arriving. Buy nothing this quarter. Prospecting tools bought out of anxiety get cancelled in month three, and the only lasting effect is that you trust the category less.
You already have a list that works and copy that converts. Then you need plumbing, not judgement. A sending platform at $32 to $47 per month does that job well and mine costs more for a problem you have already solved.
You want someone to run the meeting. No product in this article does that. Software can start a conversation. The call, the proposal and the price are yours, and if you dislike that part, a tool will not rescue you.
You sell to consumers, or your buyers are not identifiable as decision makers inside companies. None of this applies.
A sensible first month
- Take whatever free reading each vendor offers and judge it on whether it understood your business, not on how it looks.
- Ask each one the single question: what must I give you before the first email leaves?
- Write down the billing unit next to the price. Seat, credit, campaign or site.
- Pick one, run it for a full quarter, and judge it on the quality of the conversations, not the count of sends.
If after three months the only thing that has grown is the number of messages, you bought a sending tool with a better vocabulary. That is worth knowing, and it costs a quarter to find out rather than the six months and nine thousand euros that an agency costs.

Common questions
Is it legal to contact people this way in my country?
In Europe, business to business contact is generally possible, but you must be able to say where an address came from, explain why you are writing, and stop immediately on request. The rules differ between countries and are stricter in some than others, and outside Europe the framework is different again. Before you buy anything, ask the vendor in writing how they source addresses and how opt outs are handled, and check the answer against the rules that apply where you and your recipients are based.
What happens to my domain if this goes badly?
Poor sending practice can damage the reputation of the domain you send from, which affects ordinary client email too, including quotes and invoices. This is why many vendors set up a separate but similar domain for outbound messages and leave your main one untouched. Ask which approach a vendor uses before you sign, because recovering the deliverability of a main domain is slow and unpleasant work.
Do I need a CRM before any of this is useful?
No, not at the scale of a company with no salesperson. A spreadsheet and a calendar hold a quarter of conversations perfectly well, and buying a CRM first usually means spending two weeks configuring something before a single conversation exists. Add one when you are losing track of replies, not before.
How long before I know whether it worked?
Judge it at the end of a full quarter, and judge it on conversations rather than sends. A first month tends to be too short because the first messages go to whoever the tool chose without any correction from you, and the useful part is what you learn and adjust in weeks three to eight. If a vendor promises a specific number of meetings by a specific date, treat that as a warning rather than a commitment, since none of us controls when a buyer has the problem.
