AiSDR Review 2026: The $250 Tier That Changed the Maths

The short answer

AiSDR is an AI sales development rep: it researches contacts, writes the outreach, sends it across email and LinkedIn, and handles replies. It is not a data tool you operate — it is closer to hiring someone, and it is priced closer to that too.

The important thing to know in 2026 is that the entry price changed. For most of this year the cheapest way to try AiSDR was $900 a month on a quarterly commitment. There is now a Solo tier at $250 a month with no contract. That is a 72% cut in the cost of finding out whether it works for you, and it is the single fact that should shape your decision.

What AiSDR costs right now

Annual prepay is a flat 20% off across all three — the arithmetic checks out exactly on every tier. There is no free trial, which matters more here than it would elsewhere, and we come back to it below.

Why most AiSDR pricing articles you will find are wrong

This is worth a section of its own because it will save you a bad comparison. Third-party pricing breakdowns published earlier in 2026 describe a different product: tiers named Explore, Grow and Enterprise; metering by messages sent and lead-search credits rather than by contacts researched; quarterly billing on every plan with no monthly option; and no entry point below $900.

AiSDR's own pricing page now shows Solo, Explore and Scale, meters by AI-researched contacts, and offers monthly billing on Solo. Two of the three price points — $900 and $2,500 — are unchanged and confirmed across every source, so those you can trust. Everything below $900 and every message-count figure you see quoted elsewhere postdates a structural change.

The practical instruction: read the vendor's pricing page yourself before you compare, and treat any AiSDR figure you find in a roundup as a claim with a date attached rather than a fact. That is good hygiene for any fast-moving category, and this one has moved.

The first number: $250

AiSDR does not offer a free trial. It never has. That means the entry price is not a subscription decision, it is the cost of the experiment — and until recently that experiment cost $900 a month on a quarterly contract, which is $2,700 before you learn anything.

Solo at $250 with monthly billing changes what kind of decision this is. One month of Solo is roughly a tenth of the old minimum commitment, and you can stop after it. For a founder deciding whether AI-written outbound produces anything at all in their market, that is the difference between a test and a bet.

The catch is that Solo is genuinely solo: one user, one sending domain, three mailboxes, one LinkedIn account. You cannot run a team on it and you cannot spread sending risk across domains. It is sized for exactly one person testing exactly one motion — which, for the purpose of finding out whether the thing works, is the correct size.

The second number: $1.00

Here is the calculation the pricing page does not do for you. Divide each tier's monthly price by its monthly contacts:

These are our calculations from AiSDR's published figures. Look at the spread: from the smallest plan to the largest — a tenfold increase in spend — the unit cost falls by twenty percent. Most software gives you far steeper volume discounts than that.

The implication is not that AiSDR is overpriced at the top. It is that you are not buying volume when you move up a tier. Solo to Explore is 3.6 times the price for 4 times the contacts. Explore to Scale is 2.8 times the price for 3.1 times the contacts. Both are close to linear, so the contacts are essentially the same price wherever you sit.

What you are actually buying when you move up

If not volume, then what? Infrastructure:

Domains and mailboxes are the constraint that actually governs cold outbound. Sending volume per mailbox has to stay low to keep deliverability intact, so more mailboxes across more domains is what lets you send more without landing in spam. Twenty LinkedIn accounts on Scale is a sales team's worth of profiles, not one person's.

So the honest way to choose a tier is to count seats, domains and mailboxes rather than contacts. If one domain and three mailboxes covers your sending, Solo's 200 contacts is probably the right ceiling anyway. If you need six mailboxes, you were always going to be on Explore regardless of how many contacts you use.

There are also managed-service add-ons: $149 per campaign on Explore, or a fully managed service at $2,500 a month on Scale — which doubles that tier to $5,000. Price those in deliberately rather than discovering them later.

The commitment structure matters more than the price

Solo bills monthly and you can cancel. Explore and Scale are quarterly contracts. That distinction is the real ladder, because it changes what a mistake costs: on Solo a bad month costs $250, on Explore a bad quarter costs $2,700.

This argues strongly for a specific sequence — start on Solo even if you know you will outgrow it. You will learn whether AI-written outreach lands in your market, whether the research quality holds up on your ICP, and whether replies are worth having, all before committing to a quarter. The 20% annual discount is real money, but it is money you should only spend after the question is answered.

Where AiSDR earns its keep

It suits people who have a working offer and no time to prospect. The research-plus-write-plus-send loop is the part that eats a founder's week, and handing that to software is a genuine reclaim rather than a marginal efficiency. If you know who you sell to and what makes them reply, AiSDR is executing a plan you already have.

It also suits teams testing several segments at once. Because the tiers give you multiple domains and mailboxes rather than just more volume, running three distinct motions in parallel is what the upper tiers are built for — and that is genuinely hard to do by hand without deliverability problems.

If you want to see whether the category fits before committing at all, the Solo tier is now a cheap enough way to find out that the question is worth asking. Pair it with a defined segment rather than a broad list — the research quality is what you are testing, and it only shows on a tight ICP.

Where it does not fit

If you do not yet know who your customer is, this will produce well-written messages to the wrong people, faster. AI does not fix a targeting problem; it scales whatever targeting you give it. Work out the segment first — our guide to generating B2B leads covers the groundwork this tool assumes you have already done.

If your budget is under about $200 a month, this is not your category. At $250 minimum with no free trial, AiSDR sits well above the tools that give you data and let you write the emails yourself. For lean operators, a data platform plus your own sequences is a fraction of the cost — we compared two of the main options in our Snov.io versus Apollo breakdown.

And if your outbound is inbound-adjacent — following up with people who already engaged with you — an autonomous SDR is the wrong shape entirely. Warm follow-up is a cheaper problem; something like a lead-magnet automation tool does that job for a tenth of the price.

Do this next

Count your mailboxes before you look at contacts. One domain and three mailboxes means Solo. Needing six means Explore, and the contact allowance is a side effect rather than the reason. This is the step most people skip, and it is the one that actually determines the tier.

Then buy one month of Solo, not a quarter of Explore. There is no free trial, so a single month is the cheapest possible experiment, and $250 buys you a real answer on research quality and reply rate. Run it against a narrow, well-defined segment where you can judge whether the messages are any good.

Finally, set the bar before you start. Decide now what a successful month looks like — a number of qualified replies, or one booked call worth more than $2,400, the annual cost of the entry tier. Start on Solo with that number written down, and let it rather than the annual discount decide whether you move up.

FAQs

Does AiSDR have a free trial?

No. There is no free tier and no trial. The cheapest way to evaluate it is one month of the Solo plan at $250, which bills monthly and can be cancelled.

Why do other sites say AiSDR starts at $900?

Because it did. Pricing summaries published earlier in 2026 describe a tier structure with no entry point below $900 and quarterly billing on every plan. The vendor's current pricing page shows a $250 Solo tier with monthly billing. Confirm on the pricing page rather than in a roundup.

Is annual billing worth it?

It is a flat 20% saving across all three tiers, which is real. But it is the wrong first move given there is no trial — take a month of Solo first, and only prepay a year once you have evidence the tool works on your list.

What does "AI-researched contacts" actually mean?

It is the metering unit on the current plans: 200 a month on Solo, 800 on Explore, 2,500 on Scale. Note that older third-party articles quote message counts instead, which is a different unit — another reason to confirm current terms directly.

What is the real difference between the tiers?

Sending infrastructure, not volume. The cost per contact only falls from $1.25 to $1.00 across a tenfold spend increase. What genuinely changes is users, domains, mailboxes and LinkedIn accounts — Solo gives you one of each where Scale gives you six domains and eighteen mailboxes.

How much is the managed service?

$149 per campaign on Explore, or a fully managed service at $2,500 a month on Scale — which doubles that plan's total cost to $5,000 a month.

Can I run a team on the Solo plan?

No. Solo is one user, one domain, three mailboxes and one LinkedIn account. Explore and above offer unlimited users. Solo is built for one person testing one motion.

Test the question before you buy the answer

The whole case for AiSDR now rests on one structural change: you can find out what it does for $250 instead of $2,700. That reorders the decision entirely — evaluate first, commit second, and let a month of real replies rather than a pricing table tell you which tier you belong on. Start with Solo, give it one clean segment, and judge it on what comes back.
