AiSDR: The Pricing, and the Mailbox Arithmetic Behind It
AiSDR publishes domains, mailboxes and contact volume next to every price. Those numbers are worth more than the prices, because they let you check the sending plan.
AiSDR publishes three tiers: Solo at $250 a month, Explore at $900 and Scale at $2,500, with an annual state showing a twenty percent reduction. Each tier states its contact allowance, domain count, mailbox count and LinkedIn account count, which is a level of disclosure the category rarely offers.
Key takeaways
- AiSDR's published tiers are Solo at $250 a month, Explore at $900 and Scale at $2,500, with annual figures of $2,400, $8,640 and $24,000 on the same page.
- Each tier publishes its infrastructure: Solo lists 1 domain and 3 mailboxes for 200 contacts a month, Scale lists 6 domains and 18 mailboxes for 2,500.
- Seats stop being the meter above the entry tier, where both larger plans state unlimited users and the metered resource is contact volume.
- The page states that safely readying multiple inboxes for volume takes more than thirty days, which is the vendor conceding that month one is infrastructure rather than pipeline.
Reviewed and updated August 15, 2026
AiSDR publishes something almost nobody else in its category does. Alongside the price of each plan, its pricing page states how many domains, how many mailboxes and how many LinkedIn accounts come with it, and how many contacts a month the plan is sized for. Fetched on 15 August 2026, the entry tier reads 1 domain, 3 mailboxes, 1 LinkedIn account and 200 contacts a month. The top published tier reads 6 domains, 18 mailboxes, 20 LinkedIn accounts and 2,500 contacts a month.
Those numbers are worth more than the prices beside them, because they are the only published figures in this category that let an outsider check whether the sending plan is physically sound before signing anything.
A disclosure before going further. RevenueFlow runs cold outbound as a service and is paid on attended qualified meetings, so we compete for budget with tools like this one, though not in the same shape. Everything below comes from AiSDR's own pages as they rendered on 15 August 2026.
What AiSDR sells
AiSDR sells an AI sales development representative: software that builds a list, researches each contact, writes the first touch, sends it across email and LinkedIn, handles the reply, and books a meeting. The published positioning names an agent that runs the campaigns and a strategist layer that proposes and builds them.
The platform-wide claims on the pricing page are a database described as 300 million or more leads globally, plus Sales Navigator data for real-time LinkedIn information, two-way HubSpot sync on every plan with Salesforce sync from the top tier, and reply handling described as arriving in five to ten minutes or running in a copilot mode where a person approves first.
The sending mechanics are published in unusual detail for this category: creation of new mailboxes, ongoing domain warmup, three bounce checks before sending, domain health tracking, and automated inbox rotation. Those are the things a sending programme actually runs on, and it is a genuinely good sign that they appear on a pricing page rather than in a sales call.
What the tiers cost and what they carry
Three tiers are published, and each one states its infrastructure alongside its price, which is what makes the table below unusual.
- 200 AI-researched contacts a month
- 1 user
- 1 domain, 3 mailboxes, 1 LinkedIn account
- Two-way HubSpot sync
- Turnkey email setup and warmup
- Billed monthly, described as cancel anytime
- 800 AI-researched contacts a month
- Unlimited users
- 2 domains, 6 mailboxes, 5 LinkedIn accounts
- LinkedIn signals including post engagement and profile visits
- Per-campaign managed service available at $149 a campaign
- Quarterly contract, marked most popular
- 2,500 AI-researched contacts a month
- Unlimited users
- 6 domains, 18 mailboxes, 20 LinkedIn accounts
- Native two-way Salesforce sync and website visitor tracking
- Fully managed service available at an additional $2,500 a month
- Quarterly contract
Two structural details are easy to miss. The seat count stops being a variable above the entry tier: Explore and Scale both say unlimited users, so this is not a per-seat product and the thing being metered is contact volume. And the contract term differs by tier. Solo runs month to month; Explore and Scale carry quarterly contracts, which the page explains on the grounds that inbox warmup alone takes more than thirty days before a programme can send at its intended volume.
That explanation is honest and it is also the most useful sentence on the page. It is the vendor stating, in its own words, that the first month of any deployment at volume is infrastructure rather than pipeline.
It also reframes the entry tier. Solo is the one plan that runs month to month, and the page attributes that to having fewer mailboxes to warm, which lets it start sending sooner. Read as a product decision that is a sensible ramp. Read as a budgeting fact it means the cheapest plan is also the only one you can leave inside a quarter, so a team using Solo as a trial before committing should be clear that it is testing the message and the list rather than testing the volume, because the volume behaviour of the larger tiers is a different system.
One further note on the published rates. The pricing page carries a monthly and an annual state on the same document, and the annual state is described as a 20 percent reduction. The annual figures beside each plan are consistent with that: the plan quoted at $2,500 a month appears at $24,000 for a year, against $30,000 if the monthly rate simply ran for twelve months. Quote whichever state you are actually buying, because both sets of numbers are live on one page and they are not the same price.
The arithmetic the disclosure makes possible
The following figures are our own arithmetic on AiSDR's published numbers rather than anything the vendor states, and they are illustrative of the shape rather than a benchmark.
Our arithmetic: 200 contacts across 3 mailboxes
Our arithmetic: 800 contacts across 6 mailboxes
Our arithmetic: 2,500 contacts across 18 mailboxes
Our arithmetic: $2,500 divided by 2,500 contacts
The first three numbers are the interesting ones. They rise as the plans get larger, which is the direction you would expect, and they stay inside a range that reads as deliberate rather than accidental. A per-mailbox monthly load in that region is a conservative sending posture. Most of the damage in this category comes from a plan that quietly assumes a much higher figure, because volume that arrives through too few mailboxes is the most common cause of a dead deployment, which is the reasoning behind holding far more sending capacity than the plan needs.
The cost-per-contact figure is the one to be careful with. It is capacity, not outcome. A contact is somebody who receives a message, and no published figure anywhere in this category bridges from contacts to replies or from replies to meetings. That gap is not AiSDR's failing specifically. A software vendor sells capability and has no business defining your qualification bar. It is a warning about how the comparison is usually framed, because a team weighing this against an agency or a hire is comparing a tool that produces activity against services that produce meetings, and the comparison means nothing until somebody has written down what a meeting worth having looks like.
AiSDR pricing questions the page does not settle
The pricing page is unusually forthcoming and still leaves three things open, and all three are contract questions rather than product ones.
The first is what happens to unused volume and to overage. A plan sized at 800 contacts a month does not say whether an unused allowance carries forward or whether exceeding it triggers a charge, a block or a conversation.
The second is what the managed-service add-ons include. Explore lists a per-campaign managed service at an additional $149 per campaign and Scale lists a fully managed service at an additional $2,500 a month, which doubles that tier's cost. What work sits inside each of those, and who owns the outcome, is the difference between a tool purchase and a services purchase.
The third is whose domains carry the sending reputation. The page describes creating new mailboxes and warming domains, and the plans are counted in domains, which reads as domains dedicated to you. Confirm that in writing, because in this category the consequences of volume accrue to whoever owns the domain, and it is the single most expensive thing to discover after the fact.
- Yes: Whether the monthly contact allowance is a cap, a target or a billing threshold
- Yes: What unused volume does at the end of a month
- Yes: Who owns the sending domains and therefore the reputation consequences
- Yes: What the managed-service tiers actually do, and who owns the outcome
- Yes: Whether the approval mode is workable at your contracted volume
- No: Treating the contact allowance as a forecast of meetings
- No: Starting at your target volume rather than ramping into it
Where we run this differently
One published feature deserves a direct answer rather than a silent disagreement, because it is a real product capability and we do the opposite.
The plans include configurable omnichannel sequences with unlimited touchpoints and contextualised follow-ups based on lead behaviour. That is what the category sells and it is what most buyers want. We run one message per campaign for cold outbound, with no thread replies and no bumps.
The reasoning is mechanical rather than moral. A sequence exits on a reply, so every step after the first is delivered exclusively to people who already saw a message from you and chose not to answer, which is the population most likely to file a spam complaint. The reply lift from those later touches is measured inside the campaign, and the reputation cost is paid by the sending domain across every campaign running on it, so the unit of measurement and the unit of damage are different objects. What replaces the follow-up is a new campaign with a genuinely different premise rather than a reminder. The full argument, including what the position costs us, is in email sequence software.
The relevance to a volume-priced plan is direct. A tool metered in contacts has every incentive to make the allowance easy to consume, and the cheapest way to consume it is to reach the same people more often. Whichever product you buy, decide that question deliberately rather than letting the default decide it.
Who it fits
The model suits a team with a proven offer and a defined ICP that wants more volume without more headcount, and that has somebody who will own the output rather than assuming the software owns it. The published mailbox counts and the honesty about warmup time suggest a vendor that understands the sending half of the problem, which is not universal in this category.
It fits less well if you have not yet booked meetings manually in your market, because every AI SDR is a machine for executing a hypothesis faster and a weak hypothesis reaches more people sooner. It also fits less well if your volume ambitions run well past the top published tier, at which point you are in a custom conversation and the published transparency stops helping.
If you are placing this against the category rather than against one vendor, the capability boundary and the named landscape are in AI SDR, the human comparison is in outsourced SDR pricing, and the question of which seat to staff is in SDR vs AI SDR vs GTM engineer. Our own terms are on the free campaign page.

Frequently asked questions.
Frequently asked questions- How much does AiSDR cost?
- Its pricing page published three tiers on 15 August 2026: Solo at $250 a month or $2,400 a year, Explore at $900 a month or $8,640 a year, and Scale at $2,500 a month or $24,000 a year. Managed service is extra, at $149 a campaign on Explore and $2,500 a month on Scale.
- What does an AiSDR contact allowance actually mean?
- It counts people the system researches and contacts in a month, which is capacity rather than an outcome. No published figure in this category bridges from contacts to replies or from replies to meetings. Establish in writing whether the allowance behaves as a cap, a target or a billing threshold, and what unused volume does.
- Is AiSDR contract length negotiable?
- The published structure differs by tier. Solo is described as billed monthly and cancel anytime. Explore and Scale carry quarterly contracts, which the page attributes to inbox warmup taking more than thirty days before a programme can send at its intended volume. That explanation is about deliverability rather than lock-in.
- Why do the published mailbox counts matter more than the price?
- Volume through too few mailboxes is the most common cause of a dead outbound deployment, and almost no vendor in this category publishes the ratio. Because AiSDR states contacts, domains and mailboxes per tier, an outsider can check whether the sending plan is physically conservative before signing anything.
