AiSDR does one thing whole: you hand outbound to an agent and it runs. That suits some teams and it doesn't suit others. Cheaper cold email, better data, more channels, or a rep who stays in the loop are all reasons to shop around.
Below are twelve tools, with what each costs and who it fits. Every price came off the vendor's own pricing page this month.

Your list is the problem
You already have a way to send. What you don't have is a reason to believe the people receiving it care this week. That's the part we built: intent signals first, messages second.

An autonomous agent fits you
With nobody writing outbound today, a full agent like 11x or Agent Frank buys you the most time. Come to us instead if you'd rather fix who gets contacted before you automate the contacting.

Buy sending, not an agent
Deliverability and cost are your constraints, so Instantly or Smartlead will serve you better than any AI SDR. Come to us instead when the sending works and the replies still don't.
Table of contents
Four picks before the long list, by where outbound hurts.
Gojiberry
Best when the problem is who you contact, not how fast. Flat rate per account.
Apollo.io
Best when you want a database and sequencing on one bill, with a rep driving.
Instantly
Best when the job is email volume at the lowest monthly cost.
Reply.io
Best when email, calls and social share one cadence, with a human approving.
Five reasons come up, price being the loudest. The quieter one is data: median job tenure in the US runs 3.9 years, with 22% of workers in post under a year, so a chunk of any list you inherited already points at people who've moved on.
Our guide to B2B sales automation covers where each layer sits in the stack.
These twelve don't do the same job. Three are agents running outbound end to end, seven are platforms where a rep drives, one is a set of parts you wire together. The first starts earlier, by deciding who's worth a message. The order runs from closest swaps to cheapest pieces.
How we built this list. Every price was read off the vendor's own pricing page in September 2026. We ignored the figures circulating in comparison posts, several of which describe a model that doesn't exist any more, and where a vendor gates its numbers we say so.
What you won't find is a scorecard of reply rates. We haven't run one campaign on one list through all twelve, and a made-up percentage would be worth less than this sentence admitting it. We pay for every plan ourselves, no vendor read this first, and Gojiberry is our product, which is why it's first and why we say where it loses.
Gojiberry watches for the moment a company starts looking, then reaches the people inside it. It tracks 30+ buying-intent signals across socials and the web, scores them against your ICP, and runs the outreach. You're buying the list; sending is what happens next.

Pro is $99 a month for the account, not per seat, with two agents and up to 1,800 prospects contacted. There's a free start.
We won't pretend to be the hands-off agent AiSDR sells. We make sure the 400 people you contact are worth contacting: GTE Localize booked 100+ meetings that way, and you can read how.
11x runs Alice, an agent that researches accounts, writes the touches, sends them, and handles what comes back. Outbound happens without anyone opening a sequence builder.

Growth starts at $3,750 a month on annual billing. Pro and Enterprise aren't published, they're quoted.
It removes more manual work than anything here, and it's a first-year commitment costing what a junior rep does.
Artisan bundles a 300M+ database with Ava, an agent that builds sequences and runs them. Autopilot sends alone, copilot waits for approval.

The Employee package lists around $600 a month billed annually, and you won't see volume pricing without a call.
One vendor instead of three. Then you notice the annual term, and that what's published is a floor.
Agent Frank pulls prospects from a 500M+ index, writes in your tone, sends and follows up. It works in 20+ languages, which counts once your market stops being English-only.

Frank starts at $599 a month billed quarterly for 1,000 active contacts, and you'll get two months free annually.
No buying signals sit underneath, so Frank writes beautifully to whoever you've pointed him at. Plenty of teams take that trade.
Reply.io has run sequences since 2014, with Jason AI added on top. Email, calls, SMS and social share one cadence, and a rep signs off.

Email Volume opens at $49 per user a month, Multichannel at $89, plus channel add-ons. Jason AI's separate, from $500.
Human oversight is where it wins. Per-seat arithmetic is where it loses.
Regie.ai stacks AI agents on a 220M+ database, with sequencing, intent prioritization and a dialer. It's aimed at sales floors rather than founders.

AI SEP lists at $180 per user a month with a ten-seat minimum, so the real floor's $1,800 a month.
The seat minimum decides this one. Below ten reps with nobody owning ops, the contract costs more than the pipeline it'd find you.
Amplemarket puts contact data, buying signals and sequencing behind one login, with an AI copilot reviewing campaigns. Teams that move here retire three or four subscriptions.

Startup is $600 a month for two seats, annual billing only. Growth and Elite aren't published at all.
Nothing here folds more tools into one contract, and nothing here asks a two-person team for a bigger bet before they've tested it.
Apollo is the first subscription many small teams buy: database, sequences, dialer and CRM sync in one workspace. A rep drives all of it.

Basic runs $49 per seat on annual billing, Professional $79, Organization $119 with three seats minimum. Pay monthly and you'll add 20%.
It's the cheapest route to data and sending on one subscription, if somebody has the hours to work it.
Instantly exists to get cold email delivered at volume. Unlimited sending accounts and warmup come with every plan, so the bill tracks sends rather than headcount.

Growth is $47 a month for 5,000 sends, Hypergrowth $97, Light Speed $358. The lead database isn't bundled, it's billed apart.
Nothing here moves more email for less money. Then you add credits and the CRM module, and $47 lands nearer $125.
Clay is a table where each column calls a data provider or an AI agent. 150+ sources sit behind it, and nothing sends until you attach a sender.

Launch is $185 a month with 2,500 data credits and Growth is $495. New customers can't buy the old tiers.
Ceiling is the highest here. Floor is a person who wants to build.
Smartlead sells deliverability: unlimited mailboxes, warmup, inbox rotation and a master inbox, pointed at agencies and high-volume senders.

Base is $39 a month for 2,000 leads and 6,000 sends, Pro $94, Unlimited Smart $174, Prime $379. You aren't charged per inbox.
Nothing here protects a sending reputation better, and nothing here cares less whether the list deserved the send.
Snov.io folds an email finder, verifier, drip campaigns and a light CRM into one cheap subscription. Seats are unlimited on every paid plan.

Starter is $39 a month for 1,000 credits and Pro starts at $99 for 5,000. Social automation isn't included, at $69 per slot.
Price is the whole argument. A three-person team gets a full outbound loop for less than one Apollo seat, and depth is what they pay for it.
Monthly starting prices, taken from each vendor directly in September 2026. Seat minimums and annual-only terms are flagged where they move the floor.
For warm, high-intent leads, it's us. Claiming otherwise would be odd, since finding them is why Gojiberry exists. Wispra now sources 60% of its weekly demos from intent signals, which you can see broken down here.
For a fully autonomous rep, 11x if the budget and security review are there, Artisan if you'd rather one vendor carried the data. On budget, Instantly wins on the sticker and Snov.io once you count seats. For all-in-one prospecting, Apollo, whose free plan lets you find out before committing.
For multichannel with oversight, Reply.io. For personalization, Clay, if somebody enjoys building. For deliverability at volume, Smartlead. For a bigger SDR floor, Regie.ai past ten seats.
Want better leads before you start sending?
Gojiberry surfaces prospects who are in-market this week and enriches them before they reach your sequences.
Get warm leads →Four questions settle most of it, and the last decides less than people expect.
Your stack, ICP and volume matter more than any feature table. Volume without targeting is also the shortest path to Google's 0.3% spam complaint threshold, which bulk senders have had to stay under since February 2024. Our walkthrough on automating sales prospecting orders those decisions.

Smartlead's Base plan and Snov.io's Starter both open at $39 a month, and Instantly's Growth at $47. None of the three includes an agent. Gojiberry's Pro plan is $99 for the whole account, with nothing charged per seat.
A team of two to ten wants flat pricing and no seat minimums, which points at Gojiberry, Instantly, Smartlead and Snov.io. Regie.ai's ten-seat minimum and Amplemarket's annual-only contract rule both out at that size.
Not the whole job. Agents handle research, first touches and follow-ups well, and they're weak on objections. Teams that get value from them move reps toward closing rather than cutting heads.
Instantly or Smartlead, and it's close. Smartlead's rotation and master inbox are more mature, Instantly is cheaper at entry. Both make you bring a list, and B2B contact data decays around 2.1% a month.
Reply.io if you want a rep approving each step, Gojiberry if you'd rather the agent coordinate email and social itself. Reply's add-ons push the real per-seat cost near $187, so run that against your headcount.
Apollo, Clay and Snov.io all run free tiers, and each one's a demo rather than a working plan. Gojiberry starts free without a card, AiSDR has no trial at all. Our roundup of email outreach automation tools covers each tier.
