AiSDR
An AI sales rep that researches leads from your HubSpot data and runs personalised email and LinkedIn outreach on a schedule, without a human sending each message.
What you'd use it for
Running ongoing, personalised cold email and LinkedIn outreach straight off your HubSpot data, without a human drafting or sending each message.
- Researches and messages leads pulled straight from your HubSpot or Salesforce records, without a separate list-building step
- Sends personalised email and LinkedIn outreach — connection requests, direct messages, InMail — on an ongoing schedule without a human clicking send
- Replies to prospects within 5 to 10 minutes, or routes replies to a human in co-pilot mode
- Tracks LinkedIn signals such as post engagement, profile visits and keyword mentions to time outreach, from the Explore plan up
- Runs AI-scripted phone call steps through an Aircall integration, with automated follow-up after each call
The verdict
AiSDR actually sends outreach on a schedule once it is set up, rather than just drafting messages for a human to send. That autonomy has a cost beyond the sticker price: Explore and Scale run on quarterly, paid-in-advance contracts rather than the cancel-anytime billing Solo gets, and Explore, at $900 a month, is the real floor for anything beyond a single seller. It suits a founder or small sales team that already runs HubSpot and is willing to hand a live sending identity to a machine; it is a poor fit for anyone who wants to approve every message before it goes out.
What it costs
| Tier | Price | For | Includes |
|---|---|---|---|
| Solo | $250/mo ($2,400/yr billed annually) | A founder or solo seller who wants pipeline without hiring an SDR. | 200 AI-researched contacts/month, 1 user, 1 domain, 3 mailboxes, 1 LinkedIn account. |
| Explore | $900/mo ($8,640/yr billed annually) | Proving outbound can fill the pipeline before scaling it further. | 800 AI-researched contacts/month, unlimited users, 2 domains, 6 mailboxes, 5 LinkedIn accounts, HubSpot data monitoring. |
| Scale | $2,500/mo ($24,000/yr billed annually) | Treating outreach as a dependable pipeline channel. | 2,500 AI-researched contacts/month, unlimited users, 6 domains, 18 mailboxes, 20 LinkedIn accounts, native two-way Salesforce sync. |
| Enterprise | Speak to sales | Organisations with custom volume or integration needs. | Negotiated terms beyond the Scale tier. |

What you need to start
- An active HubSpot account to sync leads from (Salesforce sync is available only on the Scale plan)
- A Gmail or Outlook mailbox to connect, or acceptance of the mailbox AiSDR sets up for you
- A quarterly, paid-in-advance commitment on the Explore and Scale plans; Solo is the only month-to-month tier
Under an hour to connect HubSpot and get a first campaign drafted, but mailbox warmup on Explore and Scale can add up to 30 days before AiSDR is sending at full volume.
Your first run Once you connect HubSpot and share one real sent email for Ami AI to learn your voice, it drafts a full outbound campaign for you to review the same day; live sending only starts once your mailboxes finish warming, which is fastest on Solo's single domain.
Where it breaks
The billing toggle is easy to read backwards. AiSDR's page defaults to Quarterly, and quarterly is not the discounted option -- it is simply the contract cadence, billed monthly with payment in advance. The 20% discount belongs to Annual, and it is already reflected in the annual figures in the rows above ($250 a month against $2,400 a year, which is exactly 20% off twelve months at $250). The other thing the toggle does not tell you is that the cadence differs by plan: Solo is month-to-month and cancellable, while Explore and Scale are quarterly contracts you cannot leave mid-term. A fully-managed onboarding add-on costs an extra $2,500 a month on top of any tier.
First entry in this reference. There is no previous check to compare it against.
When not to use it
Not for anyone who wants to review outreach before it sends: autopilot is the default and co-pilot review is an opt-in extra. Sending cold email and LinkedIn messages under your name puts CAN-SPAM and GDPR compliance, and the risk of burning a sending domain, on you rather than on AiSDR. Also a poor fit below an existing HubSpot subscription, or for a two-person team unwilling to commit to Explore's quarterly, paid-in-advance contract.
AiSDR takes the job title literally: it researches a list of leads against your HubSpot data, writes personalised outreach for each one, and sends it — email and LinkedIn — on an ongoing basis, rather than acting as a writing assistant that only drafts messages for you to send.
The pricing scales with what you are actually buying more of: contacts researched per month, plus how many domains, mailboxes and LinkedIn accounts you’re sending from — which matters for deliverability, since spreading volume across more sending identities keeps any single one from looking like a spam operation.
What you are trading for the lower price
Solo, at $250/mo, is genuinely built for one person running their own pipeline — one domain, three mailboxes, no room to add a second seller without upgrading. That is a real constraint, not a teaser tier: a two-person founding team will hit its limits within the first week.
Explore is the tier most companies actually land on, since it is the first one with unlimited users and enough sending infrastructure (2 domains, 6 mailboxes) to run outreach without one account carrying all the volume.
Where it sits against the alternatives
Against a tool like Smartwriter.ai, which personalises messages but leaves you to send them, AiSDR goes a step further: it is closer to an SDR you manage than a copywriter you paste from.
