How much does marketing automation cost?
The contact-count model, what each tool charges at scale, and how to avoid paying for contacts you cannot email.
Marketing automation costs anywhere from $9 a month to more than $15,000 a month, and the gap is not really about features. It is about how each tool meters your account. Most platforms charge by contact-list size, so the teaser price on the homepage describes the smallest account they will sell you, not the bill you pay once your list grows. You pay for the model, not the logo: a contact-count tool gets expensive as your audience grows, a send-volume tool stays cheap if you store a big list but email it rarely, and the enterprise names attach four and five-figure setup fees before you send a single email. This guide gives you the real cost at scale for the eight tools people actually shop, the traps that inflate the bill quietly, and a Lab Score view of where the money goes furthest.
The short answer, by stage
If you just want a number, here is the honest range for 2026 in the United States, the figures most buyers land on once you account for list size and billing terms. The detail behind each is in the sections below.
| Your stage | Typical monthly cost | What you get for it |
|---|---|---|
| Solo or small business (about 500 to 1,000 contacts) | $9 to $20 | Entry tier of HubSpot Starter, ActiveCampaign Starter, Mailchimp Essentials, or Brevo Starter |
| Growing SMB (about 5,000 contacts) | $59 to $205 | ActiveCampaign Plus or Pro ($79 to $205), Mailchimp Standard (~$100), Klaviyo email (~$100), GetResponse ($59 to $69). Brevo is cheaper if you send rarely. |
| Mid-market, full automation (10,000+ contacts) | $200 to $800+ | HubSpot Professional at $800 a month plus a one-time $3,000 onboarding fee; ActiveCampaign or GetResponse roughly $200 to $600 |
| Enterprise (custom quote) | $1,250 to $15,000 | Salesforce Account Engagement (Pardot) $1,250 to $4,000, Adobe Marketo Engage ~$1,500 to $10,000+, HubSpot Enterprise $3,600 plus $7,000 onboarding, all before implementation |
The real question is never “how much does it cost,” it is “how much does it cost at the list size I will reach next year.” A low number at 1,000 contacts tells you almost nothing about your bill at 25,000.
The three pricing models (this is the whole game)
Almost every cost surprise traces back to which of these models a tool uses. Learn the three and you can predict your bill before you ever open a pricing page.
- Contact-count (subscriber) model. You pay for the size of your stored audience, and the price jumps at fixed thresholds. This is the dominant model and the source of most traps. HubSpot, ActiveCampaign, Mailchimp, GetResponse, Marketo, and Pardot all work this way.
- Email-volume (send-based) model. You pay for emails sent per month, and stored contacts are unlimited or close to free. Brevo is the clearest example. This is the cheaper model for a large list you email infrequently.
- Active-profile model. A stricter version of contact-count. Klaviyo bills every contactable profile regardless of whether the person opted in, a change it made in February 2025. A shopper who left an email at checkout and never subscribed still counts against your tier.
There is a fourth wrinkle: the seat-plus-contact hybrid. HubSpot stacks per-seat fees on top of the contact tier, so adding a teammate and adding contacts both raise the bill, independently. Most other tools include their users in the plan.
| Model | You pay by | Cheapest when | Used by |
|---|---|---|---|
| Contact-count | Size of stored list | Small list, frequent sends | HubSpot, ActiveCampaign, Mailchimp, GetResponse, Marketo, Pardot |
| Email-volume | Emails sent per month | Large list, infrequent sends | Brevo |
| Active-profile | All contactable profiles, opted in or not | Clean, fully opted-in list only | Klaviyo |
Real cost at scale: the same list, six tools
This is the table the homepage prices do not want you to see. Below is what each contact-count tool actually charges as one list grows from 1,000 to 10,000 contacts, using verified 2026 figures. ActiveCampaign rows show the annual-commitment monthly rate; its month-to-month rate runs higher (for example Starter is $19 monthly versus $15 annual at 1,000 contacts).
| Tool and plan | 1,000 | 2,500 | 5,000 | 10,000 |
|---|---|---|---|---|
| ActiveCampaign Starter | $15 | $39 | $79 | $149 |
| ActiveCampaign Plus | $49 | $95 | $145 | $189 |
| ActiveCampaign Pro | $79 | $149 | $205 | $375 |
| Mailchimp Standard | ~$20 | ~$60 | ~$100 | ~$135 |
| Klaviyo (email) | $30 | ~$70 | $100 | $150 |
| GetResponse Marketing Automation | $59 | $69 | ~$120 | ~$160 |
A few honest notes on this table. ActiveCampaign Pro at 1,000 contacts shows $79 on annual billing in some sources and $99 as a list rate in others, so treat that cell as the low end of a range. Mailchimp publishes its tiers through a calculator that localizes currency, so the tilde-marked values are corroborated from 2026 review sources rather than scraped live; verify the exact cell in-app. Klaviyo bills monthly only with no annual discount, while ActiveCampaign and GetResponse cut roughly 18 to 20 percent for an annual commitment. Brevo is missing here on purpose: it does not bill by list size at all, which is the point of the next section.
Why Brevo can be the cheapest tool you are not pricing
Brevo (formerly Sendinblue) charges by emails sent per month and stores unlimited contacts for free. That single choice flips the math for anyone with a big list and a light sending habit. If you hold 50,000 contacts but email them twice a month, a contact-count tool charges you for all 50,000 every month, while Brevo charges only for the ~100,000 sends.
| Brevo plan | Starts at | Contacts stored | Notable |
|---|---|---|---|
| Free | $0 | Unlimited | 300 emails per day (about 9,000 a month) |
| Starter | $9 | Unlimited | Logo removal is an extra $9 a month on this tier |
| Business | $18 | Unlimited | Adds landing pages, A/B testing, unlimited automation, advanced reporting, phone support; logo removal included |
| Enterprise | Custom | Unlimited | Negotiated |
The catch keeps Brevo honest: per-email costs add up at high volume, and a duplicate contact in two lists is still billed twice. Brevo wins for storage-heavy, send-light senders and loses for daily-blast operations. That is the model talking, not the brand.
HubSpot: the seat-plus-contact bill, fully loaded
HubSpot Marketing Hub is the tool whose real cost diverges most from its headline, because it stacks two meters and a mandatory onboarding fee. Starter looks like a $9 product. Professional is where serious automation lives, and it carries a one-time $3,000 onboarding fee in year one that is not optional.
| Plan | Monthly (annual rate) | Included | Extra seats | One-time onboarding |
|---|---|---|---|---|
| Free | $0 | 2 users, 2,000 sends a month | n/a | None |
| Starter | $9 / seat | 1,000 contacts, 5,000 sends | per seat | None |
| Professional | $800 | 3 seats, 2,000 contacts, 20,000 sends | $45 / mo | $3,000 |
| Enterprise | $3,600 | 5 seats, 10,000 contacts, 200,000 sends | $75 / mo | $7,000 |
Watch the contact overage. On Professional, exceeding your included contacts auto-bumps you to the next block (the Pro blocks step at 5,000, 12,000, and 17,000), and the first jump from 2,000 to the 5,000 block adds roughly $250 a month. Starter scales in 1,000-contact increments; Enterprise in 10,000-contact blocks. A realistic first-year Professional bill is therefore $800 a month plus $3,000 onboarding plus any seat and contact overage, far from the pricing-page number.
Klaviyo and the active-profile meter
Klaviyo is built for ecommerce and prices on profiles, not just subscribers. One feature of its pricing quietly raises bills: every paid tier has identical features, so you pay more only because the list grew, never because you gained a new capability.
| Profiles | Email plan | Profiles | Email plan |
|---|---|---|---|
| 250 (free) | $0 | 25,000 | $400 |
| 500 | $20 | 50,000 | $720 |
| 1,000 | $30 | 100,000 | $1,380 |
| 5,000 | $100 | 250,000 | ~$2,300 |
| 10,000 | $150 | Above 250,000 | Custom |
The free tier covers 250 profiles, 500 emails a month, and 150 SMS credits. There is no annual discount and no setup fee for self-serve signups. The traps are specific: Klaviyo counts every contactable profile including checkout emails that never opted in; a 90-day suppression lock means un-suppressing a contact stops you from re-suppressing them for three billing cycles; SMS, WhatsApp, reviews, and analytics are separate add-ons; and auto-downgrade is off by default, so your plan will not shrink when your list does unless you toggle it.
The enterprise tier: where the setup fee dwarfs the subscription
Adobe Marketo Engage and Salesforce Marketing Cloud Account Engagement (Pardot) publish almost nothing about price, because both are sold through quotes tied to your database size. The subscription is only half the cost; implementation is the other half, and for these two it is large.
| Platform and tier | Subscription | Implementation | Billed on |
|---|---|---|---|
| Pardot Growth | $1,250 | Varies | Contacts and features |
| Pardot Plus | $2,500 | Varies | Contacts and features |
| Pardot Advanced | $4,000 | Varies | Contacts and features |
| Pardot Premium | $15,000 | Varies | Contacts and features |
| Marketo (Growth to Ultimate) | ~$1,500 to $10,000+ | $10,000 to $50,000+ | Total database records |
Two things matter here. Marketo bills on total database records, so every contact you store counts, not just the ones you can email, and a bloated database raises the subscription too. And Marketo implementation through a certified partner runs $10,000 to $50,000 or more, paid once but before launch. These figures are reseller and review estimates, since neither vendor offers self-serve pricing; the real number is whatever you negotiate.
The cost traps that inflate the bill quietly
Every figure above assumes a clean account. Here is what actually happens to real accounts, drawn from across the tools in this guide.
- Paying for dead weight. Unsubscribed, bounced, inactive, and never-opted-in contacts count toward your tier in most contact-count tools (Mailchimp, Constant Contact, Klaviyo) until you manually purge them. Cleaning the list cuts bills 20 to 40 percent.
- Duplicate billing. The same email in two lists or audiences counts as two billable contacts in Mailchimp and Brevo.
- Tier-jump cliffs. One contact over a threshold can raise the whole bill, from $10 to $30 a month on GetResponse to roughly $250 a month on the HubSpot Professional jump from the 2,000 to the 5,000 block.
- Mid-cycle auto-upgrade. Hit a higher tier at any point in the month and you are billed at the higher tier for the month (GetResponse, Constant Contact, HubSpot). GetResponse bills on your highest active subscriber count during the month.
- Onboarding and implementation fees. HubSpot adds $3,000 (Pro) or $7,000 (Enterprise) one-time; Marketo and Pardot implementation runs $10,000 to $50,000+.
- Seat fees on top of contact fees. HubSpot charges $45 to $75 per seat per month beyond the included seats.
- Add-ons billed separately. SMS, WhatsApp, a dedicated IP, logo removal, advanced analytics, and higher CRM tiers are line items, not inclusions.
- Suppression locks. Klaviyo’s 90-day re-suppression rule forces three billing cycles of payment on a contact you tried to remove.
- Auto-downgrade off by default. Plans do not shrink with your list unless you turn it on (Klaviyo).
The pattern across all ten: the meter ratchets up on autopilot and ratchets down only when you intervene. Put a quarterly list-cleaning task on the calendar. That one habit is worth more than any plan choice.
Annual versus monthly, and the Lab Score view
Annual billing cuts the rate by roughly 18 to 20 percent on ActiveCampaign, GetResponse, and HubSpot, and locks you in for the year. Klaviyo offers no annual discount, billing monthly only, which keeps you flexible but never cheap. The annual-versus-monthly call is a trade between price and the freedom to leave, and the right answer depends on how confident you are in the tool.
This is where the RealCostLabs Lab Score comes in. We score each tool from 0 to 10 on value at scale, deliverability, automation, ease, and support, and the consistent finding is one the pricing pages bury: the cheapest tools are often the most satisfying. Across independent ratings, the lower-cost platforms hold their own or win. ActiveCampaign sits at 4.5 on G2 across roughly 14,500 reviews and 4.6 on Capterra. Klaviyo rates 4.6 on both G2 and Capterra. HubSpot, the most expensive of the mainstream set, rates 4.4 on G2 and 4.5 on Capterra, with its most common criticism being exactly that the price scales fast and advanced features sit behind costly tiers. Mailchimp rates 4.3 on G2 and 4.5 on Capterra, and the recurring verdict is that users outgrow its automation. Paying more does not reliably buy you a happier team. It usually buys you a bigger list and a longer feature list you may not use.
FAQ
What is the cheapest way to start with marketing automation?
The free tiers are real. HubSpot Free gives you 2 users and 2,000 sends a month; Brevo Free allows 300 emails a day with unlimited stored contacts; Klaviyo Free covers 250 profiles. When you outgrow free, the entry paid tiers run $9 to $20 a month at 500 to 1,000 contacts (HubSpot Starter, ActiveCampaign Starter, Mailchimp Essentials, Brevo Starter). Brevo Starter from $9 is the cheapest credible paid entry point if you store a large list.
Why did my bill jump when I barely added contacts?
You crossed a tier threshold. Contact-count tools price in fixed blocks, so one contact over a line bumps the whole account to the next block: $10 to $30 a month on GetResponse, and about $250 a month on the HubSpot Professional jump from the 2,000 to the 5,000 block. Several tools also bill on your highest contact count at any point in the month, so a temporary spike can charge you at the higher tier for the full cycle.
Does a bigger list always mean a bigger bill?
On contact-count and active-profile tools, yes, unless you clean the list, because unsubscribed, bounced, and non-opted-in contacts usually still count. On Brevo’s send-volume model, no: contacts are free and you pay only for emails sent, so a large list you email rarely stays cheap. This is the biggest lever in the category, and the reason the same audience can cost wildly different amounts across tools.
How much does enterprise marketing automation really cost?
Plan on $1,250 to $4,000 a month for Salesforce Account Engagement (Pardot) from Growth to Advanced, with Premium at $15,000; and roughly $1,500 to $10,000+ a month for Adobe Marketo Engage. Then add implementation, which is $10,000 to $50,000 or more for Marketo through a certified partner. HubSpot Enterprise is $3,600 a month plus a one-time $7,000 onboarding fee. Neither Marketo nor Pardot publishes self-serve pricing, so the real figure is negotiated against your database size.
Is paying more worth it for better deliverability or features?
Not reliably. Independent ratings show the cheaper tools matching or beating the expensive ones: ActiveCampaign and Klaviyo both rate around 4.5 to 4.6 on G2 and Capterra, while HubSpot at 4.4 on G2 draws its loudest criticism for fast-scaling price and features behind costly tiers. Most of what a higher tier buys is room for a bigger list, not a better outcome. Match the tool’s model to your list size and sending habit first, and let price follow.
