Most marketing teams pick a CRM based on a feature comparison spreadsheet. They sit through demos. They pick the one with the nicest UI. Six months later, the team is exporting to spreadsheets for reports that should be automatic, and the attribution model looks like a conspiracy theory.

The problem isn’t the CRM. It’s that they bought a CRM for the wrong business model.

The CRM that wins for an ecommerce brand sending five million emails a month is completely different from the one that works for a B2B SaaS company with a 90-day sales cycle. The questions you ask before you buy matter more than any feature list.

This guide gives you the framework to figure out what you actually need, then recommends the best marketing CRMs for each situation.

What is a marketing CRM?

A marketing CRM manages customer relationships from the marketing side. It holds contact records, handles segmentation, tracks campaign activity, manages lifecycle stages, and connects your marketing effort to pipeline.

It’s different from a sales CRM in what it’s optimised for. A sales CRM is built around deals, pipelines, and close rates. A marketing CRM is built around audiences, engagement journeys, and the path from first touch to sales-ready.

Most modern platforms blur that line. HubSpot is both. Salesforce needs two hubs to cover both. That blurring matters when you’re deciding what you actually need and what you’re paying for.

Marketing CRM vs. marketing automation: what’s the difference?

This is the question that trips most buyers.

A CRM is a database of people, companies, and what they’ve done. Marketing automation is the engine that acts on that data: sends emails, scores leads, triggers workflows, personalises experiences.

The two are increasingly bundled. HubSpot’s Marketing Hub includes both. ActiveCampaign markets itself as a CRM with automation built in. Marketo pairs with Salesforce.

If someone is selling you “marketing automation” without CRM capability, you’ll end up with disconnected contact data. If someone is selling you a “CRM” with no automation, you’ll be doing everything manually.

Look for the pair.

The 5 questions to ask before you choose

Skip these and you’ll end up buying based on the best demo rather than the best fit.

1. What’s your business model?

This is the biggest fork in the road.

• B2B SaaS or professional services: You have a defined sales cycle, a buying committee, and a relationship to manage over months or years. You need strong contact and company records, lead scoring, and tight sales-to-marketing handoff.

• Ecommerce: You have high-volume, high-frequency transactions. You need deep integration with your store (Shopify, WooCommerce), segmentation by purchase behaviour, and automation triggers built around orders, carts, and browse data.

• Subscription apps (B2C SaaS): You’re running a product-led motion. Users sign up themselves, and your marketing CRM needs to connect to in-app behaviour (feature usage, activation events) to trigger the right messages at the right moment.

• Agency or services business: You’re managing client projects and relationships. The CRM is more of an account management tool. Deep automation is less critical.

Each model points toward a different set of tools.

2. How many users will be on the CRM?

CRM pricing scales fast. Most tools charge per seat, and the jump from Starter to Professional tier often unlocks the features that actually matter: A/B testing, advanced segmentation, multi-touch attribution reporting.

Calculate the total cost at your real user count before you fall in love with a platform.

Under 5 users: almost any tool works. 10 to 50 users: pricing differences become significant. Over 50: you’re in enterprise contract territory.

3. What’s your customer lifetime value?

High LTV (B2B contracts, premium subscriptions) justifies a more expensive CRM because attribution accuracy and pipeline quality have a direct impact on revenue decisions. If you’re closing £50,000 annual contracts, HubSpot Professional pays for itself in a single deal.

Low LTV, high volume (ecommerce, mobile apps) favours tools built for scale: Klaviyo, Customer.io. The margin per customer doesn’t support expensive per-seat models.

4. What channels do you market through?

Not all CRMs have equal channel depth.

• Email: Every platform has email. But open rates, deliverability reputation, and automation logic vary significantly between platforms.

• SMS: Klaviyo, ActiveCampaign, Braze. Most B2B CRMs add SMS as an afterthought.

• Social and paid ads: HubSpot connects to Meta and Google for lead capture. Most marketing CRMs don’t manage paid directly.

• Events and webinars: HubSpot, Marketo. Worth weighing if events are a core channel.

• In-app and push notifications: Braze, Customer.io, Intercom. Essential for subscription apps.

If you market across four or more channels, you need a CRM with native integrations to each. Otherwise you’re maintaining duplicate contact records across platforms.

5. Do marketing and sales need to share the same view?

If the answer is yes (and in B2B it almost always is), buy a platform with a genuine single contact record. HubSpot is the most common answer. Salesforce is the enterprise answer. Two-platform setups (e.g. Marketo for marketing, Salesforce for sales) work but require careful sync and create data lag.

If marketing and sales operate independently (most ecommerce, many B2C subscription companies), you can choose platforms optimised for each without worrying about handoff.

The best marketing CRMs by business model

Best for B2B SaaS (SMB to mid-market): HubSpot Marketing Hub

If you’re a B2B SaaS company with a defined sales cycle, a small to mid-sized team, and you want marketing and sales on the same platform, HubSpot is the default answer for a reason.

What makes it the right choice:

• Single contact record shared between marketing and sales: no sync, no data lag

• Strong lead scoring, lifecycle stage tracking, and attribution reporting

• Native connection to the CRM deal pipeline means you can trace marketing spend to closed revenue

• Accessible for non-technical teams with a low learning curve

• Deep integration with Salesforce if you eventually need the split

Where it falls short: HubSpot pricing escalates quickly once you reach the Professional tier, particularly at higher contact counts. The reporting is solid but not deep on multi-touch attribution. It’s built more for inbound than outbound; if your team runs heavy SDR sequences, other tools do that better.

Best for: 10 to 200 employee B2B SaaS or services companies with an inbound or mixed marketing motion.

Best for ecommerce: Klaviyo

Klaviyo is built from the ground up for ecommerce. It integrates natively with Shopify (and most other store platforms), ingests order and product data in real time, and gives you behavioural segmentation that’s actually useful: buyers who purchased X but not Y, customers whose last order was 90+ days ago, people who abandoned a checkout with a basket over £75.

What makes it the right choice:

• Real-time purchase, browse, and cart data from your store, not a delayed sync

• Segmentation engine built for high-volume transactional data

• Email and SMS in one platform with revenue attribution per campaign and per flow

• Benchmark data from a large ecommerce customer base, so you know immediately if your metrics are in or out of range

Where it falls short: Klaviyo is not a sales CRM. There’s no deal pipeline, no B2B contact management, no company records. If you’re a hybrid (ecommerce plus wholesale B2B), you’ll need a second tool alongside it.

Best for: Ecommerce brands, DTC companies, and omnichannel retailers.

Best for subscription apps and product-led growth: Customer.io

If you run a product-led growth motion, user onboarding sequences, or subscription lifecycle campaigns, Customer.io does things HubSpot and Klaviyo don’t: it connects to in-app events and sends messages based on what users actually do inside your product.

What makes it the right choice:

• Event-driven automation: trigger messages based on custom product events (user activated feature X, reached milestone Y, went inactive for 7 days)

• Strong API means your developers can push any data point into the platform

• Multi-channel: email, push notifications, SMS, and in-app messages all from one canvas

• Priced on message volume rather than contacts, which suits subscription models with large free-user bases

Where it falls short: Customer.io requires more technical setup than HubSpot or ActiveCampaign. Non-developers will feel the friction. The reporting layer is less polished.

Best for: B2C SaaS, subscription apps, any company where in-app behaviour drives the marketing trigger.

Best for agencies: GoHighLevel

Agencies have different needs from most CRM buyers. You’re managing multiple client accounts, not one. You need white-label capability, sub-account structure, and a tool that can run campaigns across 20 different clients without everything bleeding together.

GoHighLevel was built for this. It’s a full marketing stack (CRM, email, SMS, landing pages, forms, booking) in a multi-account wrapper. Agencies can charge clients for access and resell the platform at a margin.

Where it falls short: The product experience is not the cleanest, and integrations with enterprise tools are limited. If your clients use Salesforce or have complex B2B workflows, GoHighLevel will hit its ceiling.

Best for: Marketing agencies managing multiple SMB clients.

Best for small teams on a budget: ActiveCampaign

ActiveCampaign gives you genuine marketing automation (visual workflow builder, conditional logic, lead scoring) at a price point that doesn’t require director-level sign-off. It’s not the flashiest product on this list, but it works at affordable scale.

What makes it the right choice:

• Visual automation builder that’s accessible without training

• CRM and marketing on the same platform

• Strong email deliverability

• Pricing starts low and scales without a step-change

Where it falls short: The CRM component is limited compared to HubSpot. Company-level contact management is weak. If you’re growing fast, you’ll probably outgrow it within 18 months.

Best for: Small teams, consultants, early-stage companies, and founders who need real automation without enterprise pricing.

Best for enterprise B2B: Marketo (Adobe)

If you’re running an enterprise marketing operation with complex lead scoring models, multi-touch attribution requirements, ABM campaigns, and a large Salesforce instance, Marketo is the enterprise standard.

It’s not easy to use. It’s not easy to implement. And it costs accordingly. But it does things the mid-market tools don’t: sophisticated revenue cycle modelling, enterprise-grade compliance controls, deep Salesforce sync, and a reporting layer that holds up under CFO scrutiny.

Where it falls short: Implementation cost and timeline are significant. Budget for a dedicated marketing ops resource. This is not a tool you deploy on a Tuesday afternoon.

Best for: 500+ employee companies with dedicated marketing ops, a large Salesforce instance, and complex multi-channel campaigns.

Quick comparison table

All prices approximate, verified June 2026, annual billing where available. The starting price is rarely what you pay. Run the numbers at your actual contact count before making a final decision.

What does each tool actually cost?

The starting price is a floor, not a ceiling. Here’s what you’ll actually pay at common contact volumes.

HubSpot Marketing Hub

HubSpot charges on two axes: your plan tier and your marketing contact count. Both scale independently.

• Free: Up to 1,000 contacts. HubSpot branding on all sends.

• Starter: From $20/month (1,000 contacts). Removes branding, basic automation.

• Professional: From $800/month (2,000 contacts, 3 seats included). Full automation, A/B testing, attribution reporting. One-time onboarding fee of $3,000 required.

• Enterprise: From $3,600/month (10,000 contacts, 5 seats). Multi-touch attribution, customer journey analytics. One-time onboarding fee of $7,000 required.

Additional contacts add meaningfully to the Professional tier bill: every 5,000 contacts above the included allowance costs roughly $250/month. A B2B team at Professional with a 20,000-contact database should budget approximately $1,500–$2,000/month total.

Klaviyo

Klaviyo prices by active profiles — every contactable address in your account, including contacts you haven’t emailed recently. Since February 2025, all active profiles count toward your billing tier regardless of send activity.

SMS is billed separately on top of the base email plan. Regular list hygiene directly controls your monthly bill.

Customer.io

• Essentials: From $100/month (5,000 profiles, 1 million email sends/month). Entry point for SaaS lifecycle automation.

• Premium: From $1,000/month. Custom profile volume, HIPAA compliance, priority support, 90-day onboarding package.

• Enterprise: Custom pricing. Sales-led buying process.

ActiveCampaign

Priced per contact, annual billing:

Most teams with genuine lifecycle automation needs end up on Plus or Professional — the Starter plan caps automation actions per workflow, which is a hard constraint.

GoHighLevel

Flat monthly pricing regardless of contact count. No per-contact fees.

• Starter: $97/month (up to 3 client sub-accounts, unlimited contacts).

• Unlimited: $297/month (unlimited sub-accounts, white-label capability, API access).

• Agency Pro: $497/month (SaaS resell mode — charge clients for platform access under your brand).

Email and SMS usage is billed separately at cost through GoHighLevel’s LC services.

Marketo (Adobe)

All contracts are custom and sales-led. Adobe does not publish public pricing. Based on third-party buyer data:

• Growth tier: ~$895–$1,500/month, up to approximately 20,000 contacts.

• Select tier: ~$1,500–$3,000/month, up to approximately 50,000 contacts.

• Prime tier: ~$3,000–$6,000/month, up to approximately 75,000 contacts.

• Ultimate tier: $6,000+/month. Custom database limits, full feature access.

Implementation costs typically run 2–3x the annual licence fee. Budget for a dedicated marketing ops resource before signing. This is not a tool you deploy in a sprint.

Tools not in this guide: Braze, Iterable, and the enterprise engagement tier

The six tools above cover most companies reading this article. But two platforms come up frequently enough in evaluations that they’re worth understanding, even if they’re out of scope for most teams.

Braze

Braze is an enterprise customer engagement platform, not a CRM in the conventional sense. It does not manage deals or track pipeline. What it does is orchestrate real-time, cross-channel messaging at a scale and speed that mid-market tools cannot match. Mobile push, in-app, email, SMS, WhatsApp, RCS, and LINE — Braze has the broadest channel footprint in the category.

The numbers give you a sense of the scale it operates at: 7.8 billion monthly active users across its customer base, 25.8 trillion data points processed in 2025, and a single Black Friday/Cyber Monday period of 59.9 billion messages. Its customers include Deliveroo, the NBA, Goldman Sachs, Sephora, and Duolingo.

Pricing is custom and sales-led. Based on procurement data, contracts run approximately $30,000–$60,000/year at the entry tier, $100,000–$250,000/year at mid-tier, and $250,000–$1,000,000+/year at enterprise. Average contract value was $88,506 in 2026.

Who it’s for: Enterprise consumer brands where mobile engagement drives revenue, and where a dedicated technical team (SDK implementation, Liquid templating, data engineering) is available to run it properly.

Who it’s not for: Anyone without an enterprise budget and a dedicated marketing ops function. Implementation averages four months; some enterprise deployments run six to twelve.

Iterable

Iterable competes directly with Braze in the enterprise cross-channel category but sits at a slightly different point on the price and complexity curve. It’s more marketer-friendly — the journey builder UI, segmentation logic, and content management are generally rated as more intuitive than Braze’s. Its Nova AI agent, launched formally in April 2026, handles journey building, copy generation, and segment creation from natural language prompts.

Channel breadth is narrower than Braze (no LINE, less mature RCS), and at the very top of infrastructure scale Braze has a meaningful edge. But for enterprise and upper-mid-market brands where email is the primary channel and mobile is secondary, Iterable is the stronger fit.

Pricing is custom and enterprise-led. Based on procurement data, mid-tier contracts run approximately $4,000/month at 10,000 contacts, scaling to $100,000–$200,000+/year for larger deployments.

Who it’s for: Mid-market to enterprise consumer brands, media and publishing, fintech, and subscription businesses. Teams that want Braze-tier capabilities with a faster time-to-value and a slightly lower floor.

Who it’s not for: Anyone without a dedicated technical owner. Iterable works best when engineering and marketing share ownership of the platform. Like Braze, it’s not a tool you deploy in a sprint.

What about Omnisend, Drip, and Campaign Monitor?

Omnisend is worth mentioning as a legitimate Klaviyo alternative for ecommerce brands on Shopify, particularly at smaller list sizes (under 50,000 contacts) where Klaviyo’s per-profile pricing starts to bite. Omnisend typically runs 30–50% cheaper at equivalent contact counts. The integration catalog and partner ecosystem are thinner than Klaviyo’s, and the analytics are less deep, but for smaller DTC brands watching every line of their P&L, it’s a genuine option.

Drip is a DTC-focused automation platform positioned between Klaviyo and a general-purpose tool. Strong on lifecycle segmentation, weaker on integrations and partner ecosystem. Pricing starts at $39/month.

Campaign Monitor is design-first: excellent email templates, reasonable deliverability, very limited automation logic. It’s a newsletter tool masquerading as a marketing CRM. For anything beyond sends and basic sequences, it runs out of capability quickly.

The marketing CRMs we recommend against — and why

These are the tools you’ll encounter most often when searching. They’re widely used, many are free, and most of them will cap your marketing before you’ve really started.

Mailchimp

Mailchimp commands roughly 67% market share by customer count, which is mostly a measure of how effective a free tier is at accumulating accounts. The majority of Mailchimp’s 11 million users have never paid for the platform.

The honest assessment: Mailchimp is a newsletter tool. The automation is surface-level — a linear drip sequence with limited branching. The segmentation model is based on list membership and tags, not behavioural data. The contact record doesn’t connect meaningfully to a sales pipeline. The “audience” model forces you to manage contacts separately across different product lines or brands, which creates both operational friction and billing traps (you get charged for the same contact multiple times if they’re in multiple audiences).

Mailchimp has tried to add marketing CRM features over the years. The result is a product that is neither a capable email tool at scale nor a capable CRM — it sits in an uncomfortable middle.

The pricing becomes uncompetitive fast once you’re serious. At 100,000 contacts, Mailchimp costs approximately $800/month. Klaviyo at the same list size costs approximately $1,380/month but gives you real-time purchase data, automated revenue attribution per send, and ecommerce-native flows. For a DTC brand with a 100,000-person list, the economics of staying on Mailchimp stop making sense long before you hit that number.

Move on when: You need multi-step automation that branches on behaviour. You’re an ecommerce brand above 10,000 contacts. You want revenue attribution that isn’t an approximation.

Brevo (formerly Sendinblue)

Brevo is the most popular free alternative to Mailchimp and a genuine step up from it. The automation builder is more capable, the contact model is cleaner (contacts are not multiplied across audiences), and the pricing at small list sizes is very competitive — at 5,000 contacts, Brevo costs approximately $32/month versus Mailchimp’s $75/month.

At that price point and for that use case — a small business sending campaigns and basic automation — Brevo is a reasonable choice. The problems start when you try to grow with it.

The platform’s integration ecosystem is thin compared to HubSpot, ActiveCampaign, or Klaviyo. The lifecycle automation logic — particularly for B2B sequences that require CRM-level contact management, or ecommerce flows that require real-time purchase triggers — hits hard ceilings. Deliverability at scale has historically been inconsistent, partly because Brevo’s shared sending infrastructure includes a large proportion of very low-quality senders.

It’s also not built for the use cases where marketing CRMs earn their keep: attribution, lead scoring, sales-marketing handoff, revenue-attributed campaign reporting. These features exist on paper but are shallow in practice.

Move on when: You’re a B2B team that needs lead scoring and sales handoff. You’re an ecommerce brand where cart abandonment, browse behaviour, and post-purchase sequencing matter. You’re above 25,000 contacts and deliverability consistency becomes a business risk.

Constant Contact

Constant Contact is legacy infrastructure — a product built for sending newsletters in the early 2000s that has not fundamentally changed in its core model. It has 650,000 customers, most of them small businesses, nonprofits, and event-based organisations where email is a bulletin board, not a growth engine.

The automation is limited, the segmentation is basic, and the pricing is not competitive compared to Brevo or MailerLite at the same feature level. If someone is recommending Constant Contact in 2026, they haven’t evaluated the alternatives recently.

MailerLite and Kit (ConvertKit)

Both are fine for their intended audience and outside it for yours.

MailerLite is a clean, low-cost email tool for freelancers, small agencies, and businesses where email is a secondary channel. It’s well-designed, affordable, and does what it says. It is not a marketing CRM — there’s no meaningful contact management layer beyond list membership, no lead scoring, and no CRM sync that holds up in practice.

Kit (formerly ConvertKit) is designed specifically for independent creators — newsletters, course selling, digital product monetisation. It’s excellent at that use case. If you’re a content creator building a paid audience, Kit is probably the right tool. If you’re a B2B company, a SaaS business, or an ecommerce brand, it is the wrong category entirely. The product is not designed for your motion.

When to upgrade your marketing CRM

Most teams stay on their current platform about 18 months past the point at which it’s costing them revenue. Here’s how to tell where you are and when to move.

Mailchimp or Brevo → ActiveCampaign or HubSpot Starter

Trigger signals:

• You need an automation that branches — where one path goes to contacts who clicked and another to contacts who didn’t, and each path does something different

• You have a sales team that needs to see contact history before a call

• You’re spending more than two hours a week manually managing sequences or contact lists that a proper lifecycle tool would handle automatically

• Your “automation” is a linear drip sequence that doesn’t account for what contacts actually do

What you gain: Real automation logic, a connected CRM record that sales can use, proper lifecycle stages. What it costs: $50–200/month depending on list size. The revenue uplift from proper abandonment flows alone typically covers this within a month for an ecommerce brand above 5,000 contacts.

ActiveCampaign → HubSpot Professional

Trigger signals:

• Your sales team has grown to more than five reps and they’re managing deals in a spreadsheet or a disconnected CRM

• Marketing is generating leads but sales doesn’t know which ones are warm — you’ve lost the handoff

• You need multi-touch revenue attribution and your leadership is asking questions that require it

• You’ve hit the ceiling on ActiveCampaign’s contact management for complex B2B organisations with multiple stakeholders at the same account

What you gain: A true unified contact record across marketing and sales, pipeline management, meeting booking, sequences, and attribution in one system. What it costs: $800+/month at Professional. The one-time onboarding fee of $1,500 is required.

HubSpot → Marketo (B2B) or Braze/Iterable (B2C)

Trigger signals for B2B (Marketo):

• You’re running a complex enterprise sales cycle with multiple buyer roles and long nurture tracks that require sophisticated lead scoring models

• You have a large Salesforce instance and need deep bidirectional sync beyond what HubSpot’s Salesforce connector can reliably deliver

• Your marketing ops function is at least two dedicated headcount and you have the implementation budget ($100,000+ for a proper Marketo deployment)

Trigger signals for B2C/consumer (Braze or Iterable):

• Mobile engagement drives meaningful revenue and you need mobile push, in-app messaging, and email on a single orchestration layer

• You have more than 500,000 monthly active users and the per-event logic required to message them meaningfully at that volume is breaking your current tool

• A dedicated data engineering and marketing ops function exists and can own the platform

What you gain: Enterprise-grade compliance, revenue cycle modelling, infrastructure that doesn’t crack under scale. What it costs: $1,500–$6,000+/month for Marketo; $30,000–$100,000+/year for Braze or Iterable. Implementation costs are additional and significant — budget 2–3x the licence fee in year one.

The rule that applies at every stage

Don’t upgrade the platform until you’ve maximised what the current one can do. The most common mistake is buying a more powerful tool to solve a discipline problem. If you’re not using ActiveCampaign’s full automation capability, a HubSpot licence won’t fix that — you’ll just have the same unused potential at five times the price. Upgrade when you’ve hit the ceiling of the current tool, not when the current tool feels unfamiliar.

What marketing CRMs still can’t tell you

Here’s what most marketing CRM buyers don’t think about until six months in.

Your CRM captures the lead. It tracks what they opened, what they clicked, what form they filled in. What it doesn’t tell you is:

• Whether the content that brought them to your site is still ranking and driving awareness

• Whether a competitor just launched a campaign targeting your best-fit accounts

• Whether the message you’re sending resonates with how buyers in your category actually talk about the problem

• Whether the campaigns that generated your last 50 leads are actually responsible for the deals that closed

CRMs store contact history. They don’t model what’s happening in the market around you. That gap matters more as the market gets noisier and AI search changes how buyers find solutions.

This is where an intelligence layer above the CRM becomes the missing piece. Not a replacement for your CRM. A layer that connects your contact data to demand signals, brand positioning, and revenue outcomes — telling you not just who your leads are, but whether your market is moving toward you or away from you.

FAQ

Which CRM is best for marketing?

It depends on your business model. HubSpot is the default for B2B SaaS. Klaviyo is the standard for ecommerce. Customer.io is strongest for subscription apps and product-led growth. See the full breakdown by use case above.

What is the best free marketing CRM?

HubSpot Free gives you a functional CRM with basic email marketing. It’s limited on automation but works as a starting point for small teams. ActiveCampaign has a free trial. Zoho CRM has a free tier with core contact management features.

What’s the difference between a CRM and marketing automation?

A CRM stores contact records and interaction history. Marketing automation is the engine that sends messages, scores leads, and triggers workflows. The best marketing CRMs bundle both. When they’re on separate platforms, you need a reliable sync between the two or you’ll be working with incomplete data.

Is AI going to replace CRM?

No. AI will make CRMs significantly more useful — better segmentation, faster content generation, smarter lead prioritisation — but you still need a structured record of every contact, conversation, and campaign interaction. What AI does change is the intelligence layer above the CRM: the ability to connect contact data to what’s happening in your market, not just what’s in a single platform.

What is the best CRM for a marketing agency?

GoHighLevel is purpose-built for agencies managing multiple client accounts with white-label capability and sub-account structure. HubSpot is a strong option if your clients are mid-market B2B companies who may already be on HubSpot and want unified reporting.
