How to choose a marketing automation platform for your team

Updated: October 2026. Rewritten as a buyer's guide with the same fields for every vendor, pricing checked on vendor sites in October 2026, and three older posts on automation tools merged in.

The marketing automation platform you need is decided by two things before features: which CRM holds your revenue data, and whether you sell to businesses through a sales team or to consumers through a store. Get those right and the shortlist is two or three vendors; get them wrong and no feature list will save the implementation.

This guide is for marketing leaders and martech leads choosing or replacing a platform for email, lifecycle and lead nurturing. It is not for teams that only need a newsletter tool, and it does not cover customer engagement platforms built for mobile apps.

How I compared them. The criteria: CRM fit, the channels and journeys each platform handles, data model and integrations, pricing model and total cost, and the operational effort to run it. Pricing comes from each vendor's public pricing page, checked in October 2026; capabilities come from the vendors' own product pages and from the earlier versions of this post. I have not run a side-by-side test of these eight platforms, and I did not verify deliverability, support quality or AI features.

You need a platform when manual sends stop scaling

A marketing automation platform earns its cost when at least one of these is true:

• Lead nurturing depends on behavior. You want what someone did (pages viewed, forms submitted, emails opened) to decide what they receive next, without someone building each send.
• Sales needs a handoff. Marketing has to score leads and pass them to sales with context, and you need to know what happened to them afterwards.
• E-commerce lifecycle is manual. Abandoned cart, post-purchase, replenishment and win-back flows are sent by hand or not at all.
• Channels are disconnected. Email, SMS and, in retail, store and online interactions are run from separate tools with separate lists.

If you send a newsletter and a few campaigns a month to one list, an email tool is enough. Buying a platform for workflows nobody will build is the most common way these projects fail.

The criteria that decide the choice

Not every criterion weighs the same. Here is how I would weight them by case.

CRM fit: the criterion that decides most B2B choices

Marketing automation without a clean sync to the CRM produces leads nobody follows up and revenue nobody can attribute.

• What to check: whether the integration is native or goes through a connector, which objects sync (leads, contacts, accounts, opportunities, custom objects), in which direction, and how often.
• Why it matters: closed-loop reporting, from campaign to closed-won deal, depends on it. So does lead scoring that sales trusts.
• How to verify: ask for a demo on a sandbox connected to your own CRM, not a vendor demo account.

Channels and journeys

• What to check: email, SMS, push, in-app, ads audiences, landing pages and forms; whether one journey can branch across channels.
• Weight: high for e-commerce and retail, where cart, browse and post-purchase flows are the core use. Medium for B2B, where email and the sales handoff dominate.

Data model and integrations

• What to check: whether the platform stores events (what people did) or only contact fields; whether it can receive events from your site, app and e-commerce platform; whether it can send data back to the warehouse.
• Why it matters: segmentation and personalization are only as good as the behavioral data the platform can see. A platform that cannot export its data locks your engagement history in.
• Measurement: check how UTM parameters and campaign IDs are carried into your analytics, so automated emails are attributed correctly. Poor integration creates silos that undo the reason you bought the tool.

Pricing model and total cost

• What to check: whether the price scales with contacts, emails sent, seats, or a fixed org fee; onboarding fees; overage charges; add-ons for SMS or extra features.
• Why it matters: a platform that is cheap at a few thousand contacts can become the largest line in the martech budget at a few hundred thousand. Model your contact growth over three years before signing.

Effort to run it

• What to check: who will build and maintain workflows, scoring models and templates; whether that needs a dedicated marketing operations person.
• Why it matters: enterprise platforms are more flexible and need more expertise. The most powerful platform delivers nothing if the team cannot use it. Ask for a trial and have the people who will use it build one real workflow.

Privacy and consent

• What to check: how consent and unsubscribe status are stored and synced, regional data residency, and support for your consent management setup.
• Weight: high in the EU and for any team sending SMS.

Questions for the RFP

Copy, adapt and send:

1. Which CRMs do you integrate with natively? Which objects sync, in which direction, and at what frequency?
2. How is the price calculated: contacts, sends, seats or org? What does it cost at our contact count today and at three times that?
3. What one-time fees apply: onboarding, implementation, data migration, dedicated IP?
4. Which behavioral events can we send to the platform, and through what (SDK, API, e-commerce integration, CDP)?
5. Can we export all contact, event and engagement data, in bulk, to our warehouse? On which plan?
6. How are consent and unsubscribe status stored, and how do they sync with our CRM and consent tool?
7. Where is data stored, and can we choose the region?
8. Which features in the demo are add-ons or require a higher tier?
9. How do you migrate existing workflows, templates and engagement history from our current platform?
10. Can we have a sandbox connected to our own CRM during the evaluation?

Red flags

• No sandbox with your own data. If the vendor can only show its demo account, you cannot judge CRM fit.
• "All integrations are native." Ask for the documentation of the one you need. A connector maintained by a third party is a different risk.
• No bulk export. Your engagement history should not be hostage to the renewal.
• Pricing that only appears after three calls, with no answer to "what does it cost at three times our contacts?"
• AI claims without a way to measure them. Ask how you would test the feature against a holdout.

The vendors, by the job they do

Email and simple automation for small teams

Brevo

• What it does: email, SMS and a basic sales CRM in one product. Formerly Sendinblue; the company renamed itself Brevo in 2023.
• Best for: small teams that want email, SMS and simple automation at a low entry cost.
• Not for: complex multi-branch journeys or B2B lead scoring with a large sales team.
• Pricing (public, October 2026): not verified; the pricing page did not render when I checked.

Mailchimp

• What it does: email marketing with templates, audience segmentation and pre-built automations.
• Best for: beginners and small businesses focused on email.
• Not for: advanced automation, lead scoring or a sales handoff.
• Pricing (public, October 2026): free plan up to 250 contacts; paid plans scale with contacts and are shown in local currency.

E-commerce and retail lifecycle

Klaviyo

• What it does: email and SMS built around e-commerce events and customer profiles, with integrations to platforms such as Shopify.
• Best for: online stores whose main automation is cart, browse, post-purchase and win-back flows.
• Not for: B2B lead nurturing with a sales team. Cost scales with the size of your profile list.
• Pricing (public, October 2026): free plan up to 250 profiles and 500 emails a month; paid tiers were not shown on the page I checked.

Omnisend

• What it does: email, SMS and push for e-commerce, with pre-built automation for stores.

For retailers with physical stores, the question is less which email tool and more whether store transactions and loyalty data reach the platform at all. If they do not, the "omnichannel" journey only covers online buyers.

CRM and automation in one platform for growing teams

ActiveCampaign

• What it does: email marketing, a visual automation builder and a built-in CRM.
• Best for: small and mid-sized businesses that need more advanced automation than an email tool without enterprise pricing.
• Not for: teams that want it to run with no onboarding; the automations take time to learn.
• Pricing (public, October 2026): priced per 1,000 contacts and billed yearly; the amounts did not render on the page when I checked, so not verified.
• Source: ActiveCampaign pricing

HubSpot Marketing Hub

• What it does: marketing automation on top of HubSpot's own CRM, with email, landing pages, forms, social and ads in one platform.
• Best for: mid-sized B2B and B2C companies that value usability and want CRM and automation from one vendor.
• Not for: teams committed to another CRM, or with very large contact lists on a tight budget. The cost grows with tiers and contacts.
• Pricing (public, October 2026): free plan for up to 2 users; Starter priced per seat; Professional from $800/month with 3 core seats and 2,000 marketing contacts, plus a $3,000 one-time onboarding; Enterprise from $3,600/month with 5 core seats and 10,000 marketing contacts, plus a $7,000 onboarding.

Enterprise B2B automation

Adobe Marketo Engage

• What it does: B2B marketing automation for complex lead management, scoring, account-based programs and large-scale campaign orchestration. Part of Adobe since its 2018 acquisition of Marketo.
• Best for: large B2B organizations with a dedicated marketing operations team, especially if they use Adobe Experience Cloud.
• Not for: small teams without marketing operations capacity. The learning curve is steep.
• Pricing (public, October 2026): not public; quoted by sales.
• Source: Adobe Marketo Engage

Salesforce Marketing Cloud Account Engagement

• What it does: Salesforce's B2B marketing automation, formerly Pardot (renamed in 2022), with lead scoring and grading, nurturing and reporting tied to Salesforce opportunities.
• Best for: B2B teams whose sales organization already runs on Salesforce.
• Not for: companies not on Salesforce CRM, or B2C lifecycle marketing at volume.
• Pricing (public, October 2026): Growth from $1,250 per org per month, billed annually; Plus $2,750; Advanced $4,400; Premium $15,000. Annual contract required.

Summary with the same criteria

My recommendation by case

The segmentation from the earlier version of this guide still holds as a starting shortlist:

• A solo marketer or a startup: start with Mailchimp or Brevo, and move only when you need behavioral journeys.
• A growing small or mid-sized business: ActiveCampaign, or Omnisend if you are e-commerce.
• An e-commerce or retail brand: Klaviyo or Omnisend. Check how store and loyalty data will get in.
• A mid-sized B2B company: HubSpot Marketing Hub if you can also use its CRM; ActiveCampaign if budget is the constraint.
• A large B2B enterprise on Salesforce: Account Engagement, or Adobe Marketo Engage if you need more complex programs and have the operations team to run it.

Whichever you choose, the tool should follow the strategy, not define it. Map the journeys first, then check how the platform fits the rest of your martech stack, and plan the integration with your CRM and analytics before you sign. When the platform is live, judge it on what it adds to revenue against a holdout, not on open rates; the method is in how to improve marketing ROI.

Switching platforms has its own risks: historical engagement data that does not migrate, workflows rebuilt in a hurry, and a team that has not been trained. Budget time for all three.

What to check this week

• Write down your CRM and your main use case (B2B handoff or e-commerce lifecycle). That alone halves the shortlist.
• Model the price at three times your current contacts for your two finalists, including onboarding fees.
• Ask both finalists for a sandbox connected to your own CRM, and have the person who will run the platform build one real workflow in each.
