Best Comprehensive Marketing Automation Platforms

Website: https://www.hubspot.com

Best for: Teams that want a CRM and marketing automation in one system

Starting price: $20 per seat/month

Free plan: Yes

Pros: Built-in CRM with a marketing-contacts model, with non-marketing contacts stored free up to 15 million overall; full automation stack on higher tiers, with A/B testing, lead scoring and multi-touch attribution

Cons: Mandatory onboarding of $3,000 on Pro and $7,000 on Enterprise; automation is capped at 1 action on the free tier and 10 actions on Starter, and A/B testing needs a higher tier

HubSpot Marketing Hub Starter costs $20 per seat a month, with Professional at $800 a month billed annually and Enterprise at $3,600. The free tier includes 2,000 email sends a month, HubSpot branding, forms, live chat and basic email. The platform is built around its CRM and a marketing-contacts model: non-marketing contacts can be stored free up to 15 million overall, and Starter includes 1,000 marketing contacts, Professional 2,000 and Enterprise 10,000. Higher tiers add unlimited email automation actions, A/B testing, lead scoring and multi-touch attribution on Enterprise.

The limits are the onboarding fees and the automation caps. Professional and Enterprise carry mandatory onboarding fees of $3,000 and $7,000, and real automation is gated upward: the free tier allows 1 automated action, Starter allows up to 10 actions per workflow, and A/B testing and multi-touch attribution need Professional or Enterprise. The email send limit is 5 times the marketing contact tier a month on Starter, 10 times on Professional and 20 times on Enterprise.

Best for: Large B2B teams that need deep journey automation

Starting price: quote only

Free plan: No

Pros: Native CRM integrations with Salesforce, Microsoft Dynamics and Veeva, plus segmentation, lead scoring and journey automation across email, social and landing pages; enterprise depth on higher packages, with ABM, predictive audiences and Marketo Measure attribution

Cons: Quote-only pricing with no self-serve trial and no public entry price; Growth is capped at 10 users and 20,000 API calls a day

Marketo Engage, now part of Adobe, sells four packages, Growth, Select, Prime and Ultimate, and every package shows a Get pricing button, so the platform is quote only. There is no free plan and no free trial: entry is through a sales conversation and demo only. Its strengths are native CRM integrations with Salesforce, Microsoft Dynamics and Veeva, plus segmentation, lead scoring and routing, and journey automation across email, social, landing pages and media. Higher packages add target account management, predictive audiences and Marketo Measure attribution on Ultimate.

Adobe publishes no prices, and third-party estimates of around $900 or more a month for Growth are unverified and should not be used for budgeting. Growth is capped at 10 users and 20,000 API calls a day, while the other tiers allow 25 users and 50,000 calls a day, so larger programs must buy up. Packages are sold as yearly or multi-year licences, and ABM, predictive content and Marketo Measure are gated to Prime or Ultimate.

Best for: Salesforce CRM users who need B2B marketing automation

Starting price: $1,250 per org/month (billed annually)

Free plan: No

Pros: Native to Salesforce CRM, with lead nurturing and scoring, B2B Marketing Analytics and Agentforce Campaign Creation; Account Engagement+ editions include Marketing Cloud Next, with multi-channel journeys, forms and landing pages

Cons: It only runs with Salesforce CRM, with Enterprise or Unlimited Edition required; the entry price is $1,250 an organisation a month on an annual contract, and Marketing Cloud Next features need separately purchased credits

Salesforce Marketing Cloud Account Engagement, formerly Pardot, starts at $1,250 an organisation a month billed annually for Growth+, with Plus+ at $2,750, Advanced+ at $4,400 and Premium+ at $15,000. Marketing Cloud Next Growth Edition is $1,500 and Advanced Edition $3,250 an organisation a month, billed annually. There is no free Marketing Cloud edition.

Account Engagement+ editions include Marketing Cloud Next, adding multi-channel journeys, forms and landing pages, and two-way SMS and WhatsApp on Advanced. The limits are the CRM requirement and the credit costs: it only runs with Salesforce CRM, with Enterprise or Unlimited Edition required for every edition, and using Marketing Cloud Next features costs extra Einstein Request Credits, Messaging Credits and Data 360 Credits on top of the edition price. The Premier Success Plan costs 30 percent of net licence fees. Growth+, Plus+ and Advanced+ include 10,000 contacts, Premium+ 75,000, and additional contacts cost $100 per 10,000 a month.

Free plan: Free trial (14 days)

Pros: Multi-step automation builder with AI-powered automation and campaign builders, 250+ email templates and unlimited automation actions from Plus; predictive sending, conditional content and attribution on Pro

Cons: No free plan, and Starter is deliberately limited, with each automation capped at 5 actions and 1 user; SMS, WhatsApp and CRM pipelines are extra-cost add-ons, and Salesforce integration is Enterprise only

ActiveCampaign Starter costs $15 a month billed annually for 1,000 contacts, with Plus at $49, Pro at $79 and Enterprise at $145, and monthly billing is about 20 percent higher. There is no free plan, but the 14-day trial needs no credit card. The multi-step automation builder comes with AI-powered builders, 250 or more email templates, forms, landing pages and site messages, with unlimited automation actions from the Plus plan. Pro adds predictive sending, conditional content, advanced segmentation and attribution.

The limits are the Starter caps. Starter is deliberately limited: each automation is capped at 5 actions and the plan includes 1 user. SMS, WhatsApp, transactional email and CRM pipelines are extra-cost add-ons, and Salesforce integration is Enterprise only. Prices rise with contact count on every plan. Monthly email sends are capped at 10 times the contact limit on Starter and Plus, 12 times on Pro and 15 times on Enterprise.

Website: https://mailchimp.com

Best for: Small teams that want a free plan and simple flows

Starting price: $13 per month

Free plan: Yes

Pros: Up to 200 marketing automation flows and predictive segmentation on Standard, with generative AI features and dynamic content; 300+ integrations, popup forms, landing pages and A/B testing, with phone support on Premium

Cons: The free plan has no automation flows and no email scheduling; Essentials caps flows at 4 steps, and SMS and transactional email are extra-cost add-ons

Mailchimp Essentials costs $13 a month for 500 contacts, Standard $20 and Premium $350 a month, with no standard annual prepay discount. The free plan covers up to 250 contacts and 500 sends a month, with 1 seat, 1 audience and email support for the first 30 days only. A 14-day trial is available for Standard or Essentials. Standard allows up to 200 marketing automation flows and predictive segmentation, with generative AI features and dynamic content, and Premium adds a dedicated onboarding specialist.

The free plan has no automation flows and no email scheduling, so a buyer who wants automation must move to a monthly plan, and automation is thin on Essentials, which caps flows at 4 steps. SMS marketing and transactional email are extra-cost add-ons, and Mailchimp bills on total contacts stored, including unsubscribed contacts, unless they are archived. The monthly send allowance is 10 times contacts on Essentials, 12 times on Standard and 15 times on Premium.

Website: https://www.brevo.com

Best for: Teams that email a large list infrequently

Starting price: $9 per month

Free plan: Yes

Pros: Send-based pricing instead of contact-based pricing, so a large list emailed infrequently costs less; multi-channel in one account, with email, SMS, WhatsApp, web push and popups, and unlimited workflows from Standard

Cons: Removing the Brevo logo costs an extra $10.80 a month on Starter; low tiers cap stored contacts at 500, and the jump from Standard at $18 to Professional at $499 has no tier in between

Brevo Starter costs $9 a month for 5,000 emails a month, or $8.08 a month billed yearly, with Standard at $18, Professional at $499 a month from 150,000 emails a month, and Enterprise from $2,499 a month. Yearly billing saves 10 percent. The free plan is free forever at 300 emails a day, with storage for up to 100,000 contacts. Brevo bills on emails sent instead of contacts stored, so a large list emailed infrequently costs less. Starter includes a drag-and-drop editor, AI content generator, advanced segmentation, forms and transactional email, and the platform covers email, SMS, WhatsApp, web push and popups, with unlimited workflows and A/B testing from Standard.

The limits are the contact caps and the tier jump. Removing the Brevo logo costs an extra $10.80 a month on Starter, low tiers cap stored contacts at 500, and the jump from Standard at $18 to Professional at $499 a month has no tier in between. Phone support and WhatsApp are Professional only. Starter covers up to 100,000 emails a month and Standard up to 500,000.

Website: https://www.klaviyo.com

Best for: Ecommerce brands that want behaviour-triggered flows

Starting price: $20 per month

Free plan: Yes

Pros: Segmentation, campaigns and flows with A/B testing on monthly plans, plus 350+ integrations and deep ecommerce data for behaviour-triggered messaging; the Marketing plan bundles Social marketing, Reviews and Customer Hub

Cons: Billing is on all active profiles, so the price climbs steeply, reaching $150 a month at 10,000 profiles; SMS and MMS are an extra-cost add-on, and free-plan email support lasts only 60 days

Klaviyo Email costs $20 a month for 500 active profiles and 5,000 emails a month, Marketing $25 a month at 500 profiles, with the first month at $1 for eligible new accounts, and Custom over 150,000 profiles. Prices are monthly, with no annual discount. The free plan covers up to 250 active profiles and 500 emails a month, and it already includes Customer Hub, Customer Agent with 10 resolutions a month and Helpdesk with 10 tickets a month. Segmentation, campaigns and flows with A/B testing sit on the monthly plans, with 350 or more integrations, and the Marketing plan bundles Social marketing, Reviews and Customer Hub.

The catch is the profile counting: billing is on all active profiles, not only contacts emailed, so the price climbs steeply, reaching $150 a month at 10,000 profiles and $720 at 50,000. SMS and MMS are an extra-cost add-on on every plan, email support on the free plan lasts only the first 60 days, and SSO, a dedicated CSM and SLAs are Custom-plan only. The email send allowance is 10 times the active profile count a month.
