About the marketing automation category
B2B marketing automation in 2026 has three distinct tiers. 'SMB accessible' (HubSpot Marketing Hub Starter $15/seat/month to Professional $800/month, Customer.io Essentials $100/month): self-serve, published pricing, 5-to-100-person marketing teams. 'Enterprise B2B' (Marketo Engage $1,200-8,000+/month, Salesforce Pardot/Account Engagement $1,250-15,000/month): custom pricing with 6-12 month implementations, 100+ person marketing orgs with dedicated operations teams. 'Product-led engagement' (Braze $50k-500k+/year, Customer.io Premium $1,000/month+): mobile-first consumer brands (gaming, retail, fintech) running push notifications + SMS + in-app + email orchestration based on product events. Distinct from email-marketing (Mailchimp, ConvertKit, ActiveCampaign — covered separately) which focuses on newsletter + drip sequences. Marketing automation emphasizes lead scoring + attribution + CRM integration + account-based marketing (ABM) for B2B sales funnels. HubSpot dominates SMB/mid-market B2B (growing fastest). Marketo remains enterprise incumbent. Pardot (Salesforce) is the default when you already use Salesforce Sales Cloud. Braze dominates consumer mobile engagement. Customer.io is the developer-friendly middle ground.
How to choose between marketing automation options
First: B2B or B2C? B2B lead generation with sales hand-off: HubSpot Marketing Hub (SMB/mid-market) or Marketo/Pardot (enterprise). B2C product engagement (mobile app, SaaS onboarding, e-commerce): Braze or Customer.io. Second: what's your team size and sophistication? Marketing team 1-5 people: HubSpot Marketing Hub Starter at $15/seat/month or Customer.io Essentials at $100/month. Marketing team 5-20: HubSpot Professional at $800/month or Customer.io Premium. Marketing ops team 20+ with dedicated automation architects: Marketo Engage or Pardot. Third: CRM integration depth? Salesforce Sales Cloud primary: Pardot is natively built on Salesforce Lightning, one codebase. HubSpot Sales Hub primary: Marketing Hub natively integrates. Other CRMs (Dynamics, Pipedrive): HubSpot via integrations or Marketo standalone. Fourth: budget range? Under $500/month: HubSpot Starter + Customer.io only. $500-2,000/month: HubSpot Professional or Pardot Growth. $2,000-10,000/month: Marketo Select/Prime or Pardot Plus/Advanced. $10,000+/month: Marketo Ultimate, Pardot Premium, Braze, or HubSpot Enterprise. Fifth: contacts database size? HubSpot charges by 'marketing contacts' (contacts you actively market to, not total CRM contacts) — this is the key pricing lever. Marketo/Pardot use total contacts. Braze uses monthly active users (MAU). Customer.io uses 'profiles' (users + objects). Sixth: regulatory compliance (HIPAA, HITRUST, FedRAMP)? Customer.io Premium has HIPAA; HubSpot Enterprise has HIPAA; Marketo and Pardot Enterprise tiers have HIPAA with BAAs.
