What the invoice doesn't show
Mailchimp
Mailchimp counts ALL contacts toward your billing tier — subscribed, unsubscribed, and non-opted-in. Unsubscribed contacts remain billable unless you manually archive them. A company with 10,000 'contacts' might have 3,000 active subscribers but pays the 10,000-tier rate.
Mailchimp deprecated the Classic Automation Builder in June 2025, pushing multi-step automations exclusively into the Standard plan ($20/mo minimum). Organizations running basic welcome sequences on Free or Essentials were forced to upgrade overnight.
When you exceed your contact or send limit, Mailchimp automatically adds extra email blocks and charges your next invoice — without an upgrade prompt or warning. The exact overage pricing isn't publicly listed, making costs impossible to predict.
Since Intuit acquired Mailchimp for $12B in 2021, pricing has increased 20-30% across paid tiers (Essentials from $9 to $13, Standard from $14 to $20), the free plan was gutted from 2,000 contacts to 250 — an 87.5% reduction — and an additional 11-13% increase was implemented in April 2026, pushing Premium's base to $375+/mo.
Marketo
Marketo charges on total database records — not just contacts you actively market to. Unsubscribed, bounced, and inactive contacts all count toward your pricing tier. Growing companies get punished: small increases in records push into higher tiers.
Professional implementation costs $15,000-$50,000+ through certified partners, taking 60-90 days. A dedicated Marketo Administrator costs $85,145/year (median US salary). A Marketo Consultant averages $104,000/year. Teams without dedicated admin consistently underutilize the platform.
Growth-tier plans cap at 50,000 API calls/day. Salesforce sync maxes at 100,000 records/day. Teams running heavy CRM syncs or enrichment tools regularly hit limits. In 2023, Adobe added 'Scoping Parameters' introducing new cost drivers around activities, API calls, and sync limits.
Advanced attribution (Marketo Measure), predictive scoring, ABM modules, and SMS credits all require separate contracts on top of base subscription. The average Marketo contract across 117 real deals is $112,544/year — far above the $1,295/mo entry price (Adobe raised the base package from $895/mo to $1,295/mo in 2025, a 44% increase).
