What the invoice doesn't show
ActiveCampaign
Contact-tier pricing creates steep jumps: 1K to 5K contacts on Plus leaps from $59/mo to $179/mo — a 203% increase. As of November 2025, new accounts are charged for ALL contacts including unsubscribed, bounced, and unconfirmed — people you legally cannot email.
Users report bills doubling without changing plans. Specific complaints: '$588 to $1,800 after five years,' '$1,400/month suddenly turned into $2,800/month for the exact same list and features.' G2 shows 403 mentions of 'Expensive' as a complaint category.
Core features sold separately: SMS ($21/mo activation + per-message credits), CRM Pipelines ($49-107 first user), Custom Reports ($159/mo), Dedicated IP ($750 one-time). Real yearly cost is 20-40% higher than advertised.
AI and advanced features locked to higher tiers: predictive sending and content optimization are Pro-only ($235/mo at 5K contacts). The Starter plan caps at 25K contacts — forced upgrade to continue growing.
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.
