What the invoice doesn't show
HubSpot Marketing
Professional requires a $3,000 mandatory non-refundable onboarding fee charged at signing — Enterprise requires $7,000 — regardless of whether your team uses the service.
Marketing contacts auto-escalate but never auto-downgrade: crossing 2,001 contacts on Professional immediately triggers the 5,000-contact tier, adding ~$250/month — even temporarily importing 50 contacts past a threshold locks in the higher rate.
Professional and Enterprise plans are annual contracts with no mid-term exits. Miss the cancellation window and HubSpot auto-renews for another 12-month term at your current rate.
Core capabilities are metered add-ons on top of the $890/mo base: a dedicated sending IP runs ~$300/mo, the reporting add-on ~$200/mo, API limit increases ~$500/mo, and Breeze AI credits ~$30/mo per 1,000 credits.
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.
What teams are switching to
Replacing HubSpot Marketing
ActiveCampaign
Starter $15/mo, Plus $49/mo, Pro $79/mo at 1,000 contacts (annual billing); scales by contact count
Delivers comparable marketing automation depth — 950+ automation templates, predictive sending, behavioral triggers, and lead scoring — at a fraction of HubSpot Professional's price. No mandatory onboarding fee and no annual lock-in trap; contact-count pricing scales linearly without punishing tier jumps.
Brevo
Starter from $9/mo; Business from $49/mo — priced per emails sent, not per marketing contact stored
Prices by email volume rather than contact count, which eliminates the core escalation mechanic that makes HubSpot expensive at scale. Full branching automation, A/B testing, SMS, and landing pages are available from the Business tier with no forced onboarding fees or annual lock-in.
EngageBay
Free plan; Basic $11.95/user/mo; Growth $45.99/user/mo; Pro $79.99/user/mo (annual billing)
An all-in-one platform (CRM, marketing automation, and helpdesk in a single subscription) that removes the add-on stacking that inflates HubSpot TCO. Includes unlimited contacts on Pro, advanced A/B testing, and custom reporting at a per-user price well below HubSpot's per-seat add-on rate, with no mandatory onboarding fee.
Replacing Mailchimp
Brevo
Free (300 emails/day), Starter $9/mo, Business $18/mo
Charges by emails sent, not contacts stored. Unlimited contacts on all plans including free. Includes transactional email, SMS, and WhatsApp in one platform. A 50,000-contact list sending 50K emails/mo costs ~$35/mo vs Mailchimp's $450+.
Kit (formerly ConvertKit)
Free (10K subscribers), Creator $39/mo
Creator-focused with visual automation builder on all paid plans. Free plan supports up to 10,000 subscribers — 40x Mailchimp's free tier. No charge for unsubscribed contacts.
Loops
Free (1K contacts), $49/mo (5K contacts, unlimited sends)
Built for SaaS companies. One flat tier with all features — no feature gating at all. Includes marketing, transactional, and product emails in one platform. Unlimited sends on all paid plans.
