HubSpot Marketing Hub Professional
- About $890 a month with 3 seats and 2,000 marketing contacts, plus a one-time onboarding fee of about $3,000. Above 2,000 contacts HubSpot charges more in contact tiers; we don't have a public figure for every tier, so the calculator shows "more than" the 2,000-contact price.
- HubSpot's list price has moved between $800 and $890 in 2026 (third-party price tracking, pricingsaas.com). Check hubspot.com/pricing for today's price.
- HubSpot does not allow downgrades during a term (HubSpot Customer Terms, updated 2026-09-16).
Salesforce Marketing Cloud Engagement
List prices per org per month, billed yearly (salesforce.com, Engagement pricing, read 2026-10-12):
| Edition | Per month | Includes |
|---|---|---|
| Pro+ | $2,000 | 2.5M emails, 15,000 contacts, Marketing Cloud Growth |
| Corporate+ | $5,500 | 10M emails, 1M mobile messages, 45,000 contacts, Marketing Cloud Advanced |
| Enterprise+ | $30,000 | 150M emails, 10M mobile messages, 500,000 contacts, Marketing Cloud Advanced |
- The calculator picks the smallest edition whose contacts fit. Check the email allowance against your contract.
- Add-ons cost extra: Intelligence+ from $11,000 a month and Personalization+ from $15,000 per org a month (Salesforce blog, 2025).
- Subscriptions renew automatically for a year unless notice is given 30 days before the term ends, and a renewal at lower volume is re-priced without the old per-unit price (Salesforce MSA §11.2, updated 2026-09-01).
