HubSpot vs Kit pricing

Kit prices active unique subscribers and never meters sends on paid plans. HubSpot prices an edition base, then Core Seats, then marketing-contact packs on top. Comparing a HubSpot Starter seat sticker to a Kit Creator cell without saying which seats and which contact packs are in play mixes two meters.

HubSpot cells on this page prefer the Product and Services Catalog. The Marketing pricing UI can show suite or Customer Platform packaging, but its Marketing Hub list prices match the catalog, as do those on HubSpot's pricing calculator, read 26 September 2026. Only promotional prices, such as the new customer Starter seat, stay out.

ConvertKit rebranded to Kit. SideBySend records one Kit dataset. The ConvertKit pricing URL stays as an alias so the old name still lands on the same numbers.

Kit paid plans include unlimited email sends, so volume never moves the bill. HubSpot marketing email send limits scale with the marketing-contact tier: Starter at 5 times, Professional at 10 times, and Enterprise at 20 times that tier. Those HubSpot multiples are catalog feature limits, not a separate dollar meter.

Kit. Kit bills confirmed subscribers only, and its help pages list every other status as outside the billing total: unsubscribed, complained, bounced, blocked and unconfirmed. Hard bounces are unsubscribed automatically.

HubSpot. For new customers after 5 March 2024, Marketing Hub Starter is priced per Core Seat, and Professional and Enterprise start at a base price that includes Core Seats. Marketing contacts sit on top of the edition: included contacts come with the base, and further contacts are sold in catalog bands. Non-marketing contacts are free up to an overall contact ceiling of 15 million (marketing plus non-marketing). Exceeding the marketing-contact tier bills immediately. Designating contacts as non-marketing takes effect at the start of the following month or contract renewal, whichever comes first, and contact-tier downgrades wait until renewal.

No visual automations or email sequences. Sends, forms and landing pages are unlimited, so what usually forces a Kit user onto a paid plan is the first automation or sequence rather than the subscriber ceiling. HubSpot Marketing Hub has no free edition on the recorded catalog ladder.
