Sitebase vs Kit (ConvertKit)

Do you need a dedicated email marketing tool?

Kit is creator email marketing — forms, broadcasts, automations — from $29/mo at 1k subscribers. Sitebase includes newsletter signup + broadcasts as one feature of a toolkit that runs your whole website — forms, subscribers, analytics, testimonials, uptime — for $39/mo total.

Join the waiting list

Kit (ConvertKit) alone starts at $29/mo. Sitebase replaces it and the rest of the stack.

With Sitebase

Newsletter signup + broadcasts

  • Signup forms (inline or exit-intent popup) with double opt-in, embedded anywhere with one snippet
  • Send broadcasts from the dashboard with your own Resend key — you pay Resend's cents, not per-subscriber pricing
  • Subscribers, analytics, and the rest of your site's features in one place
Where Kit (ConvertKit) wins

The honest part

  • Kit's automations, sequences, tagging, and deliverability tooling are far deeper
  • Serious newsletter businesses should use a dedicated ESP; Sitebase covers capture + occasional sends

If that's what you need, use Kit (ConvertKit) — it's a good tool. Sitebase is for when you'd rather run one subscription than ten.
