[ 03 / 05 ]Tiers

What's the difference between Free, Starter, Pro, and Scale?

Tiers add companies and features. Volume is picked separately.

Free

One company and a one-time starting allowance. Everything you need to build and test.

Starter

Up to 3 companies, for a founder running a handful of products.

Pro

Up to 20 companies, plus A/B testing, translations, and the optimisation plan.

Scale

Up to 100 companies and the highest sending volumes.

Enterprise

Custom volumes and terms, set up with us directly.

[ 04 / 05 ]Credits

What do AI credits pay for?

Work with a real cost behind it. Your volume covers the email you send, address checks before a first send, and turns with the in-app copilot.

  • MCP tool calls use no credits. Your agent runs on your own Claude or ChatGPT plan.
  • Copilot turns are metered on the tokens actually used, not a flat charge.
  • Top-up credits never expire.
  • Upgrades apply straight away. Downgrades wait until your next renewal.

Key takeaway

If it costs us nothing to run, it costs you nothing to use.
