Pricing
ESP-class depth on Spark. A few upgrades when you need them.
Mail Genie is not a crippled free ESP. Compose, templates, brand themes, sequences, and honest send totals ship on free Spark. Higher tiers cut the cost of every thousand emails — and unlock domains, API keys, and webhooks when you need them.
Spark · free to start
Start with almost everything
No subscription wall for the core job. Create a GenieOS Spark account, compose brand-aware emails, and expand into the rest of the OS when you are ready.
- Genie compose chat (credit-metered)
- MJML templates + visual block editor
- Brand kit → email themes
- Sequences basics + list enrolment
- Test send from the designer
- Send totals + open/click rollups
- 50 credits / 1,000 emails (hosted)
- Lists & contacts
Send economics
Fewer credits per 1,000 emails as you climb
Spark starts at 50 credits / 1,000. Glow halves that to 25. Ignite and Star sit at 20 — and bring-your-own ESP sends drop as low as 0.4 credits / 1,000 on Star. Same numbers as GenieOS pricing.

Same rates as genieos.pro/pricing. One credit is the meter — higher tiers buy a better rate, not access to email itself. BYO = send through your connected ESP.
