Flagship · private pilot
Email that runs itself, for Shopify brands and for AI agents.
Three lanes, one platform.
Agent-run Shopify marketing
Segments, campaigns and automated flows: welcome, abandoned cart and post-purchase.
Developer API
Transactional email such as receipts, notifications and password resets.
Inboxes for AI agents
Addresses that agents can send from and receive in.
Where it goes further
Five things most email tools leave to you.
01 · Plain-English segments
“bought twice, not in 60 days”
Type it and get a validated segment with a live count.
02 · On-brand by default
The store's logo, colours and fonts become a brand kit that every email uses.
03 · Predictions from day one
Expected next order, churn risk and lifetime value per customer, with no minimum history required.
04 · Proven lift, not borrowed credit
Automatic holdout groups measure the revenue each campaign actually adds.
05 · Deliverability built in
- Sunsetting unengaged contacts
- Per-contact send-time optimisation
- Frequency caps

Humans approve, agents do the work
