We build the full pipeline: capture, double opt-in, segmentation, sending, and the deliverability plumbing (SPF/DKIM/DMARC) that keeps you out of spam. Self-hosted, no per-subscriber tax. The signup below is a demo — it sends nothing.

In a real build: a double opt-in email goes out, the subscriber is tagged/segmented on confirm, and they're added to the right sending stream — all on your own infrastructure.
Lead story. A clean, on-brand template that renders in every client — not just the one you tested.
Segmented. Power users, trial users, and churned users each get a version that fits.
Measured. Opens, clicks, and unsubscribes tracked so the next issue is better.
SPF, DKIM, DMARC and warm-up so your mail lands in the inbox, not the spam folder.
Tag on signup, behaviour, or purchase; send the right message to the right people.
Your list, your infrastructure, exportable any time. No per-subscriber pricing.
