Email marketing that actually sends

Capture subscribers on your page (or with an embeddable form on any website), segment them, and send broadcasts and automations as real email from OpenBio’s verified domain. Every message is logged per recipient: queued, then sent.

Capture everywhere

Email and phone forms as page blocks, lead forms with your own fields, locked content that unlocks by email, and an embed form snippet for external sites. Each subscriber is stored with their source, browser language and country. Forms carry a hidden honeypot so bots subscribe to nothing. Import and export your list as CSV any time — it is your audience, not ours.

Segments & broadcasts

Build segments by source, language or country and send a broadcast to exactly that slice. Personalise with {name} and {email}. The delivery log shows every recipient and status — no silent failures, no fake “sent” counters.

Automations

A welcome email the moment someone subscribes, and a follow-up after every free claim — created for you on every new page, editable in the Studio (trigger, subject, body), and firing for real. SMS subscribers are collected the same way; automated SMS sending is not wired yet, and the Studio says so plainly.
