The marketing wing.

Campaigns, automations and topics — in the same house as the email your product already sends, on the domain reputation you already earned. No second tool, no second list.

Draft freely in the sandbox · Sending ships with paid plans

#01 — Campaigns

Compose once. Pick who. Send.

Compose with a saved template or raw HTML, pick a segment, send now or schedule for later. Every campaign reports its own delivery and engagement metrics, and every send rides the domain reputation your transactional mail already warmed — nothing goes to anyone who hasn't opted in to that topic.

#02 — Automations

Welcome to winback, while you ship.

The sequence

Plain steps, no canvas maze.

An automation is a multi-step sequence you can read aloud: triggered by a signup, an event, or an inbound reply, with delays and branches between sends, and stop conditions that end it the moment someone converts or unsubscribes. Set it once and it runs while you ship.

#03 — Topics & preferences

The reader chooses what arrives.

Every campaign belongs to a topic — news, tips, billing, yours to define. Readers manage their own subscriptions on a hosted preference page, and every send carries one-click unsubscribe scoped to that topic, not a nuclear opt-out.

DRIN POSTAGE · SERIES 03 — CONSENTSHEET OF 3

Per-topic subscriptions — a reader can leave the newsletter and keep billing notices.

  • Per-topic subscription state on every contact
  • Topics are yours to define — news, tips, billing
  • Transactional mail is never caught in an opt-out

A hosted page where readers manage their own subscriptions — no support ticket required.

  • Hosted by Drin, linked from every campaign
  • Readers flip topics on and off themselves
  • Changes apply to the very next send
03.3One-click unsubscribe

Every campaign carries the one-click header, scoped to its topic. Compliance is the default, not a setting.

  • One-click unsubscribe headers on every send
  • Scoped to the topic, not a nuclear opt-out
  • Compliance by default — nothing to configure
#04 — Approve-by-reply

Nothing blasts without a human reply.

Whether a teammate or an agent drafted it, a campaign launches one way: the approval email lands in your inbox, and you reply APPROVE. The audit trail is your own mail archive.

#05 — Bring your list

Import contacts by CSV or API. Consent comes along — topics and suppressions apply from the first send.

Segments are built from what contacts do — joined recently, opened lately, replied ever — not from lists you have to weed by hand. And your transactional suppressions already protect every campaign.
