Agentic Brief
An owned AI publishing system that turns a reader’s stated interests into a confirmed, structured preference profile before any edition is sent.
The challenge
Collect useful reader intent without creating a spam-prone form, an unverified mailing list, or a generic one-size-fits-all newsletter.
The product needs more than an email address to be useful, but every additional input adds friction and a new abuse surface. The onboarding therefore had to capture meaningful interests in one pass, verify that the reader owns the address, and only then turn the submission into routable publishing data.
Engineering depth
Preference and intent model
The form captures topics and reader intent as structured fields, creating a usable profile for segmentation instead of burying useful context inside an unsearchable free-text note.
Validation and abuse controls
Input limits, email normalization, domain mail checks, a honeypot, a strict request-body ceiling, and rate limiting reject obvious abuse before it reaches the delivery workflow.
Signed double opt-in
A compact, expiring confirmation token binds the subscription data to a 24-hour verification link. Tampered or expired tokens fail without activating the reader.
Confirmed routing
Only a verified submission is scored and routed. Idempotent email operations and privacy-safe security logs make retries observable without leaking raw addresses into the audit trail.
My role
-
01
Designed the onboarding around what the reader wants to follow, not around a generic email capture.
-
02
Built the server-side validation, mail-domain checks, honeypot, body limit, and request-rate controls.
-
03
Implemented the signed 24-hour confirmation flow, including tamper, expiry, and replay-safe behavior.
-
04
Connected verified preferences to qualification and delivery while keeping the public product readable to search and AI answer systems.
The achievement
A production double-opt-in and preference pipeline—not a form that drops unverified addresses into a list.
The finished flow turns a small signup form into a permission and data pipeline. It verifies address ownership, preserves the reader’s interests as structured data, blocks delivery before confirmation, and leaves a clean operational trail for failures and retries. That gives Agentic Brief a sound base for genuinely preference-led publishing.
- No unverified submission enters the active delivery path; the reader must complete the signed confirmation first.
- Each confirmed reader arrives with structured interests and intent instead of an isolated address.
- Rate limits, mail-domain validation, idempotent delivery, and privacy-safe logs make the flow operable as a real product.
