The problem
Outreach has to be paced, compliant and deliverable: honour one-click unsubscribes, stay inside mailbox limits, and recover cleanly when a send fails — without a web request doing the sending.
The solution
Campaigns are queued, not sent, by the request that starts them. A scheduled worker claims batches with FOR UPDATE SKIP LOCKED, checks suppression and send windows, reserves a mailbox slot (caps, warm-up, pacing) in one atomic update, then sends and records the outcome.
My role
I built it: the commit history of its repository is mine — product decisions, architecture and code.

Technical challenges
The engineering problems this build had to get right.
- Pacing lives in the database so worker time is spent sending, not sleeping
- Failures classified into reconnect, bounce, or retry with backoff and jitter
- HMAC-signed, purpose-separated tokens for unsubscribe and tracking links

Implementation — what shipped
Engineering notes
Lesson for similar SaaS builds: design for pacing lives in the database so worker time is spent sending, not sleeping and failures classified into reconnect, bounce, or retry with backoff and jitter up front — these are the parts that are expensive to retrofit once the feature list grows.
