Notes from building.
Less polished than the resource articles. Founder takes, infrastructure war stories, and product-launch posts.
Shipping the BoomSauce API
The full v1 API is now public, paired with a Node SDK on npm. Four lines of TypeScript to send your first email. Per-key scopes, IP allowlist, automatic retries with exponential backoff, idempotency stamping on every write, HMAC webhook verification in one function. A walk-through of what we built, what we deliberately didn't, and the architecture decisions behind both.
Why we built BoomSauce
Cold outreach is broken because the tool stack is fragmented. Sequencing tools don't handle deliverability. Deliverability tools don't do sequencing. Domain registration sits at a third vendor. Warmup at a fourth. We bundled it because every team we talked to was trying to glue together the same five products.
