## Product

**Cadence** is an email-sending API for developers and product teams. It lets engineers send
transactional and marketing email from their applications with a few lines of code, and gives
non-engineers a way to write, manage, and schedule those emails without touching the codebase.

## Who it's for

Developers integrating email into a product, plus the marketing and product people on the same team
who own the content of those emails.

## What it does

- A simple REST API and SDKs to send email from application code.
- Deliverability tooling: domain authentication, suppression handling, and bounce/complaint tracking.
- A way to author emails as reusable templates, including from React-style components.
- Analytics on opens, clicks, deliveries, and bounces.
- A test/preview mode so teams can see an email before it ships.

## What the landing page must communicate

- That sending email from code is genuinely simple here (show, don't claim).
- That deliverability is handled — the hard, invisible part of email is taken care of.
- That both engineers and content owners have a place in the workflow.
- Credibility: this is production infrastructure, not a toy.

## Primary call to action

Get started / sign up with an API key.

## Constraints

- Honest, concrete copy about what the product does — no vague promises.
- The page should read as current, well-resourced SaaS for a technical audience.
