Lightweight transactional email
If you searched for a simple email API for developers — not another marketing cloud — Notify is built for that: send the email, watch the logs, move on. Official notifycx SDK and notifycx-mcp included.
| Feature | Notify | Typical lightweight / DIY |
|---|---|---|
| Job to be done | Send app email; observe delivery | Varies — some are SMTP relays, some mini-ESPs |
| Surface area | Send + webhooks + logs | Often grow into templates, forms, newsletters |
| Auth | x-api-key | SMTP passwords, Bearer tokens, or proprietary SDKs |
| Pricing clarity | Free 1k / Pro $10 / Scale $50 | Mixed — some cheap, some opaque credit systems |
| AI / MCP angle | `notifycx` / `fetch` in apps; official `notifycx-mcp` for IDE agents | Some push agent wrappers you may not need |
| vs raw SES | Thin DX layer on delivery infra | SES is cheaper at scale; you build logs/webhooks |
| Best for | Indie hackers & startups shipping transactional mail | Depends — match the tool to transactional vs marketing |

Frequently asked questions
What counts as lightweight?
An API you can integrate in an afternoon: credentials, verify domain, POST HTML. No newsletter suite required to get value.
When should I use SES instead?
When volume is high and your team will own logging, suppression, webhooks, and DX. Notify is that thin layer when you would rather not.
Do I need an official SDK or MCP?
Optional. Use notifycx or fetch in app code; connect notifycx-mcp in IDE coding agents. Same send API either way.
