Notify vs Mandrill
Mailchimp Transactional (Mandrill) still documents POST to mandrillapp.com with the key in the JSON body — usually via the official Node client. Notify is standalone and minimal: one fetch, flat pricing, logs and webhooks.
| Feature | Notify | Mandrill |
|---|---|---|
| Focus | Minimal transactional API: send, webhooks, logs | Mailchimp Transactional (formerly Mandrill) |
| Recommended client | One `fetch` — no official SDK required | `@mailchimp/mailchimp_transactional` (`messages.send`) |
| Auth | `x-api-key` header | API key in JSON body (`key`) — all calls are POST |
| Endpoint | `POST https://notify.cx/api/email/send` | `POST https://mandrillapp.com/api/1.0/messages/send.json` |
| Send body | `to`, `subject`, `message` | Nested `message.html` / `message.text` (+ templates) |
| Entry paid pricing | Pro: $10/mo for 10,000 emails | Mailchimp Transactional add-on pricing — confirm current tiers |
| Product surface | Deliberately small dashboard | Tied to Mailchimp account; templates / SMS also in the ecosystem |
Choose Notify if…
You want a thin transactional API and do not need Mailchimp’s marketing suite in the same vendor.
Choose Mandrill if…
You already run Mailchimp + Mandrill and prefer one ecosystem for campaigns and transactional mail.
Best for
Indie hackers and startups shipping transactional mail who optimize for simplicity and predictable cost.
Not for

Frequently asked questions
Can I migrate from Mandrill?
Yes. Replace mailchimp.messages.send with a Notify fetch, flatten nested message.html/text into message, move the key into an x-api-key header, verify your domain, and recreate webhooks.
Who should pick Notify?
Builders who want transactional send without living inside the Mailchimp ecosystem — and who want flat Pro pricing at $10 / 10k.
When should I stay on Mandrill?
If your org already runs Mailchimp marketing and Mandrill transactional as one stack and switching would cost more than it saves.
