Notify vs Postmark
Postmark is a respected transactional specialist with an official SDK and message streams. Notify is the minimal alternative: one send call, flat pricing, logs and webhooks.
| Feature | Notify | Postmark |
|---|---|---|
| Focus | Minimal transactional API: send, webhooks, logs | Transactional email with strong deliverability reputation |
| Recommended client | One `fetch` — no official SDK required | `postmark` Node SDK (`ServerClient.sendEmail`) is the usual path |
| Auth | `x-api-key` header | `X-Postmark-Server-Token` (per server) |
| Send body | `to`, `subject`, `message` | `HtmlBody` / `TextBody` (+ templates / MessageStream) |
| Entry paid pricing | Pro: $10/mo for 10,000 emails | Basic starts at $15/mo for 10,000 — confirm current Postmark pricing |
| Free tier | 1,000 emails/mo | Developer plan: 100 emails/mo (permanent free tier) |
| Product surface | Deliberately small dashboard | Message streams, templates, richer ops UI |
Choose Notify if…
You want the smallest honest API, flat Pro pricing at $10 / 10k, and you already own your HTML (or generate it).
Choose Postmark if…
You specifically want Postmark’s brand, message streams, and are happy to pay for that positioning at your volume.
Best for
Indie hackers and startups shipping transactional mail who optimize for simplicity and predictable cost.
Not for
Teams standardized on Postmark’s template/streams workflow who do not want to change providers.
Reputation vs surface area
Postmark earned trust by staying transactional. Notify takes a similar stance, but bets harder on minimal: you pass message, we deliver, you watch logs and webhooks — no official SDK required.
Cutover: Migrate from Postmark.
Frequently asked questions
Is Postmark “better” at deliverability?
Postmark has a long-standing reputation for transactional deliverability and stays transactional-only. Notify optimizes for a minimal API and fair flat pricing. Domain setup (SPF/DKIM), content quality, and list hygiene matter on every provider.
Can I migrate from Postmark?
Yes. Replace ServerClient.sendEmail with a Notify fetch, map HtmlBody/TextBody to message, swap the server token for x-api-key, verify your domain, and recreate webhooks.
Who should pick Notify?
Builders who want password resets, receipts, and notifications without ESP sprawl — and who want Pro pricing that is easy to explain ($10 / 10k).
