Resend is a genuinely good, mature email API. The difference with Sendable is simple: with Resend you write and maintain the templates — with Sendable, you describe the event and it writes the message for you.
If you're happy hand-writing React or HTML email templates, Resend is excellent and you probably don't need to switch. But if the part you dislike is maintaining templates that drift from what your product actually does, that's the specific problem Sendable was built to remove.
| Resend | Sendable | |
|---|---|---|
| How you write email | You design a template (React Email / HTML) | You describe the event; it writes the copy |
| New message type | New template file | New string: send(to, 'order_shipped', {…}) |
| Keeping copy current | Edit templates by hand | Nothing to maintain — copy follows the event |
| Data safety | You control the template | Values inserted verbatim; a second model blocks unsupported claims |
| Maturity | Established, battle-tested at scale | New — honest about that |
| Free tier | Yes | 500 messages/mo, no card |
import { send } from 'sendableme';
await send('sam@example.com', 'order_shipped', { orderId: 'A-1042', eta: 'Friday' });
No template file. Sendable writes the subject and body from the event name and your field names, inserts your data verbatim, and sends it.
Choose Resend if you want full control of pixel-perfect templates, need a long track record at high volume, or already have templates you're happy with.
Choose Sendable if you'd rather never write or maintain a template again, and you want the copy to always match what your product does. Sendable is newer — email only, no batch/scheduling/webhooks yet.
500 messages a month, no card. One function call to integrate.
