Official SDKs for TypeScript, Python, and Go with typed responses, automatic retries, and full API coverage. Or use the REST API directly — it’s just HTTP.
import { Sendr } from 'sendr';
const sendr = new Sendr(process.env.SENDR_API_KEY);
await sendr.emails.send({
from: 'noreply@yourapp.com',

“Scoped API keys and suppression lists meant we could give our client teams access without worrying about them nuking our sender reputation.”
