- Create an account.
- Verify your sending domain. This is required: Elastic Email only sends from verified domains.
- Create an API key under Settings → Manage API Keys.
- Send your first email, using an address on your verified domain as the sender:
curl -X POST https://api.elasticemail.com/v4/emails/transactional \
-H "X-ElasticEmail-ApiKey: $ELASTICEMAIL_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"Recipients": { "To": ["recipient@example.com"] },
"Content": {
"From": "you@your-domain.com",
"Subject": "Hello from Elastic Email",
"Body": [{ "ContentType": "HTML", "Content": "<p>It works!</p>" }]
}
}'Then choose an SDK for your language below. Each repository has a quick start and examples.
Every SDK wraps the same REST API v4, so the same endpoints and models are available in every language.
