Send Email with Resend
Overview
Resend provides two endpoints for sending emails:
| Approach | Endpoint | Use Case |
|---|---|---|
| Single | POST /emails |
Individual transactional emails, emails with attachments, scheduled sends |
| Batch | POST /emails/batch |
Multiple distinct emails in one request (max 100), bulk notifications |
Choose batch when:
- Sending 2+ distinct emails at once
- Reducing API calls is important (by default, rate limit is 2 requests per second)
- No attachments or scheduling needed
Choose single when:
- Sending one email
- Email needs attachments
